[0001] This invention relates to the field of motor technology, and more specifically, to an insulating frame, a stator assembly, and a motor. Background Technology
[0002] In related technologies, the stator assembly includes an insulating frame and a mounting base. When assembling the stator assembly, the insulating frame secures the wires, and a mounting base secures the cross-bracing wires. This setup results in a large number of wire-fixing structures being required, such as the insulating frame and mounting base, leading to high material consumption, complex assembly processes, and high production costs. Summary of the Invention
[0003] The present invention aims to solve at least one of the technical problems existing in the prior art or related art.
[0004] Therefore, a first aspect of the present invention provides an insulating frame.
[0005] A second aspect of the invention provides a stator assembly.
[0006] A third aspect of the present invention provides an electric motor.
[0007] In view of this, a first aspect of the present invention provides an insulating frame for a stator assembly, the stator assembly including windings, wires, a stator core and slot insulation, the insulating frame including: a mounting member along the axial direction of the stator assembly, the mounting member having a first end and a second end; a winding member disposed on the mounting member, the winding member having a fixing portion, at least a portion of the fixing portion protruding from the first end of the mounting member, the fixing portion for fixing the windings and wires; and a hanging member disposed on the mounting member, the hanging member having a hanging portion, the mounting member being located between the axis of the stator assembly and the hanging portion, and the hanging portion being located at the second end of the mounting member, the hanging portion for fixing the windings.
[0008] The present invention provides an insulating frame comprising a mounting component, a winding component, and a hanging component. Both the winding component and the hanging component are disposed on the mounting component, which serves to support and fix the winding component and the hanging component.
[0009] The winding component has a fixing part, at least a portion of which protrudes from the first end of the mounting component. The fixing part has the function of fixing the winding and the wire.
[0010] The hanging part is provided with a hanging part, which is located on the side of the mounting part away from the axis of the stator assembly. The hanging part has the function of fixing the winding.
[0011] In other words, the mounting components, winding components, and hanging components work together to simultaneously meet the needs of fixing wires and bridging steel windings. This enriches the functionality of the insulation frame, reduces material input, simplifies wire management, improves assembly efficiency, and helps reduce product production costs.
[0012] Understandably, since the mounting component is located between the axis of the stator assembly and the hanging part, it ensures the effectiveness and feasibility of fixing the winding in the hanging part without interfering with the rotor assembly of the motor, thus guaranteeing the normal use of the stator assembly.
[0013] Understandably, at least a portion of the fixing part protrudes from the first end of the mounting member, that is, it defines the mating structure of the fixing part and the mounting member, and provides assembly space for the fixing part to fix the winding and the wire.
[0014] Specifically, along the axial direction of the stator assembly, the mounting member has a first end and a second end. That is, the first end and the second end of the mounting member are correspondingly arranged in the axial direction of the stator assembly.
[0015] The insulating frame according to the present invention may also have the following additional technical features:
[0016] In the above technical solution, further, along the circumference of the stator assembly, the mounting component has a third end and a fourth end; both the third end and the fourth end are provided with a limiting structure, which is used to limit the stator core and slot insulation.
[0017] In this technical solution, the mounting member has a third end and a fourth end along the circumference of the stator assembly. That is, the third end and the fourth end of the mounting member are correspondingly arranged in the circumference of the stator assembly.
[0018] The mounting component has a limiting structure at its third end and a limiting structure at its fourth end. The limiting structures at the third and fourth ends work together to limit the stator core and slot insulation in the circumferential direction of the stator assembly, preventing the stator core and slot insulation from moving in the circumferential direction of the stator assembly. This provides effective and reliable structural support to ensure the fit dimensions of the stator core, insulation slots, and windings.
[0019] It is understandable that the limiting structure at the third end of the mounting component, together with the limiting structure at the fourth end of the mounting component, works on the stator core to achieve a tight fit.
[0020] It is understandable that the limiting structure at the third end of the mounting component cooperates with the limiting structure at the fourth end of the mounting component to act together on the slot insulation. The limiting structure is connected to the port of the slot insulation and controls the length of the slot insulation along the circumference of the stator assembly.
[0021] In any of the above technical solutions, the limiting structure further includes: a first protrusion extending axially along the stator assembly and used to fix the stator core; and a second protrusion connected to the first protrusion, extending axially along the stator assembly and extending at least a portion of the second protrusion circumferentially out of the outer surface of the first protrusion and used to fix the slot insulation.
[0022] In this technical solution, the limiting structure includes a first protrusion and a second protrusion, the second protrusion being connected to the first protrusion, and at least a portion of the second protrusion extending outward from the outer surface of the first protrusion along the circumferential direction of the stator assembly. That is, the first protrusion and the second protrusion together form a two-tiered trapezoidal structure.
[0023] Specifically, the first protrusion is used to engage with the stator core to limit the stator core circumferentially along the stator assembly.
[0024] Specifically, the second protrusion is used to engage with the slot insulation to limit the slot insulation along the circumferential direction of the stator assembly.
[0025] It is understandable that the first protrusion at the third end of the mounting component cooperates with the first protrusion at the fourth end of the mounting component to work together on the stator core and achieve a fastening fit.
[0026] Understandably, the second protrusion at the third end of the mounting component cooperates with the second protrusion at the fourth end of the mounting component to work together on the slot insulation. The second protrusion is connected to the port of the slot insulation and controls the length of the slot insulation along the circumference of the stator assembly.
[0027] In any of the above technical solutions, the limiting structure further includes a third protrusion; the third protrusion is disposed on the first protrusion, the third protrusion is closer to the stator core than the first protrusion, and the length of the third protrusion is less than the length of the first protrusion along the axial direction of the stator assembly; and / or the third protrusion is disposed on the second protrusion, the third protrusion is closer to the slot insulation than the second protrusion, and the length of the third protrusion is less than the length of the second protrusion along the axial direction of the stator assembly.
[0028] In this technical solution, the limiting structure also includes a third protrusion, which is disposed on one of the first and second protrusions. When the third protrusion is disposed on the first protrusion, the third protrusion is closer to the stator core than the first protrusion; when the third protrusion is disposed on the second protrusion, the third protrusion is closer to the slot insulation than the second protrusion.
[0029] Due to manufacturing and assembly errors, a mating structure between the first and third protrusions, and / or a mating structure between the second and third protrusions, is provided such that, along the axial direction of the stator assembly, the length of the third protrusion is less than the length of the first protrusion, and / or the length of the third protrusion is less than the length of the second protrusion. The third protrusion is used to connect with the stator core, and / or to the slot insulation, thus achieving a secure fit.
