Description

Technical Field

[0001] This application relates to the field of motor technology, and more specifically, to an insulating end plate for a stator, a stator, a motor, a compressor, and a vehicle. Background Technology

[0002] During stator assembly, insulating end plates are used to separate the windings from the stator core to avoid direct contact between the windings and the stator core.

[0003] In related technologies, if the insulation end plate is not set properly, the winding and the insulation end plate cannot fit tightly together, which can easily lead to the winding coming loose. It will also increase the material input of the winding and increase the production cost of the motor. Utility Model Content

[0004] This application aims to address at least one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the first aspect of this application proposes an insulating end plate for a stator.

[0006] The second aspect of this application proposes a stator.

[0007] The third aspect of this application proposes an electric motor.

[0008] The fourth aspect of this application proposes a compressor.

[0009] The fifth aspect of this application proposes a vehicle.

[0010] In view of the above, a first aspect of this application provides an insulating end plate for a stator, comprising: a blocking portion; a winding portion; and a passing portion. Along the radial direction of the stator, the passing portions are spaced apart on one side of the blocking portion. Each passing portion includes: a connecting section, with the winding portion connected between the connecting section and the blocking portion; an inlet section; and an outlet section. Both the inlet and outlet sections are connected to a first axial end face of the connecting section. Along the circumference of the stator, the inlet and outlet sections are spaced apart to enclose a passing groove. Along the radial direction of the stator, both the inlet and outlet sections have a first radial end face and a second radial end face, with the first radial end face closer to the blocking portion than the second radial end face. One of the inlet and outlet sections has a first conductor groove on its first radial end face, and the other has a second conductor groove on its second radial end face. The first conductor groove and the second conductor groove are connected through the passing groove.

[0011] The insulating end plate of a stator provided in this application includes a blocking part, a winding part, and a wire-passing part. The wire-passing part includes a connecting section, a leading section, and a leading section.

[0012] Along the radial direction of the stator, the blocking section and the guide section are arranged opposite to each other and spaced apart. The winding section is connected between the connecting section and the blocking section. That is, the winding section is connected between the blocking section and the guide section. The blocking section, the winding section, and the guide section enclose a winding groove, and a portion of the stator winding is wound in the winding groove.

[0013] The connecting section has a first axial end face. The inlet section is connected to the first axial end face of the connecting section, and the outlet section is also connected to the first axial end face. That is, along the axial direction of the stator, the inlet section and the outlet section are connected to the same side of the connecting section, and the inlet section and the outlet section are arranged at intervals in the circumferential direction of the stator. The inlet section, the outlet section, and the connecting section enclose a wire guide groove.

[0014] Along the radial direction of the stator, the guide section has a first radial end face and a second radial end face arranged opposite to each other and spaced apart, with the first radial end face closer to the blocking portion than the second radial end face. Along the radial direction of the stator, the guide section has a first radial end face and a second radial end face arranged opposite to each other and spaced apart, with the first radial end face closer to the blocking portion than the second radial end face. One of the guide and guide sections has a first wire groove on its first radial end face, and the other has a second wire groove on its second radial end face. That is, the first radial end face of the guide section has a first wire groove, and the second radial end face of the guide section has a second wire groove. Alternatively, the second radial end face of the guide section has a first wire groove, and the first radial end face of the guide section has a second wire groove. In other words, one of the guide and guide sections has a first wire groove, and the other has a second wire groove. In other words, along the radial direction of the stator, the guide section has a first wire groove and a second wire groove on different sides, and the concave directions of the first and second wire grooves are different.

[0015] The first and second conductor slots are connected by a through-slot. Thus, the winding wire first winds into the first or second conductor slot in the inlet section, and then winds into the second or first conductor slot in the outlet section via the through-slot. It is understood that the first and second conductor slots are located on different sides of the through-slot along the stator's radial direction. This ensures that the winding wire fits tightly against the first and second conductor slots during winding, and also fits tightly against the stator's insulating end plate. This effectively prevents the winding wire from falling off the stator's insulating end plate due to loosening, and also prevents the winding wire from protruding radially and being damaged. This reduces the material usage of the winding section, lowers the motor's production cost, reduces copper losses, and improves the motor's efficiency.

[0016] In addition, this setting allows the end wire to be routed through the lead-in and lead-out sections of the winding section after one tooth of the stator is wound. This enables different coils in the winding section to be connected without breaks through the same winding (e.g., enameled wire). This is beneficial for improving the insulation performance of the motor, reducing wire ends, facilitating automated winding of the equipment, improving production efficiency, and reducing production costs.

[0017] The insulating end plate of the stator described above in this application may also have the following additional technical features:

[0018] In some embodiments, optionally, there are multiple first wire slots and multiple second wire slots, with the multiple first wire slots arranged at intervals along the axial direction of the stator, and each first wire slot cooperating with a second wire slot.

[0019] In this embodiment, the number of the first wire groove and the second wire groove and their mating structure are further defined.

[0020] Specifically, there are multiple first wire slots and multiple second wire slots. Multiple first wire slots are arranged at intervals along the axial direction of the stator. Multiple second wire slots are also arranged at intervals along the axial direction of the stator.

[0021] In this configuration, each first wire slot is paired with one second wire slot. That is, the number of first and second wire slots is matched, and each first wire slot corresponds to one second wire slot. It can be understood that the first wire slot and its corresponding second wire slot are connected via a through-slot. Thus, according to specific practical needs, multiple first and second wire slots can be divided into multiple wire slot groups, each consisting of one first wire slot and one corresponding second wire slot. This allows for winding different phases of wire in different wire slot groups, as well as winding the same phase in different wire slot groups. This design ensures the insulation performance of the motor while meeting diverse usage requirements, thus improving product performance and market competitiveness.

[0022] It is understandable that the first and second conductor slots are arranged alternately, and the winding is confined within the first and second conductor slots. Electrical isolation between different phases of the motor can be achieved without additional insulation protection, and the insulation performance is high.

[0023] In some embodiments, optionally, the first guide slot and the cooperating second guide slot are located at the same height along the axial direction of the stator.

[0024] In this embodiment, the mating structure of the first wire groove and the second wire groove is further defined.

[0025] Specifically, along the stator's axial direction, the first conductor slot and its mating second conductor slot are located at the same height. For example, along the stator's axial direction, the distance from the first conductor slot to the connecting section is equal to the distance from the second conductor slot to the connecting section. In other words, along the stator's axial direction, the first and second conductor slots are at the same height. This arrangement helps reduce the winding difficulty of the winding section, reduces the probability of winding breakage, facilitates seamless connection of different coils using the same winding, and improves product assembly efficiency. Furthermore, compared to the arrangement along the stator's axial direction, this structure has a height difference between the first and mating second conductor slots, reducing the material usage in the winding section, thus lowering motor production costs, reducing copper losses, and improving motor efficiency.

[0026] In some embodiments, optionally, the wall of at least one of the first wire groove and the second wire groove is an arc-shaped wall.

[0027] In this embodiment, the structures of the first wire groove and the second wire groove are further defined.

[0028] Specifically, at least one of the first and second wire grooves has an arc-shaped wall. That is, the wall of the first wire groove is an arc-shaped wall. Alternatively, the wall of the second wire groove is an arc-shaped wall. Or, the wall of both the first and second wire grooves is an arc-shaped wall.

[0029] This design allows the winding to fit tightly against the curved wall while preventing rubbing against the winding and avoiding damage during winding, thus providing reliable structural support to ensure the performance of the motor.

[0030] Specifically, the curved wall extends circumferentially in the stator.

[0031] After the segmented motor is unwound and wound, the segmented motor is assembled into a circle. The winding (i.e., enameled wire) at the insulating end plate of the stator can be tightly fitted into the first and second wire slots, preventing the enameled wire from loosening and thus increasing the outer diameter of the stator, and avoiding damage to the enameled wire.

[0032] It is understandable that the shape of the curved wall matches the outer wall of the winding. When the winding is assembled with the curved wall, the stress at the connection between the curved wall and the winding is small and will not damage the winding.