[0030] Specifically, the outer surface of the first protrusion includes a first wall and a second wall, both extending axially along the stator assembly. A first end of the first wall is connected to a mounting member, a second end of the first wall extends away from the mounting member, a third end of the second wall is connected to the second end of the first wall, and a fourth end of the second wall is connected to the mounting member. The included angle between the first and second walls is greater than or equal to 80° and less than or equal to 100°. For example, the included angle between the first and second walls includes 85°, 90°, 95°, 98°, etc., which are not listed here.
[0031] Specifically, the third protrusion is located at the junction of the first wall and the second wall.
[0032] Specifically, along the axial direction of the stator assembly, the third protrusion is located at the middle of the junction of the first and second walls.
[0033] Specifically, the outer surface of the second protrusion includes a third wall surface and a fourth wall surface, both extending axially along the stator assembly. The first end of the third wall surface is connected to the mounting component, the second end of the third wall surface extends in a direction away from the mounting component, the third end of the fourth wall surface is connected to the second end of the third wall surface, and the fourth end of the fourth wall surface is connected to the mounting component. The included angle formed by the third and fourth wall surfaces is greater than or equal to 80° and less than or equal to 100°. For example, the included angle formed by the third and fourth wall surfaces includes 85°, 90°, 95°, 98°, etc., which are not listed here.
[0034] Specifically, the third protrusion is located at the junction of the third wall and the fourth wall.
[0035] Specifically, along the axial direction of the stator assembly, the third protrusion is located at the middle of the connection between the third and fourth walls.
[0036] Specifically, the shape of the cross-section of the third convex part includes any of the following: semi-ellipse, semi-circle, trapezoid, etc., which will not be listed here.
[0037] Specifically, the protrusion height of the third protrusion is greater than or equal to 3mm and less than or equal to 8mm.
[0038] In any of the above technical solutions, the end face of the mounting component facing the axis of the stator assembly is an arc surface, and the distance from any two points on the arc surface to the axis of the stator core is equal.
[0039] In this technical solution, by rationally designing the structure of the mounting component, the end face of the mounting component facing the axis of the stator assembly is made into an arc surface, and the shape of the arc surface is further defined so that the distance from any two points on the arc surface to the axis of the stator core is equal. This design ensures that the mounting component will not interfere with the rotor assembly of the motor, guaranteeing effective cooperation between the rotor assembly and the stator assembly.
[0040] In any of the above technical solutions, the mounting component is further provided with a first wiring terminal hole, a second wiring terminal hole, and a protector terminal hole.
[0041] In this technical solution, by rationally designing the structure of the mounting component, it is equipped with a first terminal hole, a second terminal hole, and a protector terminal hole. In other words, the mounting component serves to assemble the terminal blocks and protector terminals. This means the insulating frame fulfills the requirement of fixing the protector, wires, and the windings of the cross-steel wire. Consequently, it enriches the functionality of the insulating frame, reduces material input, simplifies the wire management process, improves assembly efficiency, and helps reduce product production costs.
[0042] In any of the above technical solutions, the protector terminal hole is further located between the first terminal hole and the second terminal hole.
[0043] In this technical solution, by rationally setting the mating structure of the first terminal hole, the second terminal hole, and the protector terminal hole, the protector terminal hole is positioned between the first terminal hole and the second terminal hole. This ensures the effectiveness and feasibility of the mating connection between the mounting component and the terminals and protector terminals, while also facilitating wiring and simplifying the wiring process.
[0044] In any of the above technical solutions, the insulating frame further includes: a connecting rib, disposed on the side of the mounting member away from the axis of the stator assembly, and the connecting rib is connected to the winding member.
[0045] In this technical solution, the insulation frame also includes connecting ribs located on the side of the mounting component away from the axis of the stator assembly, and the connecting ribs are connected to the winding components. That is, the mounting component and the winding components are connected together by the connecting ribs. This arrangement enhances the overall structural strength of the mounting component and the winding components, effectively preventing deformation of the insulation frame, and thus ensuring the proper fit between the insulation frame and the stator core, windings, and slot insulation.
[0046] Specifically, along the radial direction of the stator assembly, the thickness of the connecting ribs is greater than or equal to 6 mm and less than or equal to 10 mm. For example, 7 mm, 8 mm, 9 mm, etc., are not listed here.
[0047] In any of the above technical solutions, the connecting rib, mounting component, winding component, and hanging component are further integrated into one piece.
[0048] In this technical solution, by rationally designing the cooperative structure of the connecting ribs, mounting components, winding components, and hanging components, they are integrated into a single unit. This structural design eliminates the assembly process for the connecting ribs, mounting components, winding components, and hanging components, thus simplifying the assembly and subsequent disassembly processes, improving assembly and disassembly efficiency, and consequently reducing production and maintenance costs. Furthermore, the integrated connection of the connecting ribs, mounting components, winding components, and hanging components ensures the dimensional accuracy requirements of the product.
[0049] In any of the above technical solutions, the connecting rib extends along the axial direction of the stator assembly, the connecting rib is arranged at intervals with the wire hanging part, and the side of the connecting rib away from the winding member is provided with a recess; along the circumference of the stator assembly, the recess is located on one side of the wire hanging part.
[0050] In this technical solution, by rationally designing the structure of the connecting ribs, a recess is provided on the side of the connecting rib facing away from the winding component. The connecting ribs and the wire-hanging part are arranged at intervals, and the recess is located on one side of the wire-hanging part along the circumference of the stator assembly. That is, along the axial direction of the stator assembly, there is a gap between the recess and the wire-hanging part, and along the circumference of the stator assembly, the recess is located on one side of the wire-hanging part. In other words, the recess and the wire-hanging part are staggered. When the winding is fixed using the connecting part, the recess has a guiding function and will not interfere with the coil of the winding. This can meet the wire-hanging movement trajectory requirements of the manipulator of the wire-hanging equipment, and smoothly and without damage complete the wire transition between windings.
[0051] In any of the above technical solutions, the hanging part further includes a hook, and the number of hanging parts is multiple, with the multiple hanging parts arranged at intervals along the circumference of the stator assembly.
[0052] In this technical solution, there are multiple hanging parts, and each hanging part includes hooks. That is, there are multiple hooks, which are arranged at intervals along the circumference of the stator assembly. This arrangement, while ensuring the hanging requirements, helps to reduce the material input for hanging parts, thereby reducing the production cost and weight of the product.