[0033] In some embodiments, optionally, when the lead-out section is provided with a first wire groove, the lead-out section includes: a lead-out body connected to the connecting section; a plurality of first protrusions connected to the side of the lead-out body away from the lead-in section, the plurality of first protrusions being spaced apart in the axial direction of the stator, and any two adjacent first protrusions enclosing the first wire groove.

[0034] In this embodiment, the structure of the leading segment is defined based on the fact that the leading segment is provided with a first wire groove.

[0035] The export segment includes an export body and multiple first protrusions. The export body is connected to the connecting segment; specifically, the export body is connected to the first axial end face of the connecting segment.

[0036] Multiple first protrusions are connected to the export body, which serves as the mounting carrier for the multiple first protrusions, and has the function of installing and fixing the multiple first protrusions. This ensures the mating structure of the multiple first protrusions.

[0037] Specifically, any one of the plurality of first protrusions is connected to the export body, and the first protrusion is connected to the side of the export body opposite to the import segment. That is, any one of the plurality of first protrusions protrudes out of the circumferential end face of the export body.

[0038] Multiple first protrusions are arranged at intervals along the axial direction of the stator, and any two adjacent first protrusions enclose a first wire groove. This arrangement ensures the effectiveness and feasibility of forming the first wire groove while reducing the amount of material used in the wire guide section, thus reducing the production cost of the motor.

[0039] Understandably, the first protrusion extends beyond the first radial end face of the guide section. This arrangement allows two adjacent first protrusions to engage, effectively limiting the winding of the winding section along the axial direction of the stator, thus preventing the winding from slipping out of the first conductor slot.

[0040] In some embodiments, optionally, when the guide section is provided with a second wire groove, the guide section includes: a guide body connected to the connecting section; a plurality of second protrusions, each of the plurality of second protrusions being connected to the side of the guide body away from the blocking portion, the plurality of second protrusions being spaced apart in the axial direction of the stator, and any two adjacent second protrusions and the guide body enclosing the second wire groove.

[0041] In this embodiment, the structure of the inlet segment is defined based on the fact that the inlet segment is provided with a second wire groove.

[0042] The import segment includes an import body and multiple second protrusions. The import body is connected to the connecting segment; specifically, the import body is connected to the first axial end face of the connecting segment.

[0043] Multiple second protrusions are connected to the guide body, which serves as the mounting carrier for the multiple second protrusions, and has the function of installing and fixing the multiple second protrusions. This ensures the mating structure of the multiple second protrusions.

[0044] Specifically, any one of the plurality of second protrusions is connected to the inlet body, and the second protrusion is connected to the side of the inlet body opposite to the blocking part. That is to say, any one of the plurality of second protrusions protrudes out of the inlet body.

[0045] Any two adjacent second protrusions and the guide body enclose a second conductor groove. This arrangement increases the contact area and contact angle between the second conductor groove and the winding of the winding section, effectively limiting the winding of the winding section along the axial and radial directions of the stator. This prevents the winding from loosening out of the second conductor groove and provides reliable structural support for a tight fit between the winding section and the insulating end plate of the stator.

[0046] In some embodiments, optionally, when the lead-out section is provided with a first wire groove, a third protrusion is provided on the side of the lead-out section away from the blocking part, and the third protrusion is used for the installation and positioning of the lead-out section.

[0047] In this embodiment, the structure of the derived segment is further defined.

[0048] Specifically, when the lead-out section has a first conductor groove, a third protrusion is provided on the side of the lead-out section away from the blocking part. During stator assembly, the stator end cover has a groove, and the third protrusion is inserted into the groove. That is, the third protrusion is used for the installation and positioning of the lead-out section to limit the mating dimensions of the stator's insulating end plate and the end cover, so that the stator's insulating end plate cannot be displaced relative to the end cover. This provides structural support to ensure the mating dimensions of the various components of the stator.

[0049] In some embodiments, optionally, a fourth protrusion is provided on the side of the connecting segment away from the winding portion, and the fourth protrusion is located at the second axial end face of the connecting segment.

[0050] In this embodiment, the structure of the line-crossing portion is further defined.

[0051] Specifically, the connecting section has a fourth protrusion on the side opposite to the winding section. That is, the connecting section has a fourth protrusion, the connecting section is located between the fourth protrusion and the winding section, the fourth protrusion extends radially along the stator, and the fourth protrusion is located at the second axial end face of the connecting section.

[0052] When the stator core is assembled with the stator insulation end plate, the fourth protrusion abuts against the axial end face of the stator core. This arrangement increases the assembly area between the stator core and the stator insulation end plate. Therefore, during winding, it reduces the probability of the stator insulation end plate tilting relative to the stator core, and also reduces the probability of displacement of the stator insulation end plate relative to the stator core. This ensures the fit dimensions of the stator core, the stator insulation end plate, and the winding section, providing structural support for ensuring the fit dimensions of all components of the stator.

[0053] Furthermore, since the connecting section has a fourth protrusion on the side away from the winding section, the fourth protrusion will not obstruct the winding of the winding section, thus avoiding interference with the winding of the winding section and not affecting the winding dimensions of the winding section.

[0054] In addition, since the fourth protrusion is located at the second axial end face of the connecting section, the mating dimensions between the fourth protrusion and the stator core can be guaranteed, so that the fourth protrusion can effectively abut against the axial end face of the stator core, thus ensuring the mating dimensions between the fourth protrusion and the stator core and effectively preventing the stator insulation end plate from shifting relative to the stator core.

[0055] In some embodiments, the number of fourth protrusions may be multiple, and the multiple fourth protrusions are arranged at circumferential intervals along the stator.

[0056] In this embodiment, the number of fourth protrusions and the location of the fourth protrusions are further defined.

[0057] Specifically, there are multiple fourth protrusions, which are arranged at intervals along the circumference of the stator.

[0058] This design increases the area of ​​the stator's insulating end plate that mates with the stator core. When winding the winding section, it reduces the probability of the stator's insulating end plate tilting relative to the stator core and the probability of the stator's insulating end plate shifting relative to the stator core. It ensures the mating dimensions of the stator core, the stator's insulating end plate, and the winding section, providing structural support for ensuring the mating dimensions of all components of the stator.

[0059] In some embodiments, the second axial end face of the connecting segment may optionally have a fifth protrusion, which is used for mounting and positioning the connecting segment.

[0060] In this embodiment, the structure of the line-crossing portion is further defined.

[0061] Specifically, the second axial end face of the connecting section is provided with a fifth protrusion. That is, the connecting section is provided with a fifth protrusion, which is located at the second axial end face of the connecting section and extends along the axial direction of the stator.

[0062] The third axial end face of the stator core is provided with a positioning hole. When the stator core is assembled with the stator insulation end plate, the fifth protrusion extends into the positioning hole of the stator core. This feature increases the mating area between the stator core and the stator insulation end plate, ensuring the mating dimensions between them. Thus, during winding, the probability of the stator insulation end plate tilting relative to the stator core is reduced, as is the probability of displacement of the stator insulation end plate relative to the stator core. This ensures the mating dimensions of the stator core, the stator insulation end plate, and the winding section, providing structural support for ensuring the mating dimensions of all components of the stator.

[0063] In some embodiments, the insulating end plate of the stator may optionally include two limiting plates along the axial direction of the stator, with the blocking portion, the winding portion and the passing portion connected to the same side of the limiting plates, and the two limiting plates being arranged at intervals in the circumferential direction of the stator to enclose the core slot.

[0064] In this embodiment, the structure of the insulating end plate of the stator is further defined.

[0065] Specifically, the insulating end plate of the stator also includes two limiting plates, which are arranged at intervals along the circumference of the stator.

[0066] Any one of the blocking part, the winding part, and the passing part is connected to the limiting plate, and along the axial direction of the stator, the blocking part, the winding part, and the passing part are located on the same side of the limiting plate.

[0067] Specifically, the two limiting plates, the blocking part, the winding part and the passing part enclose the iron core slot.

[0068] When the stator core is assembled with the stator insulation end plate, a portion of the stator core extends into the core slot. This arrangement increases the mating area between the stator core and the insulation end plate, ensuring the appropriate mating dimensions. This reduces the probability of the insulation end plate tilting relative to the stator core during winding, and also reduces the probability of displacement of the insulation end plate relative to the stator core. It ensures the appropriate mating dimensions of the stator core, insulation end plate, and winding section, providing structural support for maintaining the appropriate mating dimensions of all stator components.