[0053] In any of the above technical solutions, further, the plurality of hanging parts include at least a first hanging part, a second hanging part, and a third hanging part. Along the circumferential direction of the stator assembly, the first hanging part is located between the second hanging part and the third hanging part. Along the circumferential direction of the stator assembly, the width of the second hanging part and the width of the third hanging part are both smaller than the width of the first hanging part.
[0054] In this technical solution, multiple hanging sections are categorized, including at least a first hanging section, a second hanging section, and a third hanging section. Along the circumference of the stator assembly, the first hanging section is located between the second and third hanging sections, and the widths of both the second and third hanging sections are smaller than the width of the first hanging section. Because the windings connected to the hanging section in the middle have a greater weight, the wider first hanging section is positioned in the middle, while the narrower second and third hanging sections are located around its periphery. This rationally arranges the distribution structure of the first, second, and third hanging sections, ensuring the hanging requirements are met while reducing material input for the hanging sections, thus lowering production costs and reducing product weight.
[0055] In any of the above technical solutions, the insulating frame further includes: a reinforcing rib extending from the hanging wire portion to the mounting component.
[0056] In this technical solution, the insulation frame also includes reinforcing ribs that extend from the wire hanging part to the mounting part. This feature enhances the overall structural strength and rigidity of the mounting part and the wire hanging part. As a result, the wire hanging part can withstand a certain mechanical force without deformation or damage during the wire hanging process, and can effectively prevent the insulation frame from deforming. This, in turn, ensures the fit dimensions between the insulation frame and the stator core, windings, and slot insulation.
[0057] In any of the above technical solutions, there are multiple connecting ribs, with each hanging part cooperating with one connecting rib.
[0058] In this technical solution, by reasonably setting up a cooperative structure of multiple connecting ribs and multiple hanging parts, each hanging part cooperates with a connecting rib. This setting has a guide and a recess at each hanging part, which helps to improve the winding efficiency.
[0059] In any of the above technical solutions, the fixing part further includes: a first clip for fixing at least one of the coil of the winding and the terminal block; and a second clip for fixing the wire.
[0060] In this technical solution, the fixing part includes a first clip and a second clip, which have different functions. Specifically, the first clip is used to fix at least one of the coil of the winding and the terminal, and the second clip is used to fix the wire. That is to say, the fixing part has the function of fixing the winding and the wire.
[0061] The first and second clips have different functions, so there will be no wiring confusion caused by the winding and wires sharing a single clip.
[0062] In any of the above technical solutions, the number of first clips is two, and the second clip is located between the two first clips along the circumference of the stator assembly.
[0063] In this technical solution, by rationally defining the mating structure of two first clips and one second clip, the second clip is positioned between the two first clips. This rational layout of the winding and wire mating positions simplifies the wire management process, improves assembly efficiency, and reduces product production costs.
[0064] In any of the above technical solutions, a positioning groove is further provided on the side of the winding member facing the hanging part, and the positioning groove is used to limit the insulation of the groove along the axial direction of the stator assembly.
[0065] In this technical solution, a positioning groove is provided on the side of the winding component facing the hanging part. The positioning groove serves to limit the slot insulation, ensuring the installation position of the slot insulation. Specifically, the positioning groove is used to limit the slot insulation along the axial direction of the stator assembly. This prevents the slot insulation from damaging the winding and also reduces the thickness of the winding component, effectively preventing shrinkage and deformation of the insulation frame during injection molding due to excessive thickness of the winding component.
[0066] In any of the above technical solutions, the insulation frame further includes: a first wire protector; a second wire protector, both the first and second wire protectors being connected to a winding member, and the winding member being located between the first and second wire protectors along the circumferential direction of the stator assembly; wherein the first and second wire protectors both extend along the circumferential direction of the stator assembly.
[0067] In this technical solution, the insulation frame also includes a first wire protector and a second wire protector. The winding member is located between the first and second wire protectors along the circumference of the stator assembly. Both the first and second wire protectors extend circumferentially along the stator assembly. The shapes of the first and second wire protectors are adapted to the shape of the winding coil. The first and second wire protectors protect the winding and prevent external forces from directly acting on the winding, thus avoiding winding damage.
[0068] In any of the above technical solutions, the insulating frame further includes: a first connector, the first wire protector and the winding member are connected by the first connector; a second connector, the second wire protector and the winding member are connected by the second connector; wherein the first connector and the second connector are both arranged in a bent manner.
[0069] In this technical solution, the insulating frame also includes a first connector and a second connector. The first wire protector and the winding member are connected by the first connector, and the second wire protector and the winding member are connected by the second connector.
[0070] Since both the first and second connectors are arranged in a bent manner, the structural strength can be enhanced, and the probability of deformation of the insulation frame can be effectively reduced.
[0071] In any of the above technical solutions, the first wire protector, the first connector, and the winding member are combined to form a first wire protector groove; the second wire protector, the second connector, and the winding member are combined to form a second wire protector groove.
[0072] In this technical solution, by rationally setting the cooperative structure of the first wire protector, the first connector, and the winding component, the first wire protector, the first connector, and the winding component are combined to form a first wire protector groove. Specifically, the opening and bottom of the first wire protector groove are arranged opposite each other along the axial direction of the stator assembly. This arrangement reduces material waste, avoids shrinkage and deformation of the insulation frame, and provides a safe position for the wiring of the equipment.
[0073] Furthermore, by rationally configuring the cooperation structure of the second wire guard, the second connector, and the winding component, the second wire guard, the second connector, and the winding component are combined to form a second wire guard groove. Specifically, the opening and bottom of the second wire guard groove are arranged opposite each other along the axial direction of the stator assembly. This configuration reduces material waste, avoids shrinkage and deformation of the insulation frame, and provides a safe location for equipment wiring.
[0074] A second aspect of the invention provides a stator assembly comprising an insulating frame as described in any of the technical solutions in the first aspect.
[0075] The stator assembly provided by the present invention has all the beneficial effects of the above-mentioned insulating frame because it includes the insulating frame of any of the technical solutions in the first aspect, which will not be described in detail here.
[0076] A third aspect of the invention provides an electric motor comprising: an insulating frame as described in any of the technical solutions in the first aspect, or a stator assembly as described in the second aspect.
[0077] The motor provided by the present invention has all the beneficial effects of the above-mentioned insulating frame or stator assembly because it includes an insulating frame as in any of the technical solutions in the first aspect or a stator assembly as in the second aspect, which will not be described in detail here.

Detailed Implementation
[0096] To better understand the above-mentioned objectives, features, and advantages of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.