[0069] In some embodiments, the winding portion may optionally be provided with a clearance groove located between two limiting plates.

[0070] In this embodiment, the structure of the insulating end plate of the stator is further defined.

[0071] Specifically, the axial end face of the winding section is provided with a clearance groove. The clearance groove and the limiting plate are located on the same side of the winding section. The clearance groove is located between the two limiting plates. The clearance groove is used to avoid certain structural elements of the stator core, such as the rivet portion of the stator core. This design ensures the proper fit between the stator core and the stator's insulating end plate, preventing the insulating end plate from being lifted and tilted by the stator core. It provides structural support for ensuring the effective fit between the stator core and the insulating end plate.

[0072] In addition, this structural design can enhance the structural strength and rigidity of the stator's insulating end plate, reduce the probability of deformation when the stator's insulating end plate is wound with the winding section, and provide structural support to ensure the stator's external dimensions.

[0073] Optionally, the fourth protrusion is located on one side of the clearance groove along the radial direction of the stator. For example, the fourth protrusion is located on the outside of the clearance groove along the radial direction of the stator.

[0074] In some embodiments, the first circumferential end face of the connecting segment is provided with a notch, and the second circumferential end face of the connecting segment is provided with a sixth protrusion.

[0075] In this embodiment, the structure of the connecting segment is further defined.

[0076] Specifically, along the circumferential direction of the stator, the connecting section has a first circumferential end face and a second circumferential end face arranged opposite to each other and spaced apart. The first circumferential end face of the connecting section is provided with a notch, and the second circumferential end face of the connecting section is provided with a sixth protrusion.

[0077] The stator comprises multiple stator insulating end plates. When assembling multiple stator insulating end plates, in two adjacent stator insulating end plates, the sixth protrusion of one stator insulating end plate is inserted into the notch of the other stator insulating end plate. That is, the notch of one stator insulating end plate is used to allow the sixth protrusion of another stator insulating end plate to be inserted. This ensures the proper fit dimensions of the multiple stator insulating end plates.

[0078] The second aspect of this utility model provides a stator, comprising: a stator core; a plurality of insulating end plates of the stator in the first aspect, the plurality of insulating end plates of the stator being located on the same side of the stator core along the axial direction of the stator, wherein in two adjacent insulating end plates of the stator, a sixth protrusion of the insulating end plate of one stator is inserted into a notch of the insulating end plate of the other stator; and a winding portion, the winding portion being wound around the stator core through the insulating end plates.

[0079] The stator provided by this utility model includes a stator core, multiple stator insulating end plates, and a winding section. Since the stator includes the insulating end plates as described in the first aspect, it possesses all the beneficial effects of the aforementioned stator insulating end plates, which will not be elaborated upon here.

[0080] In some embodiments, the winding portion may optionally have a winding, a portion of which is disposed in a first conductor groove and a second conductor groove; when the lead section is provided with a second conductor groove, the minimum distance between the end faces of two adjacent second protrusions of the stator's insulating end plate that are close to each other is greater than 1.5 times the outer diameter of the winding.

[0081] The winding section has a winding wire, a portion of which is located in the first and second conductor slots. That is, the winding wire of the winding section is wound around the second conductor slot in the inlet section and then around the first conductor slot in the outlet section. It can be understood that, along the radial direction of the stator, the first and second conductor slots are located on different sides of the winding section. This allows the winding wire to fit tightly against the first and second conductor slots during winding, meaning the winding wire can fit tightly against the stator's insulating end plate. This effectively prevents the winding wire from loosening and falling off the stator's insulating end plate, and also effectively prevents the winding wire from protruding radially and being damaged. This helps reduce the material usage of the winding section, lowers the motor's production cost, reduces copper losses, and improves the motor's efficiency.

[0082] Furthermore, the minimum distance between the end faces of two adjacent second protrusions on the stator's insulating end plate is greater than 1.5 times the outer diameter of the winding. This defines the matching structure between the distance between two adjacent second protrusions and the outer diameter of the winding. This ensures that the winding can be completely placed within the second conductor slot when the end passes through, preventing the winding from slipping and improving the insulation reliability of the motor.

[0083] In some embodiments, the minimum distance between the end faces of the inlet and outlet segments that are close to each other is greater than four times the outer diameter of the winding.

[0084] In this embodiment, the mating structure of the winding section and the insulating end plate of the stator is further defined.

[0085] Specifically, the minimum distance between the end faces of the lead-in section and the lead-out section is greater than four times the outer diameter of the winding. Along the circumference of the stator, the end face of the lead-in section facing the lead-out section is the first end face, and the end face of the lead-out section facing the lead-in section is the second end face. The minimum distance between the first and second end faces is greater than four times the outer diameter of the winding. This arrangement ensures a smooth transition of the winding from the lead-in section to the lead-out section during winding, preventing excessive bending of the winding (e.g., copper wire) that could damage the varnish film, thus improving the service life of the winding and the insulation performance of the motor.

[0086] In some embodiments, optionally, the third axial end face of the stator core is provided with a positioning hole, and the fifth protrusion of the insulating end plate of the stator is inserted into the positioning hole; a portion of the teeth of the stator core is inserted into the core slot of the insulating end plate of the stator.

[0087] In this embodiment, the mating structure of the stator core and the stator insulating end plate is further defined.

[0088] Specifically, the third axial end face of the stator core is provided with a positioning hole, and the insulating end plate of the stator has a fifth protrusion.

[0089] When the stator core is assembled with the stator insulation end plate, the fifth protrusion extends into the positioning hole of the stator core. This feature increases the mating area between the stator core and the insulation end plate, ensuring the mating dimensions of the stator core and insulation end plate. Thus, during winding, the probability of the insulation end plate tilting relative to the stator core is reduced, as is the probability of displacement of the insulation end plate relative to the stator core. This ensures the mating dimensions of the stator core, insulation end plate, and winding section, providing structural support for guaranteeing the mating dimensions of all components of the stator.

[0090] Specifically, when the stator core is assembled with the stator insulation end plate, a portion of the stator core extends into the core slot of the insulation end plate. This arrangement increases the mating area between the stator core and the insulation end plate, ensuring the mating dimensions between them. This reduces the probability of the insulation end plate tilting relative to the stator core during winding, and also reduces the probability of displacement of the insulation end plate relative to the stator core. It ensures the mating dimensions of the stator core, insulation end plate, and winding section, providing structural support for guaranteeing the mating dimensions of all stator components.

[0092] The motor provided by this utility model includes a stator as described in the second aspect, and therefore has all the beneficial effects of the stator mentioned above, which will not be described in detail here.

[0094] The compressor provided by this utility model includes a motor as described in the third aspect, and therefore has all the beneficial effects of the aforementioned motor, which will not be described in detail here.

[0096] The vehicle provided by this utility model includes a motor as described in the third aspect or a compressor as described in the fourth aspect, and therefore has all the beneficial effects of the aforementioned motor or compressor, which will not be described in detail here.

[0097] It is worth noting that the vehicle can be a new energy vehicle. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, and hydrogen engine vehicles.

[0098] The vehicle can also be a gasoline-powered car.

[0112] The following reference Figures 1 to 7 According to some embodiments of this application, there are stator insulating end plates 10, stator 60, motors, compressors, and vehicles.

[0113] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 As shown, an insulating end plate 10 of a stator according to some embodiments of this application includes a blocking portion 100, a winding portion 200, and a wire-passing portion 300. The wire-passing portion 300 includes a connecting section 310, an inlet section 330, and an outlet section 340.

[0114] Along the radial direction of the stator 60, the wire passing portions 300 are arranged at intervals on one side of the blocking portion 100.

[0115] The line guide section 300 includes a connecting section 310, an inlet section 330, and an outlet section 340.

[0116] The winding part 200 is connected between the connecting section 310 and the blocking part 100.

[0117] Both the inlet segment 330 and the outlet segment 340 are connected to the first axial end face 312 of the connecting segment 310.

[0118] Along the circumference of the stator 60, the lead-in section 330 and the lead-out section 340 are arranged at intervals to enclose the wire groove 350.

[0119] Along the radial direction of the stator 60, both the lead-in section 330 and the lead-out section 340 have a first radial end face 360 ​​and a second radial end face 370.

[0120] The first radial end face 360 ​​is closer to the blocking portion 100 than the second radial end face 370.

[0121] The first radial end face 360 ​​of one of the inlet segment 330 and the outlet segment 340 is provided with a first wire groove 380, and the second radial end face 370 of the other is provided with a second wire groove 390.

[0122] The first wire groove 380 and the second wire groove 390 are connected by a through groove 350.

[0123] The insulating end plate 10 of a stator provided in this application includes a blocking part 100, a winding part 200, and a wire passing part 300. The wire passing part 300 includes a connecting section 310, an inlet section 330, and an outlet section 340.

[0124] Along the radial direction of the stator 60, the blocking portion 100 and the wire-passing portion 300 are arranged opposite to each other and spaced apart. The winding portion 200 is connected between the connecting section 310 and the blocking portion 100. That is, the winding portion 200 is connected between the blocking portion 100 and the wire-passing portion 300. The blocking portion 100, the winding portion 200, and the wire-passing portion 300 enclose a winding groove, and a portion of the winding wire 710 of the stator 60 is wound in the winding groove.

[0125] The connecting section 310 has a first axial end face 312. The inlet section 330 is connected to the first axial end face 312 of the connecting section 310, and the outlet section 340 is also connected to the first axial end face 312. That is, along the axial direction of the stator 60, the inlet section 330 and the outlet section 340 are connected to the same side of the connecting section 310, and the inlet section 330 and the outlet section 340 are arranged at intervals in the circumferential direction of the stator 60. The inlet section 330, the outlet section 340, and the connecting section 310 enclose a wire groove 350.

[0126] Along the radial direction of the stator 60, the inlet section 330 has a first radial end face 360 ​​and a second radial end face 370 arranged opposite to each other and spaced apart, with the first radial end face 360 ​​being closer to the blocking portion 100 than the second radial end face 370. Along the radial direction of the stator 60, the outlet section 340 has a first radial end face 360 ​​and a second radial end face 370 arranged opposite to each other and spaced apart, with the first radial end face 360 ​​being closer to the blocking portion 100 than the second radial end face 370. Specifically, the first radial end face 360 ​​of one of the inlet section 330 and the outlet section 340 is provided with a first wire groove 380, and the second radial end face 370 of the other is provided with a second wire groove 390. That is, the first radial end face 360 ​​of the inlet section 330 is provided with a first wire groove 380, and the second radial end face 370 of the outlet section 340 is provided with a second wire groove 390. Alternatively, the second radial end face 370 of the inlet section 330 may be provided with a first guide groove 380, and the first radial end face 360 ​​of the outlet section 340 may be provided with a second guide groove 390. That is, one of the inlet section 330 and the outlet section 340 may be provided with a first guide groove 380, and the other may be provided with a second guide groove 390. In other words, along the radial direction of the stator 60, the first guide groove 380 and the second guide groove 390 are provided on different sides of the wire-passing portion 300, and the recess directions of the first guide groove 380 and the second guide groove 390 are different.

[0127] The first conductor groove 380 and the second conductor groove 390 are connected by a through groove 350. In this way, the winding 710 of the winding section 700 is first wound around the first conductor groove 380 or the second conductor groove 390 in the inlet section 330, and then wound around the second conductor groove 390 or the first conductor groove 380 in the outlet section 340 through the through groove 350. It is understandable that, along the radial direction of the stator 60, the first conductor slot 380 and the second conductor slot 390 are located on different sides of the wire-passing portion 300. In this way, when winding the winding 710 of the winding portion 700, the winding 710 can be tightly fitted to the first conductor slot 380 and the second conductor slot 390. That is, the winding 710 can be tightly fitted to the insulating end plate 10 of the stator. This can effectively prevent the winding 710 from falling off the insulating end plate 10 of the stator due to loosening, and can also effectively prevent the winding 710 from protruding in the radial direction of the stator 60 and being damaged. This is beneficial to reducing the material usage of the winding portion 700, reducing the production cost of the motor, reducing the copper loss of the motor, and improving the efficiency of the motor.

[0128] In addition, this configuration allows the end wire to be routed through the lead-in section 330 and lead-out section 340 of the winding section 300 after one tooth of the stator 60 is wound. This enables different coils of the winding section 700 to be connected without breaks through the same winding wire 710 (e.g., enameled wire). This is beneficial for improving the insulation performance of the motor, reducing wire ends, facilitating automated winding of the equipment, improving production efficiency, and reducing production costs.

[0129] Optionally, the blocking part 100, the winding part 200, and the wire-passing part 300 are integrally formed. This structure eliminates the assembly process of the blocking part 100, the winding part 200, and the wire-passing part 300, thus simplifying the assembly and subsequent disassembly of the motor, improving assembly and disassembly efficiency, and consequently reducing production and maintenance costs. Furthermore, the integral forming of the blocking part 100, the winding part 200, and the wire-passing part 300 ensures the dimensional accuracy of the stator's insulating end plate 10.

[0130] In some embodiments, optionally, such as Figure 2 , Figure 3 and Figure 5 As shown, there are multiple first wire slots 380 and multiple second wire slots 390.

[0131] Multiple first guide slots 380 are arranged at intervals along the axial direction of the stator 60.

[0132] Each first wire slot 380 mates with a second wire slot 390.

[0133] In this embodiment, the number and mating structure of the first wire groove 380 and the second wire groove 390 are further defined.

[0134] Specifically, there are multiple first guide slots 380 and multiple second guide slots 390. The multiple first guide slots 380 are arranged at intervals along the axial direction of the stator 60. The multiple second guide slots 390 are also arranged at intervals along the axial direction of the stator 60.

[0135] In this configuration, each first wire slot 380 is paired with one second wire slot 390. That is, the number of first wire slots 380 and second wire slots 390 are matched, and each first wire slot 380 corresponds to one second wire slot 390. It can be understood that the first wire slot 380 and its corresponding second wire slot 390 are connected via a through-slot 350. Thus, according to specific practical needs, multiple first wire slots 380 and multiple second wire slots 390 can be divided to form multiple wire slot groups. Each wire slot group includes one first wire slot 380 and one paired second wire slot 390. This allows for the winding of different phases 710 in different wire slot groups, as well as the winding of the same phase 710 in different wire slot groups. This configuration ensures the insulation performance of the motor while meeting diverse usage requirements, which is beneficial for improving product performance and market competitiveness.

[0136] It is understandable that the first conductor slot 380 and the second conductor slot 390 are arranged at intervals, and the winding 710 is confined within the first conductor slot 380 and the second conductor slot 390. The winding 710 between different phases of the motor can achieve electrical isolation without additional insulation protection, and the insulation performance is high.

[0137] In some embodiments, optionally, the first guide groove 380 and the cooperating second guide groove 390 are located at the same height along the axial direction of the stator 60.

[0138] In this embodiment, the mating structure of the first wire groove 380 and the second wire groove 390 is further defined.

[0139] Specifically, along the axial direction of the stator 60, the first wire slot 380 and its mating second wire slot 390 are located at the same height. For example, along the axial direction of the stator 60, the distance from the first wire slot 380 to the connecting section 310 is equal to the distance from the second wire slot 390 to the connecting section 310. In other words, along the axial direction of the stator 60, the first wire slot 380 and the second wire slot 390 are at the same height. This arrangement helps reduce the winding difficulty of the winding 710 in the winding section 700, reduces the probability of winding 710 breakage, facilitates seamless connection of different coils using the same winding 710, and improves product assembly efficiency. Simultaneously, compared to the axial direction of the stator, this structural arrangement, with a height difference between the first wire slot and its mating second wire slot, reduces the material usage of the winding section 700, thus reducing motor production costs, minimizing copper losses, and improving motor efficiency.

[0140] In some embodiments, optionally, the wall of at least one of the first wire groove 380 and the second wire groove 390 is an arc-shaped wall.

[0141] In this embodiment, the structures of the first wire groove 380 and the second wire groove 390 are further defined.