[0097] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and therefore the scope of protection of the invention is not limited to the specific embodiments disclosed below.
[0098] The following reference Figures 1 to 14 An insulating frame 100, a stator assembly 300, and a motor are described according to some embodiments of the present invention.
[0099] Example 1:
[0100] like Figure 1 and Figure 2 As shown, an embodiment of the first aspect of the present invention provides an insulating frame 100 for a stator assembly 300, the stator assembly 300 including a winding 310, wires, a stator core 330 and slot insulation 350, and the insulating frame 100 including a mounting member 110, a winding member 130 and a hanging member 140.
[0101] Along the axial direction of the stator assembly 300, the mounting member 110 has a first end and a second end.
[0102] The winding member 130 is provided on the mounting member 110. The winding member 130 is provided with a fixing part 132. At least a portion of the fixing part 132 protrudes from the first end 112 of the mounting member. The fixing part 132 is used to fix the winding 310 and the wire.
[0103] The hanging member 140 is provided on the mounting member 110. The hanging member 140 has a hanging part. The mounting member 110 is located between the axis of the stator assembly 300 and the hanging part, and the hanging part is located at the second end 114 of the mounting member. The hanging part is used to fix the winding 310.
[0104] In detail, the insulating frame 100 includes a mounting member 110, a winding member 130, and a hanging member 140. The winding member 130 and the hanging member 140 are both disposed on the mounting member 110, and the mounting member 110 has the function of supporting and fixing the winding member 130 and the hanging member 140.
[0105] The winding member 130 is provided with a fixing part 132, at least a portion of which protrudes from the first end 112 of the mounting member. The fixing part 132 has the function of fixing the winding 310 and the wire.
[0106] The hanging part 140 is provided with a hanging part, which is located on the side of the mounting part 110 away from the axis of the stator assembly 300. The hanging part has the function of fixing the winding 310.
[0107] In other words, the mounting component 110, the winding component 130, and the hanging component 140 work together to simultaneously meet the needs of fixing the wire and the winding 310 that crosses the steel wire. This enriches the functionality of the insulation frame 100, reduces material input, simplifies the wire management process, improves assembly efficiency, and helps reduce product production costs.
[0108] Understandably, since the mounting component 110 is located between the axis of the stator assembly 300 and the hanging part, it ensures the effectiveness and feasibility of fixing the winding 310 in the hanging part without interfering with the rotor assembly of the motor, thus ensuring the normal use of the stator assembly 300.
[0109] Understandably, at least a portion of the fixing part 132 protrudes from the first end 112 of the mounting member, that is, it defines the mating structure of the fixing part 132 and the mounting member 110, providing assembly space for the fixing part 132 to fix the winding 310 and the wire.
[0110] Specifically, along the axial direction of the stator assembly 300, the mounting member 110 has a first end and a second end. That is, the first end 112 and the second end of the mounting member are correspondingly disposed in the axial direction of the stator assembly 300.
[0111] Example 2:
[0112] like Figure 1 and Figure 2 As shown, based on Embodiment 1, Embodiment 2 provides an insulating frame 100 for a stator assembly 300. The stator assembly 300 includes a winding 310, wires, a stator core 330, and slot insulation 350. The insulating frame 100 includes a mounting member 110, a winding member 130, and a hanging member 140.
[0113] Along the axial direction of the stator assembly 300, the mounting member 110 has a first end and a second end.
[0114] The winding member 130 is provided on the mounting member 110. The winding member 130 is provided with a fixing part 132. At least a portion of the fixing part 132 protrudes from the first end 112 of the mounting member. The fixing part 132 is used to fix the winding 310 and the wire.

[0116] Furthermore, such as Figure 2 As shown, along the circumference of the stator assembly 300, the mounting member 110 has a third end and a fourth end; both the third end and the fourth end are provided with a limiting structure 160, which is used to limit the stator core 330 and the slot insulation 350.
[0117] Specifically, along the circumferential direction of the stator assembly 300, the mounting member 110 has a third end and a fourth end. That is, the third end and the fourth end of the mounting member 110 are correspondingly provided in the circumferential direction of the stator assembly 300.
[0118] The third end of the mounting component 110 is provided with a limiting structure 160, and the fourth end of the mounting component 110 is also provided with a limiting structure 160. The limiting structures 160 at the third end and the limiting structures 160 at the fourth end cooperate to limit the stator core 330 and slot insulation 350 in the circumferential direction of the stator assembly 300, so that the stator core 330 and slot insulation 350 will not move in the circumferential direction of the stator assembly 300, providing effective and reliable structural support for ensuring the matching dimensions of the stator core 330, the insulating slot and the winding 310.
[0119] It is understandable that the limiting structure 160 at the third end of the mounting component 110 cooperates with the limiting structure 160 at the fourth end of the mounting component 110 to work together on the stator core 330 to achieve a fastening fit.
[0120] It is understood that the limiting structure 160 at the third end of the mounting member 110 cooperates with the limiting structure 160 at the fourth end of the mounting member 110 to act together on the slot insulation 350. The limiting structure 160 is connected to the port of the slot insulation 350 and controls the length of the slot insulation 350 along the circumference of the stator assembly 300.

[0127] Furthermore, such as Figure 2 and Figure 3 As shown, the limiting structure 160 includes a first protrusion 162 and a second protrusion 164.
[0128] The first protrusion 162 extends along the axial direction of the stator assembly 300 and is used to fix the stator core 330.
[0129] The second protrusion 164 is connected to the first protrusion 162. The second protrusion 164 extends along the axial direction of the stator assembly 300. At least a portion of the second protrusion 164 extends out of the outer surface of the first protrusion 162 along the circumferential direction of the stator assembly 300. The second protrusion 164 is used to fix the slot insulation 350.

That is, the first protrusion 162 and the second protrusion 164 together form a two-step trapezoidal structure.
[0131] Specifically, the first protrusion 162 is used to engage with the stator core 330 to limit the stator core 330 in the circumferential direction of the stator assembly 300.
[0132] Specifically, the second protrusion 164 is used to engage with the slot insulation 350 to limit the slot insulation 350 circumferentially along the stator assembly 300.

[0135] Specifically, the first protrusion engages with the root of the third inner groove 337 and the root of the fourth inner groove 338.
[0136] Furthermore, such as Figure 2 and Figure 3 As shown, the limiting structure 160 also includes a third protrusion 166.