[0142] Specifically, at least one of the first wire groove 380 and the second wire groove 390 has an arc-shaped wall. That is, the wall of the first wire groove 380 is an arc-shaped wall. Alternatively, the wall of the second wire groove 390 is an arc-shaped wall. Or, the walls of both the first wire groove 380 and the second wire groove 390 are arc-shaped walls.

[0143] This design allows the winding 710 to fit tightly against the curved wall, while also preventing scratches on the winding 710 and avoiding damage to the winding 710 during the winding process, thus providing reliable structural support to ensure the performance of the motor.

[0144] Specifically, the curved wall extends circumferentially in the stator 60.

[0145] After the segmented motor is unwound and wound, the segmented motor is assembled. The winding 710 (i.e., enameled wire) at the insulating end plate 10 of the stator can be tightly fitted into the first conductor groove 380 and the second conductor groove 390, which avoids the enameled wire from loosening and thus increasing the outer diameter of the stator 60, and can avoid damage to the enameled wire.

[0146] It is understandable that the shape of the arc-shaped wall matches the outer wall of the winding 710. When the winding 710 is assembled with the arc-shaped wall, the stress at the connection between the arc-shaped wall and the winding 710 is small and will not damage the winding 710.

[0147] In this embodiment, when the first radial end face 360 ​​of the outgoing segment 340 is provided with a first wire groove 380 and the second radial end face 370 of the incoming segment 330 is provided with a second wire groove 390, the groove wall of the second wire groove 390 is an arc-shaped wall.

[0148] In some embodiments, optionally, such as Figure 2 As shown, when the export segment 340 is provided with a first wire groove 380, the export segment 340 includes an export body 342 and a plurality of first protrusions 344.

[0149] Export the main body 342 and connect it to the link segment 310.

[0150] Multiple first protrusions 344 are connected to the side of the export body 342 opposite to the import section 330.

[0151] Multiple first protrusions 344 are arranged at intervals along the axial direction of the stator 60.

[0152] Any two adjacent first protrusions 344 enclose the first wire groove 380.

[0153] In this embodiment, the structure of the lead-out segment 340 is defined based on the fact that the lead-out segment 340 is provided with a first wire groove 380.

[0154] The export segment 340 includes an export body 342 and a plurality of first protrusions 344. The export body 342 is connected to the connecting segment 310, specifically, the export body 342 is connected to the first axial end face 312 of the connecting segment 310.

[0155] Multiple first protrusions 344 are connected to the export body 342, which serves as a mounting carrier for the multiple first protrusions 344, and has the function of installing and fixing the multiple first protrusions 344. This ensures the mating structure of the multiple first protrusions 344.

[0156] Specifically, any one of the plurality of first protrusions 344 is connected to the outlet body 342, and the first protrusion 344 is connected to the side of the outlet body 342 opposite to the inlet section 330. That is, any one of the plurality of first protrusions 344 protrudes from the circumferential end face of the outlet body 342. Any one of the plurality of first protrusions 344 protrudes from the radial end face of the outlet body 342.

[0157] Multiple first protrusions 344 are spaced apart along the axial direction of the stator 60, and any two adjacent first protrusions 344 enclose a first wire groove 380. This arrangement ensures the effectiveness and feasibility of forming the first wire groove 380, while also reducing the amount of material used in the wire guide section 300 and lowering the production cost of the motor.

[0158] Understandably, the first protrusion 344 protrudes from the first radial end face 360 ​​of the lead-out section 340. This arrangement allows two adjacent first protrusions 344 to engage and effectively limit the winding 710 of the winding section 700 along the axial direction of the stator 60, preventing the winding 710 from coming loose from the first conductor slot 380.

[0159] In some other embodiments, the lead-out section 340 includes: a lead-out body 342 connected to the connecting section 310; a plurality of first protrusions 344 connected to the side of the lead-out body 342 facing the blocking part 100; the plurality of first protrusions 344 are arranged at intervals in the axial direction of the stator 60; any two adjacent first protrusions 344 and the lead-out body 342 enclose a first wire groove 380.

[0160] In some embodiments, optionally, such as Figure 2 As shown, when the inlet section 330 is provided with a second wire groove 390, the inlet section 330 includes an inlet body 332 and a plurality of second protrusions 334.

[0161] Import the main body 332 and connect it to the connection segment 310.

[0162] Multiple second protrusions 334 are connected to the side of the inlet body 332 opposite to the blocking part 100.

[0163] Multiple second protrusions 334 are arranged at intervals along the axial direction of the stator 60.

[0164] Any two adjacent second protrusions 334 and the guide body 332 enclose a second wire groove 390.

[0165] In this embodiment, the structure of the inlet section 330 is defined based on the fact that the inlet section 330 is provided with a second wire groove 390.

[0166] The inlet section 330 includes an inlet body 332 and a plurality of second protrusions 334. The inlet body 332 is connected to the connecting section 310, specifically, the inlet body 332 is connected to the first axial end face 312 of the connecting section 310.

[0167] Multiple second protrusions 334 are connected to the guide body 332, which serves as a mounting carrier for the multiple second protrusions 334, and has the function of installing and fixing the multiple second protrusions 334. This ensures the mating structure of the multiple second protrusions 334.

[0168] Specifically, any one of the plurality of second protrusions 334 is connected to the inlet body 332, and the second protrusion 334 is connected to the side of the inlet body 332 opposite to the blocking part 100. That is, any one of the plurality of second protrusions 334 protrudes out of the inlet body 332.

[0169] Any two adjacent second protrusions 334 and the guide body 332 enclose a second conductor groove 390. This arrangement increases the contact area and contact angle between the second conductor groove 390 and the winding 710 of the winding section 700, effectively limiting the winding 710 of the winding section 700 along the axial and radial directions of the stator 60. This prevents the winding 710 from loosening out of the second conductor groove 390. It provides reliable structural support for the tight fit between the winding section 700 and the insulating end plate 10 of the stator.

[0170] In some embodiments, optionally, such as Figure 2 and Figure 3 As shown, when the lead-out section 340 is provided with the first wire groove 380, the lead-out section 340 is provided with a third protrusion 346 on the side away from the blocking part 100.

[0171] The third protrusion 346 is used for the installation and positioning of the outgoing segment 340.

[0172] In this embodiment, the structure of the derived segment 340 is further defined.

[0173] Specifically, when the lead-out section 340 is provided with a first conductor groove 380, a third protrusion 346 is provided on the side of the lead-out section 340 facing away from the blocking part 100. During stator 60 assembly, the end cap of the stator 60 has a groove, and the third protrusion 346 is inserted into the groove. That is, the third protrusion 346 is used for the installation and positioning of the lead-out section 340 to limit the mating dimensions of the stator's insulating end plate 10 and the end cap, preventing the stator's insulating end plate 10 from shifting relative to the end cap. This provides structural support to ensure the mating dimensions of the various components of the stator 60.

[0174] In some embodiments, optionally, such as Figure 3 and Figure 4 As shown, the connecting section 310 has a fourth protrusion 316 on the side opposite to the winding section 200.

[0175] The fourth protrusion 316 is located at the second axial end face 314 of the connecting section 310.

[0176] In this embodiment, the structure of the line-passing portion 300 is further defined.

[0177] Specifically, the connecting section 310 has a fourth protrusion 316 on the side opposite to the winding portion 200. That is, the connecting section 310 has a fourth protrusion 316, the connecting section 310 is located between the fourth protrusion 316 and the winding portion 200, the fourth protrusion 316 extends radially along the stator 60, and the fourth protrusion 316 is located at the second axial end face 314 of the connecting section 310.

[0178] When the stator core 600 of the stator 60 is assembled with the stator insulating end plate 10, the fourth protrusion 316 abuts against the axial end face of the stator core 600. This arrangement increases the assembly area between the stator core 600 and the stator insulating end plate 10. Thus, when winding the winding portion 700, the probability of the stator insulating end plate 10 tilting relative to the stator core 600 is reduced, and the probability of the stator insulating end plate 10 shifting relative to the stator core 600 is reduced. This ensures the fit dimensions of the stator core 600, the stator insulating end plate 10, and the winding portion 700, providing structural support for ensuring the fit dimensions of all components of the stator 60.