[0137] The third protrusion 166 is disposed on the first protrusion 162. The third protrusion 166 is closer to the stator core 330 than the first protrusion 162. Along the axial direction of the stator assembly 300, the length of the third protrusion 166 is less than the length of the first protrusion 162.
[0138] And / or a third protrusion 166 is provided on the second protrusion 164, the third protrusion 166 being closer to the slot insulation 350 than the second protrusion 164, and the length of the third protrusion 166 being less than the length of the second protrusion 164 along the axial direction of the stator assembly 300.
[0139] The limiting structure 160 further includes a third protrusion 166, which is disposed on one of the first protrusion 162 and the second protrusion 164. When the third protrusion 166 is disposed on the first protrusion 162, the third protrusion 166 is closer to the stator core 330 than the first protrusion 162; when the third protrusion 166 is disposed on the second protrusion 164, the third protrusion 166 is closer to the slot insulation 350 than the second protrusion 164.
[0140] Due to manufacturing and assembly errors, a mating structure is provided between the first protrusion 162 and the third protrusion 166, and / or between the second protrusion 164 and the third protrusion 166, such that along the axial direction of the stator assembly 300, the length of the third protrusion 166 is less than the length of the first protrusion 162, and / or the length of the third protrusion 166 is less than the length of the second protrusion 164. The third protrusion 166 is used to connect with the stator core 330, and / or to connect with the slot insulation 350, thus achieving a secure fit.
[0141] Specifically, the outer surface of the first protrusion 162 includes a first wall and a second wall. Both the first and second walls extend axially along the stator assembly 300. A first end of the first wall is connected to the mounting member 110, a second end of the first wall extends in a direction away from the mounting member 110, a third end of the second wall is connected to the second end of the first wall, and a fourth end of the second wall is connected to the mounting member 110.

[0149] Example 4:
[0150] like Figure 1 and Figure 2 As shown, based on any of the embodiments in Embodiments 1 to 3, Embodiment 4 provides an insulating frame 100 for a stator assembly 300. The stator assembly 300 includes a winding 310, wires, a stator core 330, and slot insulation 350. The insulating frame 100 includes a mounting member 110, a winding member 130, and a hanging member 140.
[0151] Along the axial direction of the stator assembly 300, the mounting member 110 has a first end and a second end.
[0152] The winding member 130 is provided on the mounting member 110. The winding member 130 is provided with a fixing part 132. At least a portion of the fixing part 132 protrudes from the first end 112 of the mounting member. The fixing part 132 is used to fix the winding 310 and the wire.
[0153] The hanging member 140 is provided on the mounting member 110. The hanging member 140 has a hanging part. The mounting member 110 is located between the axis of the stator assembly 300 and the hanging part, and the hanging part is located at the second end 114 of the mounting member. The hanging part is used to fix the winding 310.
[0154] Furthermore, such as Figure 2 and Figure 7 As shown, the end face of the mounting component 110 facing the axis of the stator assembly 300 is an arc surface 116, and any two points on the arc surface 116 are equidistant from the axis of the stator core 330.
[0155] In detail, by rationally designing the structure of the mounting component 110, the end face of the mounting component 110 facing the axis of the stator assembly 300 is an arc surface 116, and the shape of the arc surface 116 is further defined so that the distance from any two points on the arc surface 116 to the axis of the stator core 330 is equal. This design ensures that the mounting component 110 will not interfere with the rotor assembly of the motor, thus guaranteeing effective cooperation between the rotor assembly and the stator assembly 300.
[0156] Specifically, along the radial direction of the stator assembly 300, the thickness of the mounting member 110 is greater than or equal to 3 mm and less than or equal to 5 mm. For example, the thickness includes 3.5 mm, 4 mm, 4.5 mm, etc., which will not be listed here.

[0158] Example 5:
[0159] like Figure 1 and Figure 2 As shown, based on any of the above embodiments, Embodiment 5 provides an insulating frame 100 for a stator assembly 300. The stator assembly 300 includes a winding 310, wires, a stator core 330, and slot insulation 350. The insulating frame 100 includes a mounting member 110, a winding member 130, and a hanging member 140.
[0160] Along the axial direction of the stator assembly 300, the mounting member 110 has a first end and a second end.
[0161] The winding member 130 is provided on the mounting member 110. The winding member 130 is provided with a fixing part 132. At least a portion of the fixing part 132 protrudes from the first end 112 of the mounting member. The fixing part 132 is used to fix the winding 310 and the wire.
[0162] The hanging member 140 is provided on the mounting member 110. The hanging member 140 has a hanging part. The mounting member 110 is located between the axis of the stator assembly 300 and the hanging part, and the hanging part is located at the second end 114 of the mounting member. The hanging part is used to fix the winding 310.
[0163] Furthermore, such as Figure 2 As shown, the mounting component 110 is provided with a first terminal hole 118, a second terminal hole 120 and a protector terminal hole 122.
[0164] In detail, by rationally designing the structure of the mounting component 110, it is provided with a first terminal hole 118, a second terminal hole 120, and a protector terminal hole 122. That is, the mounting component 110 serves to assemble the terminals and protector terminals. In other words, the insulating frame 100 meets the requirements for fixing the protector, wires, and the winding 310 of the cross-steel winding. This enriches the functionality of the insulating frame 100, reduces material input, simplifies the wire management process, improves assembly efficiency, and reduces product production costs.
[0165] Furthermore, such as Figure 2As shown, the protector terminal hole 122 is located between the first terminal hole 118 and the second terminal hole 120.
[0166] Specifically, by rationally setting the mating structure of the first terminal hole 118, the second terminal hole 120, and the protector terminal hole 122, the protector terminal hole 122 is positioned between the first terminal hole 118 and the second terminal hole 120. This ensures the effectiveness and feasibility of the mating connection between the mounting component 110 and the terminals and protector terminals, while also facilitating wiring and simplifying the wiring process.
[0167] Example 6:
[0168] like Figure 1 and Figure 2 As shown, based on any of the above embodiments, Embodiment 6 provides an insulating frame 100 for a stator assembly 300. The stator assembly 300 includes a winding 310, wires, a stator core 330, and slot insulation 350. The insulating frame 100 includes a mounting member 110, a winding member 130, and a hanging member 140.
[0169] Along the axial direction of the stator assembly 300, the mounting member 110 has a first end and a second end.
[0170] The winding member 130 is provided on the mounting member 110. The winding member 130 is provided with a fixing part 132. At least a portion of the fixing part 132 protrudes from the first end 112 of the mounting member. The fixing part 132 is used to fix the winding 310 and the wire.