[0179] Furthermore, since the connecting section 310 has a fourth protrusion 316 on the side away from the winding section 200, the fourth protrusion 316 will not obstruct the winding of the winding section 700, thus avoiding interference with the winding of the winding section 700 and not affecting the winding dimensions of the winding section 700.

[0180] Furthermore, since the fourth protrusion 316 is located at the second axial end face 314 of the connecting section 310, the mating dimensions between the fourth protrusion 316 and the stator core 600 can be guaranteed, so that the fourth protrusion 316 can effectively abut against the axial end face of the stator core 600, thus ensuring the mating dimensions between the fourth protrusion 316 and the stator core 600 and effectively preventing the stator insulation end plate 10 from shifting relative to the stator core 600.

[0181] In some embodiments, the number of fourth protrusions 316 may be multiple.

[0182] Multiple fourth protrusions 316 are arranged at circumferential intervals along the stator 60.

[0183] In this embodiment, the number of fourth protrusions 316 and the location of the fourth protrusions 316 are further defined.

[0184] Specifically, there are multiple fourth protrusions 316, which are arranged at intervals along the circumference of the stator 60.

[0185] This configuration increases the area of ​​the stator's insulating end plate 10 that mates with the stator core 600. When winding the winding section 700, it reduces the probability of the stator's insulating end plate 10 tilting relative to the stator core 600, and reduces the probability of the stator's insulating end plate 10 shifting relative to the stator core 600. It ensures the mating dimensions of the stator core 600, the stator's insulating end plate 10, and the winding section 700, providing structural support for ensuring the mating dimensions of each component of the stator 60.

[0186] In some other embodiments, the number of fourth protrusions 316 is one.

[0187] In some embodiments, optionally, such as Figure 3 and Figure 4 As shown, the second axial end face 314 of the connecting section 310 is provided with a fifth protrusion 318.

[0188] The fifth protrusion 318 is used for the installation and positioning of the connecting section 310.

[0189] In this embodiment, the structure of the line-passing portion 300 is further defined.

[0190] Specifically, the second axial end face 314 of the connecting section 310 is provided with a fifth protrusion 318. That is, the connecting section 310 is provided with a fifth protrusion 318, which is located at the second axial end face 314 of the connecting section 310 and extends along the axial direction of the stator 60.

[0191] The third axial end face 610 of the stator core 600 is provided with a positioning hole 612. When the stator core 600 of the stator 60 is assembled with the insulating end plate 10 of the stator, the fifth protrusion 318 extends into the positioning hole 612 of the stator core 600. This arrangement increases the mating area between the stator core 600 and the insulating end plate 10 of the stator, ensuring the mating dimensions between the stator core 600 and the insulating end plate 10 of the stator. In this way, when winding the winding portion 700, the probability of the insulating end plate 10 of the stator tilting relative to the stator core 600 is reduced, the probability of the insulating end plate 10 of the stator shifting relative to the stator core 600 is reduced, and the mating dimensions of the stator core 600, the insulating end plate 10 of the stator, and the winding portion 700 are ensured, providing structural support for ensuring the mating dimensions of the various components of the stator 60.

[0192] In this application, there is one fifth protrusion 318 and one positioning hole 612 in the stator core 600.

[0193] In some other embodiments, there are multiple fifth protrusions 318 and multiple positioning holes 612. The multiple fifth protrusions 318 are arranged at intervals, and each fifth protrusion 318 is inserted into a positioning hole 612.

[0194] In some embodiments, optionally, such as Figure 4 As shown, the insulating end plate 10 of the stator also includes two limiting plates 400.

[0195] Along the axial direction of the stator 60, the blocking part 100, the winding part 200, and the passing part 300 are connected to the same side of the limiting plate 400.

[0196] Two limiting plates 400 are arranged at intervals around the stator 60 to enclose the iron core slot 500.

[0197] In this embodiment, the structure of the insulating end plate 10 of the stator is further defined.

[0198] Specifically, the insulating end plate 10 of the stator also includes two limiting plates 400, which are arranged at intervals along the circumference of the stator 60.

[0199] Any one of the blocking part 100, the winding part 200, and the passing part 300 is connected to the limiting plate 400, and along the axial direction of the stator 60, the blocking part 100, the winding part 200, and the passing part 300 are located on the same side of the limiting plate 400.

[0200] Specifically, the two limiting plates 400, the blocking part 100, the winding part 200 and the passing part 300 enclose the iron core slot 500.

[0201] When the stator core 600 of the stator 60 is assembled with the stator insulating end plate 10, a portion of the stator core 600 extends into the core slot 500. This arrangement increases the mating area between the stator core 600 and the stator insulating end plate 10, ensuring the mating dimensions between them. Thus, when winding the winding portion 700, the probability of the stator insulating end plate 10 tilting relative to the stator core 600 is reduced, as is the probability of displacement of the stator insulating end plate 10 relative to the stator core 600. This ensures the mating dimensions of the stator core 600, the stator insulating end plate 10, and the winding portion 700, providing structural support for ensuring the mating dimensions of all components of the stator 60.

[0202] Optionally, the limiting plate is arranged with a 400° bend.

[0203] Specifically, the limiting plate 400 includes a first limiting segment, a second limiting segment, and a third limiting segment, with the second limiting segment connecting the first and third limiting segments. The first limiting segment is connected to the outer edge of the connecting segment 310, the second limiting segment is connected to the outer edge of the winding portion 200, and the third limiting segment is connected to the blocking portion 100. This arrangement helps to enhance the structural strength and rigidity of the stator's insulating end plate 10. That is, while ensuring the assembly stability and reliability of the stator's insulating end plate 10 and the stator core 600, it can reduce the probability of deformation when the stator's insulating end plate 10 is wound with the winding portion 700, providing structural support for ensuring the external dimensions of the stator 60.

[0204] In some embodiments, optionally, such as Figure 4 As shown, the winding section 200 is provided with a clearance groove 210.

[0205] The clearance groove 210 is located between the two limit plates 400.

[0206] In this embodiment, the structure of the insulating end plate 10 of the stator is further defined.

[0207] Specifically, the axial end face of the winding section 200 is provided with a clearance groove 210. The clearance groove 210 and the limiting plate 400 are located on the same side of the winding section 200. The clearance groove 210 is located between the two limiting plates 400. The clearance groove 210 is used to avoid some structures of the stator core 600. For example, the clearance groove 210 is used to avoid the rivet portion of the stator core 600. This arrangement ensures the fit dimensions between the stator core 600 and the stator insulation end plate 10, preventing the stator insulation end plate 10 from being lifted and tilted by the stator core 600, and providing structural support to ensure the effective fit dimensions between the stator core 600 and the stator insulation end plate 10.

[0208] In addition, this structural configuration can enhance the structural strength and rigidity of the stator insulation end plate 10, reduce the probability of deformation when the stator insulation end plate 10 is wound with the winding portion 700, and provide structural support for ensuring the external dimensions of the stator 60.

[0209] Optionally, the fourth protrusion 316 is located on one side of the clearance groove 210 along the radial direction of the stator 60. For example, the fourth protrusion 316 is located on the outer side of the clearance groove 210 along the radial direction of the stator 60.

[0210] In some embodiments, optionally, such as Figure 2 As shown, the first circumferential end face 320 of the connecting section 310 has a notch 324.

[0211] The second circumferential end face 322 of the connecting section 310 is provided with a sixth protrusion 326.

[0212] In this embodiment, the structure of the connecting segment 310 is further defined.

[0213] Specifically, along the circumferential direction of the stator 60, the connecting segment 310 has a first circumferential end face 320 and a second circumferential end face 322 arranged opposite to each other and spaced apart. The first circumferential end face 320 of the connecting segment 310 is provided with a notch 324, and the second circumferential end face 322 of the connecting segment 310 is provided with a sixth protrusion 326.

[0214] The stator 60 includes multiple stator insulating end plates 10. When assembling the multiple stator insulating end plates 10, in two adjacent stator insulating end plates 10, the sixth protrusion 326 of one stator insulating end plate 10 is inserted into the notch 324 of the other stator insulating end plate 10. That is, the notch 324 of one stator insulating end plate 10 is used to allow the sixth protrusion 326 of the other stator insulating end plate 10 to be inserted. In this way, the mating dimensions of the multiple stator insulating end plates 10 can be guaranteed.

[0215] like Figure 6 and Figure 7 As shown, a stator 60 according to some embodiments of this application includes a stator core 600, a plurality of insulating end plates 10 of the stator in any of the above embodiments, and a winding portion 700.

[0216] Along the axial direction of the stator 60, the insulating end plates 10 of multiple stators are located on the same side of the stator core 600.

[0217] In the insulating end plates 10 of two adjacent stators, the sixth protrusion 326 of the insulating end plate 10 of one stator is inserted into the notch 324 of the insulating end plate 10 of the other stator.

[0218] The winding section 700 is wound around the stator core 600 through an insulating end plate.

[0219] In this embodiment, the stator 60 includes a stator core 600, multiple stator insulating end plates 10, and a winding section 700.

[0220] Along the axial direction of the stator 60, the insulating end plates 10 of multiple stators are located on the same side of the stator core 600.

[0221] In the insulating end plates 10 of two adjacent stators, the sixth protrusion 326 of the insulating end plate 10 of one stator is inserted into the notch 324 of the insulating end plate 10 of the other stator. That is, the notch 324 of the insulating end plate 10 of one stator is used to allow the sixth protrusion 326 of the insulating end plate 10 of the other stator to be inserted. In this way, the mating dimensions of the insulating end plates 10 of multiple stators can be guaranteed.

[0222] Since the stator 60 of this application includes the insulating end plate 10 of the stator in any of the above embodiments, it has all the beneficial effects of the insulating end plate 10 of the stator described above, which will not be described one by one here.

[0223] In some embodiments, optionally, such as Figure 5 As shown, the winding section 700 has a winding 710.

[0224] A portion of the winding 710 is disposed in the first conductor groove 380 and the second conductor groove 390.

[0225] When the inlet section 330 is provided with a second conductor groove 390, the minimum distance between the end faces of two adjacent second protrusions 334 of the stator insulation end plate 10 that are close to each other is greater than 1.5 times the outer diameter of the winding 710.

[0226] In this embodiment, the mating structure of the winding section 700 and the insulating end plate 10 of the stator is further defined.

[0227] The winding section 700 has a winding 710, a portion of which is disposed in the first conductor groove 380 and the second conductor groove 390. That is, the winding 710 of the winding section 700 is wound around the second conductor groove 390 of the lead-in section 330, and wound around the first conductor groove 380 of the lead-out section 340 via the wire groove 350. It is understandable that, along the radial direction of the stator 60, the first conductor slot 380 and the second conductor slot 390 are located on different sides of the wire-passing portion 300. In this way, when winding the winding 710 of the winding portion 700, the winding 710 can be tightly fitted to the first conductor slot 380 and the second conductor slot 390. That is, the winding 710 can be tightly fitted to the insulating end plate 10 of the stator. This can effectively prevent the winding 710 from falling off the insulating end plate 10 of the stator due to loosening, and can also effectively prevent the winding 710 from protruding in the radial direction of the stator 60 and being damaged. This is beneficial to reducing the material usage of the winding portion 700, reducing the production cost of the motor, reducing the copper loss of the motor, and improving the efficiency of the motor.

[0228] Furthermore, the minimum distance between the end faces of two adjacent second protrusions 334 on the stator's insulating end plate 10 is greater than 1.5 times the outer diameter of the winding 710. This defines the matching structure between the distance between two adjacent second protrusions 334 and the outer diameter of the winding 710. This ensures that the winding 710 can be completely placed within the second conductor groove 390 when the end wire passes through, preventing the winding 710 from slipping off and improving the insulation reliability of the motor.

[0229] Optionally, the minimum distance between two adjacent second protrusions 334 of the stator's insulating end plate 10 is equal to 1.8 times the outer diameter of the winding 710, the minimum distance between two adjacent second protrusions 334 of the stator's insulating end plate 10 is equal to 2 times the outer diameter of the winding 710, and the minimum distance between two adjacent second protrusions 334 of the stator's insulating end plate 10 is equal to 2.5 times the outer diameter of the winding 710, etc., which will not be listed here.

[0230] It is understandable that the outer diameter of the winding 710 refers to the maximum distance between any two points on the outer surface of the winding 710 along the radial direction of the winding 710.

[0231] In some embodiments, the minimum distance between the end faces of the inlet segment 330 and the outlet segment 340 that are close to each other is greater than four times the outer diameter of the winding 710.

[0232] In this embodiment, the mating structure of the winding section 700 and the insulating end plate 10 of the stator is further defined.

[0233] Specifically, the minimum distance between the end faces of the lead-in section 330 and the lead-out section 340 is greater than four times the outer diameter of the winding 710. Along the circumference of the stator 60, the end face of the lead-in section 330 facing the lead-out section 340 is the first end face, and the end face of the lead-out section 340 facing the lead-in section 330 is the second end face. The minimum distance between the first and second end faces is greater than four times the outer diameter of the winding 710. This arrangement ensures a smooth transition of the winding 710 from the lead-in section 330 to the lead-out section 340 during the winding process of the winding section 700, preventing excessive bending of the winding 710 (e.g., copper wire) that could damage the varnish film, thus improving the service life of the winding 710 and the insulation performance of the motor.

[0234] Optionally, the minimum distance between the end faces of the inlet segment 330 and the outlet segment 340 that are close to each other is equal to 4.2 times the outer diameter of the winding 710, the minimum distance between the end faces of the inlet segment 330 and the outlet segment 340 that are close to each other is equal to 4.5 times the outer diameter of the winding 710, the minimum distance between the end faces of the inlet segment 330 and the outlet segment 340 that are close to each other is equal to 4.8 times the outer diameter of the winding 710, the minimum distance between the end faces of the inlet segment 330 and the outlet segment 340 that are close to each other is equal to 5 times the outer diameter of the winding 710, and the minimum distance between the end faces of the inlet segment 330 and the outlet segment 340 that are close to each other is equal to 6 times the outer diameter of the winding 710, etc., which will not be listed here.

[0235] It is understandable that the outer diameter of the winding 710 refers to the maximum distance between any two points on the outer surface of the winding 710 along the radial direction of the winding 710.

[0236] In some embodiments, optionally, such as Figure 7 As shown, the third axial end face 610 of the stator core 600 is provided with a positioning hole 612.

[0237] The fifth protrusion 318 of the insulating end plate 10 of the stator is inserted into the positioning hole 612.

[0238] A portion of the teeth 620 of the stator core is inserted into the core slot 500.

[0239] In this embodiment, the mating structure of the stator core 600 and the stator insulating end plate 10 is further defined.

[0240] Specifically, the third axial end face 610 of the stator core 600 is provided with a positioning hole 612, and the insulating end plate 10 of the stator has a fifth protrusion 318.

[0241] When the stator core 600 of the stator 60 is assembled with the stator insulating end plate 10, the fifth protrusion 318 extends into the positioning hole 612 of the stator core 600. This arrangement increases the mating area between the stator core 600 and the stator insulating end plate 10, ensuring the mating dimensions between the stator core 600 and the stator insulating end plate 10. Thus, when winding the winding portion 700, the probability of the stator insulating end plate 10 tilting relative to the stator core 600 is reduced, as is the probability of the stator insulating end plate 10 shifting relative to the stator core 600. This ensures the mating dimensions of the stator core 600, the stator insulating end plate 10, and the winding portion 700, providing structural support for ensuring the mating dimensions of all components of the stator 60.

[0242] Specifically, when the stator core 600 of the stator 60 is assembled with the stator insulating end plate 10, a portion of the stator core 600 extends into the core slot 500. This arrangement increases the mating area between the stator core 600 and the stator insulating end plate 10, ensuring the mating dimensions between them. Thus, when winding the winding portion 700, the probability of the stator insulating end plate 10 tilting relative to the stator core 600 is reduced, as is the probability of displacement of the stator insulating end plate 10 relative to the stator core 600. This ensures the mating dimensions of the stator core 600, the stator insulating end plate 10, and the winding portion 700, providing structural support for ensuring the mating dimensions of all components of the stator 60.