[0171] The hanging member 140 is provided on the mounting member 110. The hanging member 140 has a hanging part. The mounting member 110 is located between the axis of the stator assembly 300 and the hanging part, and the hanging part is located at the second end 114 of the mounting member. The hanging part is used to fix the winding 310.
[0172] Furthermore, such as Figure 1 and Figure 4 As shown, the insulating frame 100 also includes a connecting rib 170, which is located on the side of the mounting member 110 away from the axis of the stator assembly 300, and the connecting rib 170 is connected to the winding member 130.
[0173] In detail, the insulating frame 100 also includes a connecting rib 170, which is located on the side of the mounting member 110 opposite to the axis of the stator assembly 300, and is connected to the winding member 130. That is, the mounting member 110 and the winding member 130 are connected together by the connecting rib 170. This arrangement can enhance the overall structural strength of the mounting member 110 and the winding member 130, effectively prevent the insulating frame 100 from deforming, and thus ensure the fit dimensions of the insulating frame 100 with the stator core 330, the winding 310, and the slot insulation 350.
[0174] Furthermore, the connecting rib 170, the mounting component 110, the winding component 130, and the hanging component 140 are integrally formed.
[0175] By rationally designing the cooperative structure of the connecting rib 170, mounting component 110, winding component 130, and hanging component 140, these components are integrally formed. This structural design eliminates the assembly process of the connecting rib 170, mounting component 110, winding component 130, and hanging component 140, thus simplifying the assembly and subsequent disassembly processes. This improves assembly and disassembly efficiency and reduces production and maintenance costs. Furthermore, the integral connection of the connecting rib 170, mounting component 110, winding component 130, and hanging component 140 ensures the dimensional accuracy requirements of the product.
[0176] Furthermore, such as Figure 4 As shown, the connecting rib 170 extends along the axial direction of the stator assembly 300. The connecting rib 170 is arranged at intervals with the wire hanging part. The connecting rib 170 has a recess 172 on the side away from the winding member 130. Along the circumference of the stator assembly 300, the recess 172 is located on one side of the wire hanging part.
[0177] In detail, by rationally setting the structure of the connecting rib 170, a recess 172 is provided on the side of the connecting rib 170 away from the winding member 130. The connecting rib 170 and the wire hanging part are arranged at intervals, and the recess 172 is located on one side of the wire hanging part in the circumferential direction of the stator assembly 300. That is, along the axial direction of the stator assembly 300, there is a gap between the recess 172 and the wire hanging part, and along the circumferential direction of the stator assembly 300, the recess 172 is located on one side of the wire hanging part. In other words, the recess 172 is staggered from the wire hanging part. When the winding 310 is fixed by the hanging part, the recess 172 has a guiding function and will not interfere with the coil of the winding 310. This can meet the wire hanging movement trajectory requirements of the wire hanging equipment robot and smoothly and without damage complete the wire transition between windings 310.
[0178] Specifically, the shape of the recess 172 includes any of the following: semi-circular, semi-elliptical, inverted trapezoidal, semi-rhomboid, etc., which will not be listed here.
[0179] For example, the recess 172 is semi-circular in shape, which can reduce the probability of damage to the coil of winding 310.
[0180] Example 7:
[0181] like Figure 1 and Figure 2As shown, based on the above embodiment 6, embodiment 7 provides an insulating frame 100 for stator assembly 300. The stator assembly 300 includes winding 310, wires, stator core 330 and slot insulation 350. The insulating frame 100 includes mounting member 110, winding member 130 and hanging member 140.
[0182] Along the axial direction of the stator assembly 300, the mounting member 110 has a first end and a second end.
[0183] The winding member 130 is provided on the mounting member 110. The winding member 130 is provided with a fixing part 132. At least a portion of the fixing part 132 protrudes from the first end 112 of the mounting member. The fixing part 132 is used to fix the winding 310 and the wire.
[0184] The hanging member 140 is provided on the mounting member 110. The hanging member 140 has a hanging part. The mounting member 110 is located between the axis of the stator assembly 300 and the hanging part, and the hanging part is located at the second end 114 of the mounting member. The hanging part is used to fix the winding 310.
[0185] The insulating frame 100 also includes a connecting rib 170, which is located on the side of the mounting member 110 away from the axis of the stator assembly 300, and the connecting rib 170 is connected to the winding member 130.
[0186] Furthermore, such as Figure 5 As shown, the hanging part includes a hook 148, and there are multiple hanging parts, which are arranged at intervals along the circumference of the stator assembly 300.
[0187] In detail, there are multiple hanging parts, and each hanging part includes hooks 148. That is, there are multiple hooks 148, which are arranged at intervals along the circumference of the stator assembly 300. This arrangement ensures the hanging requirements while reducing the material input for hanging parts 140, thereby reducing the production cost and weight of the product.
[0188] Furthermore, such as Figure 1 and Figure 4 As shown, the multiple hanging parts include at least a first hanging part 142, a second hanging part 144, and a third hanging part 146.
[0189] Along the circumferential direction of the stator assembly 300, the first wire-hanging portion 142 is located between the second wire-hanging portion 144 and the third wire-hanging portion 146.
[0190] Along the circumference of the stator assembly 300, the width of the second wire-hanging portion 144 and the width of the third wire-hanging portion 146 are both smaller than the width of the first wire-hanging portion 142.
[0191] The design categorizes multiple hanging sections, including at least a first hanging section 142, a second hanging section 144, and a third hanging section 146. Along the circumference of the stator assembly 300, the first hanging section 142 is located between the second hanging section 144 and the third hanging section 146, with both the width of the second hanging section 144 and the width of the third hanging section 146 being smaller than the width of the first hanging section 142. Because the winding 310 connected to the middle hanging section has a greater weight, the wider first hanging section 142 is positioned in the middle, while the narrower second hanging section 144 and the third hanging section 146 are located around its periphery. This optimized layout of the first hanging section 142, the second hanging section 144, and the third hanging section 146 reduces material input for the hanging sections while ensuring the hanging requirements are met, thus lowering production costs and product weight.
[0192] Furthermore, such as Figure 1 and Figure 4 As shown, the insulating frame 100 also includes a reinforcing rib 180, which extends from the wire hanging portion to the mounting member 110.
[0193] The insulating frame 100 also includes a reinforcing rib 180, which extends from the wire hanging part to the mounting part 110. This arrangement can enhance the overall structural strength and hardness of the mounting part 110 and the wire hanging part. In this way, the wire hanging part can withstand a certain mechanical force without deformation or damage during the wire hanging process, and can effectively prevent the insulating frame 100 from deforming. This can ensure the fit dimensions between the insulating frame 100 and the stator core 330, winding 310 and slot insulation 350.