[0243] like Figure 6 and Figure 7 As shown, an electric motor according to some embodiments of the present application includes: a stator 60 as described in any of the above embodiments.

[0244] The motor provided in this application includes a stator 60 as described in any of the above embodiments, and therefore has all the beneficial effects of the stator 60, which will not be described in detail here.

[0245] A compressor according to some embodiments of this application includes: a motor as described in the above embodiments.

[0246] The compressor provided in this application includes a motor as described in the above embodiments, and therefore has all the beneficial effects of the motor described above, which will not be described in detail here.

[0247] A vehicle according to some embodiments of the present application includes: a motor as described in the above embodiments; or a compressor as described in the above embodiments.

[0248] The vehicle provided in this application includes a motor as described in the above embodiments or a compressor as described in the above embodiments, and therefore has all the beneficial effects of the motor or compressor described above, which will not be described one by one here.

[0249] It is worth noting that the vehicle can be a new energy vehicle. New energy vehicles include pure electric vehicles, range-extended electric vehicles, hybrid electric vehicles, fuel cell electric vehicles, and hydrogen engine vehicles.

[0250] The vehicle can also be a gasoline-powered car.

[0251] Optionally, this application has a reasonable structure for the insulating end plate 10 of the stator, which can improve the insulation performance of the motor and improve the level of automated production of the motor.

[0252] Optionally, the stator 60 includes a stator core 600, a stator insulating end plate 10, and a winding portion 700. Along the axial direction of the stator 60, the insulating end plate 10 is disposed on one side of the stator core 600. The insulating end plate 10 includes a winding portion 200, a blocking portion 100, and a wire-passing portion 300. The winding portion 200 is wound with the winding wire 710 (e.g., a coil) of the winding portion 700. The wire-passing portion 300 includes an inlet section 330 and an outlet section 340. The inlet section 330 has a plurality of second protrusions 334, with adjacent second protrusions 334 enclosing a second conductor groove 390. The outlet section 340 has a plurality of first protrusions 344, with adjacent first protrusions 344 enclosing a first conductor groove 380. The second protrusions 334 are disposed away from the blocking portion 100, and the first protrusions 344 are disposed towards the blocking portion 100. Along the axial direction of the stator 60, the first protrusion 344 and the second protrusion 334 are at the same height. This arrangement allows the end wire to be routed through the inlet section 330 and outlet section 340 of the stator insulation end plate 10 after the winding 710 of one tooth of the stator core 600 is completed. This enables seamless connection between different coils using the same enameled wire, improves the insulation performance of the motor, reduces wire ends, and facilitates automated winding of the equipment.

[0253] The minimum distance between two adjacent second protrusions 334 on the guide section 330 is greater than 1.5 times the maximum outer diameter of a single enameled wire. This setting ensures that the enameled wire is completely placed within the second conductor groove 390 when the end wire passes through, preventing the enameled wire from slipping off and improving the insulation reliability of the motor.

[0254] The minimum spacing between the lead-in section 330 and the lead-out section 340 is greater than four times the maximum outer diameter of a single enameled wire. This arrangement ensures a smooth transition of the enameled wire from the lead-in section 330 to the lead-out section 340 during the winding process of the winding section 700, preventing damage to the enamel film caused by excessive bending of the copper wire, and thus improving the service life of the enameled wire and the insulation performance of the motor.

[0255] The wall of the first wire groove 380 is an arc-shaped wall, and / or the wall of the second wire groove 390 is an arc-shaped wall.

[0256] like Figure 5As shown, the enameled wire is led out from the lead-out section 340 through the wire groove 350 from the lead-in section 330, and then enters the next stator through the lead-in section 330 of the insulating end plate 10. This cycle allows the wire to pass through the end continuously without generating excess wire ends, improving motor reliability and facilitating automated production.

[0257] like Figure 5 As shown, the stator's insulating end plate 10 has three windings 710 (e.g., enameled wire) of different phases. These three enameled wires can be completely isolated by the first protrusion 344 and the second protrusion 334. The enameled wires are confined within the first conductor groove 380 and the second conductor groove 390. Electrical isolation between the enameled wires of different phases of the motor can be achieved without additional insulation protection, and the insulation performance is high.

[0258] The stator's insulating end plate 10 includes a blocking portion 100, a winding portion 200, and a wire-passing portion 300. The wire-passing portion 300 includes a connecting section 310, an inlet section 330, and an outlet section 340.

[0259] Along the radial direction of the stator 60, the blocking portion 100 and the wire-passing portion 300 are arranged opposite to each other and spaced apart. The winding portion 200 is connected between the connecting section 310 and the blocking portion 100. That is, the winding portion 200 is connected between the blocking portion 100 and the wire-passing portion 300. The blocking portion 100, the winding portion 200, and the wire-passing portion 300 enclose a winding groove, and a portion of the winding wire 710 of the stator 60 is wound in the winding groove.

[0260] The connecting section 310 has a first axial end face 312. The inlet section 330 is connected to the first axial end face 312 of the connecting section 310, and the outlet section 340 is also connected to the first axial end face 312. That is, along the axial direction of the stator 60, the inlet section 330 and the outlet section 340 are connected to the same side of the connecting section 310, and the inlet section 330 and the outlet section 340 are arranged at intervals in the circumferential direction of the stator 60. The inlet section 330, the outlet section 340, and the connecting section 310 enclose a wire groove 350.

[0261] Along the radial direction of the stator 60, the inlet section 330 has a first radial end face 360 ​​and a second radial end face 370 arranged opposite to each other and spaced apart, with the first radial end face 360 ​​being closer to the blocking portion 100 than the second radial end face 370. Along the radial direction of the stator 60, the outlet section 340 has a first radial end face 360 ​​and a second radial end face 370 arranged opposite to each other and spaced apart, with the first radial end face 360 ​​being closer to the blocking portion 100 than the second radial end face 370. Specifically, the first radial end face 360 ​​of one of the inlet section 330 and the outlet section 340 is provided with a first wire groove 380, and the second radial end face 370 of the other is provided with a second wire groove 390. That is, the first radial end face 360 ​​of the inlet section 330 is provided with a first wire groove 380, and the second radial end face 370 of the outlet section 340 is provided with a second wire groove 390. Alternatively, the second radial end face 370 of the inlet section 330 may be provided with a first guide groove 380, and the first radial end face 360 ​​of the outlet section 340 may be provided with a second guide groove 390. That is, one of the inlet section 330 and the outlet section 340 may be provided with a first guide groove 380, and the other may be provided with a second guide groove 390. In other words, along the radial direction of the stator 60, the first guide groove 380 and the second guide groove 390 are provided on different sides of the wire-passing portion 300, and the recess directions of the first guide groove 380 and the second guide groove 390 are different.

[0262] The first conductor groove 380 and the second conductor groove 390 are connected by a through groove 350. In this way, the winding 710 of the winding section 700 is first wound around the first conductor groove 380 or the second conductor groove 390 in the inlet section 330, and then wound around the second conductor groove 390 or the first conductor groove 380 in the outlet section 340 through the through groove 350. It is understandable that, along the radial direction of the stator 60, the first conductor slot 380 and the second conductor slot 390 are located on different sides of the wire-passing portion 300. In this way, when winding the winding 710 of the winding portion 700, the winding 710 can be tightly fitted to the first conductor slot 380 and the second conductor slot 390. That is, the winding 710 can be tightly fitted to the insulating end plate 10 of the stator. This can effectively prevent the winding 710 from falling off the insulating end plate 10 of the stator due to loosening, and can also effectively prevent the winding 710 from protruding in the radial direction of the stator 60 and being damaged. This is beneficial to reducing the material usage of the winding portion 700, reducing the production cost of the motor, reducing the copper loss of the motor, and improving the efficiency of the motor.

[0263] In addition, this configuration allows the end wire to be routed through the lead-in section 330 and lead-out section 340 of the winding section 300 after one tooth of the stator 60 is wound. This enables different coils of the winding section 700 to be connected without breaks through the same winding wire 710 (e.g., enameled wire). This is beneficial for improving the insulation performance of the motor, reducing wire ends, facilitating automated winding of the equipment, improving production efficiency, and reducing production costs.