[0194] Specifically, the reinforcing rib 180 extends from the first hanging part 142 to the mounting part 110.
[0195] Specifically, there are multiple reinforcing ribs 180, which are arranged at circumferential intervals along the stator assembly 300.
[0196] Furthermore, there are multiple connecting ribs 170, with each hanging part cooperating with one connecting rib 170.
[0197] In particular, by reasonably setting up a cooperative structure of multiple connecting ribs 170 and multiple hanging parts, each hanging part cooperates with a connecting rib 170. Each hanging part has a guide and a recess 172, which helps to improve the winding efficiency.
[0198] Example 8:
[0199] like Figure 1 and Figure 2As shown, based on any of the above embodiments, Embodiment 8 provides an insulating frame 100 for a stator assembly 300. The stator assembly 300 includes a winding 310, wires, a stator core 330, and slot insulation 350. The insulating frame 100 includes a mounting member 110, a winding member 130, and a hanging member 140.
[0200] Along the axial direction of the stator assembly 300, the mounting member 110 has a first end and a second end.
[0201] The winding member 130 is provided on the mounting member 110. The winding member 130 is provided with a fixing part 132. At least a portion of the fixing part 132 protrudes from the first end 112 of the mounting member. The fixing part 132 is used to fix the winding 310 and the wire.
[0202] The hanging member 140 is provided on the mounting member 110. The hanging member 140 has a hanging part. The mounting member 110 is located between the axis of the stator assembly 300 and the hanging part, and the hanging part is located at the second end 114 of the mounting member. The hanging part is used to fix the winding 310.
[0203] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, the fixing part 132 includes a first buckle 134 and a second buckle 136.
[0204] The first clip 134 is used to secure at least one of the coil and the terminal of the winding 310.
[0205] The second clip 136 is used to secure the wire.
[0206] In detail, the fixing part 132 includes a first latch 134 and a second latch 136, which have different functions. Specifically, the first latch 134 is used to fix at least one of the coil and the terminal of the winding 310, and the second latch 136 is used to fix the wire. That is, the fixing part 132 has the function of fixing the winding 310 and the wire.
[0207] The first clip 134 and the second clip 136 have different functions, so the wiring will not be messy because the winding 310 and the wire share a clip.
[0208] Furthermore, such as Figure 1 , Figure 2 and Figure 4 As shown, there are two first latches 134 along the circumference of the stator assembly 300, and a second latch 136 is located between the two first latches 134.
[0209] Specifically, by rationally defining the mating structure of the two first clips 134 and the second clip 136, the second clip 136 is positioned between the two first clips 134. This rational layout of the mating positions of the winding 310 and the wire simplifies the wire management process, improves assembly efficiency, and helps reduce product production costs.
[0210] Specifically, the first latch 134 includes a latch body and a mating part. The mating part is located on one side of the latch body along the radial direction of the stator assembly 300, and the latch body and the mating part together form a U-shaped structure.
[0211] Specifically, such as Figure 6 As shown, the second latch 136 includes a first latch 134 and a second latch 136, arranged at intervals along the circumference of the stator assembly 300. The end of the first latch 134 facing away from the second latch 136 is a first end face 137, and the end of the second latch 136 facing away from the first latch 134 is a second end face 138. The included angle k1 between the first end face 137 and the second end face 138 is greater than 0° and less than or equal to 10°. For example, the included angle k1 between the first end face 137 and the second end face 138 includes 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, and 9°, etc., which are not listed here.
[0212] Example 9:
[0213] like Figure 1 and Figure 2 As shown, based on any of the above embodiments, Embodiment 9 provides an insulating frame 100 for a stator assembly 300. The stator assembly 300 includes a winding 310, wires, a stator core 330, and slot insulation 350. The insulating frame 100 includes a mounting member 110, a winding member 130, and a hanging member 140.
[0214] Along the axial direction of the stator assembly 300, the mounting member 110 has a first end and a second end.
[0215] The winding member 130 is provided on the mounting member 110. The winding member 130 is provided with a fixing part 132. At least a portion of the fixing part 132 protrudes from the first end 112 of the mounting member. The fixing part 132 is used to fix the winding 310 and the wire.
[0216] The hanging member 140 is provided on the mounting member 110. The hanging member 140 has a hanging part. The mounting member 110 is located between the axis of the stator assembly 300 and the hanging part, and the hanging part is located at the second end 114 of the mounting member. The hanging part is used to fix the winding 310.
[0217] Furthermore, such as Figure 1As shown, the winding member 130 has a positioning groove 150 on the side facing the hanging part. The positioning groove 150 is used to limit the insulation 350 along the axial limit groove of the stator assembly 300.
[0218] In detail, the winding component 130 has a positioning groove 150 on the side facing the hanging part. The positioning groove 150 serves to limit the slot insulation 350, ensuring the installation position of the slot insulation 350. Specifically, the positioning groove 150 is used to limit the slot insulation 350 along the axial direction of the stator assembly 300. This prevents the slot insulation 350 from damaging the winding 310, and also reduces the thickness of the winding component 130, effectively preventing shrinkage and deformation of the insulation frame 100 during injection molding due to excessive thickness of the winding component 130.
[0219] Example 10:
[0220] like Figure 1 and Figure 2 As shown, based on any of the above embodiments, Embodiment 10 provides an insulating frame 100 for a stator assembly 300. The stator assembly 300 includes a winding 310, wires, a stator core 330, and slot insulation 350. The insulating frame 100 includes a mounting member 110, a winding member 130, and a hanging member 140.
[0221] Along the axial direction of the stator assembly 300, the mounting member 110 has a first end and a second end.
[0222] The winding member 130 is provided on the mounting member 110. The winding member 130 is provided with a fixing part 132. At least a portion of the fixing part 132 protrudes from the first end 112 of the mounting member. The fixing part 132 is used to fix the winding 310 and the wire.
[0223] The hanging member 140 is provided on the mounting member 110. The hanging member 140 has a hanging part. The mounting member 110 is located between the axis of the stator assembly 300 and the hanging part, and the hanging part is located at the second end 114 of the mounting member. The hanging part is used to fix the winding 310.
[0224] Furthermore, such as Figure 1 , Figure 2 , Figure 4 and Figure 7 As shown, the insulating frame 100 also includes a first wire protector 190 and a second wire protector 200.
[0225] The first wire guard 190 and the second wire guard 200 are both connected to the winding member 130. Along the circumference of the stator assembly 300, the winding member 130 is located between the first wire guard 190 and the second wire guard 200.
[0226] The first wire guard 190 and the second wire guard 200 both extend circumferentially along the stator assembly 300.
[0227] In detail, the insulation frame 100 also includes a first wire protector 190 and a second wire protector 200. The winding member 130 is located between the first wire protector 190 and the second wire protector 200 along the circumference of the stator assembly 300. Both the first wire protector 190 and the second wire protector 200 extend circumferentially along the stator assembly 300. The shapes of the first wire protector 190 and the second wire protector 200 are adapted to the shape of the coil of the winding 310. The first wire protector 190 and the second wire protector 200 protect the winding 310, preventing external forces from directly acting on the winding 310 and causing damage to the winding 310.
[0228] Furthermore, such as Figure 1 and Figure 4 As shown, the insulating frame 100 also includes a first connector 210 and a second connector 220.
[0229] The first wire protector 190 and the winding member 130 are connected by the first connector 210.
[0230] The second wire guard 200 and the winding member 130 are connected by the second connector 220.
[0231] Both the first connector 210 and the second connector 220 are arranged in a bent configuration.
[0232] The insulating frame 100 also includes a first connector 210 and a second connector 220. The first wire protector 190 and the winding member 130 are connected by the first connector 210, and the second wire protector 200 and the winding member 130 are connected by the second connector 220.
[0233] Since both the first connector 210 and the second connector 220 are arranged in a bent manner, the structural strength can be enhanced, and the probability of deformation of the insulating frame 100 can be effectively reduced.
[0234] Furthermore, such as Figure 2 , Figure 4 and Figure 6 As shown, the first wire protector 190, the first connector 210 and the winding member 130 are combined to form the first wire protector groove 230; the second wire protector 200, the second connector 220 and the winding member 130 are combined to form the second wire protector groove 240.
[0235] Specifically, by rationally configuring the cooperative structure of the first wire guard 190, the first connector 210, and the winding member 130, the first wire guard 190, the first connector 210, and the winding member 130 are combined to form a first wire guard groove 230. Specifically, the opening and bottom of the first wire guard groove 230 are arranged opposite each other along the axial direction of the stator assembly 300. This configuration reduces material waste, prevents shrinkage and deformation of the insulation frame 100, and provides a safe location for equipment wiring.
[0236] Furthermore, by rationally configuring the cooperation structure of the second wire guard 200, the second connector 220, and the winding member 130, the second wire guard 200, the second connector 220, and the winding member 130 are combined to form a second wire guard groove 240. Specifically, the groove opening and the groove bottom of the second wire guard groove 240 are arranged opposite each other along the axial direction of the stator assembly 300. This configuration reduces material waste, prevents the insulation frame 100 from shrinking and deforming, and provides a safe location for equipment wiring.
[0237] Example 11:
[0238] like Figure 1 As shown, an embodiment of the second aspect of the present invention provides a stator assembly 300, comprising an insulating frame 100 as described in any of the technical solutions in the first aspect.
[0239] In detail, the stator assembly 300, having included the insulating frame 100 as described in any embodiment of the first aspect, has all the beneficial effects of the insulating frame 100 described above, which will not be elaborated here.
[0240] Specifically, the stator assembly 300 includes a stator core 330, an insulating frame 100, slot insulation 350 (slot insulation 350 includes a first slot insulation 352 and a second slot insulation 354) and a winding 310 (winding 310 includes a first winding 311 and a second winding 312).
[0241] The mounting parts 110 of the insulating frame 100 are respectively inserted into the first slot insulation 352 and the second slot insulation 354.
[0242] The stator core 330 has a first inner slot 331 and a second inner slot 336. The first inner slot 331 and the second inner slot 336 are respectively fitted with a first slot insulator 352 and a second slot insulator 354, so that the rotor assembly is insulated from the winding 310.
[0243] The second winding 312 is wound around the second inner slot opening 335 and the fourth inner slot opening 340, respectively.
[0244] The first winding 311 is wound around the first inner slot opening 334 and the third inner slot opening 339 respectively.
[0245] A positioning groove 150 is provided at the bottom of the winding component 130 for positioning and fixing the groove insulation 350.
[0246] Specifically, the slot insulation 350 is insulating paper.
[0247] Example 12:
[0248] An embodiment of the third aspect of the present invention provides an electric motor comprising: an insulating frame 100 as in any embodiment of the first aspect, or a stator assembly 300 as in the second aspect.
[0249] In detail, the motor, having included the insulating frame 100 as in any embodiment of the first aspect or the stator assembly 300 as in the second aspect, has all the beneficial effects of the insulating frame 100 or the stator assembly 300 described above, which will not be described in detail here.
[0250] Example 13:
[0251] The insulating frame 100 includes: a mounting component 110, a winding component 130, a first connector 210, a second connector 220, a hanging component 140, a first wire protector 190, and a second wire protector 200.
[0252] Mounting component 110 has an arc surface 116, two limiting structures 160, a connecting rib 170, and a recess 172.
[0253] Along the circumference of the stator assembly 300, the mounting member 110 has a third end and a fourth end, both of which are provided with a limiting structure 160.
[0254] Two limiting structures 160 are respectively set at the left and right ends of the arc surface 116, and together they act on the stator core 330 to achieve a fastening fit.
[0255] Along the radial direction of the stator assembly 300, the thickness of the mounting member 110 is greater than or equal to 3 mm and less than or equal to 5 mm.
[0256] The central angle k2 corresponding to arc 116 is greater than or equal to 30° and less than or equal to 60°.
[0257] The limiting structure 160 includes a first protrusion 162 and a second protrusion 164, which together form a double-stepped groove structure. The outer surface of the first protrusion 162 includes a first wall and a second wall, both extending axially along the stator assembly 300. The first end of the first wall is connected to the mounting member 110, the second end of the first wall extends in a direction away from the mounting member 110, the third end of the second wall is connected to the second end of the first wall, and the fourth end of the second wall is connected to the mounting member 110. The included angle formed by the first wall and the second wall is greater than or equal to 80° and less than or equal to 100°.
[0258] The outer surface of the second protrusion 164 includes a third wall and a fourth wall, both extending axially along the stator assembly 300. A first end of the third wall is connected to the mounting member 110, and a second end of the third wall extends in a direction away from the mounting member 110. A third end of the fourth wall is connected to the second end of the third wall, and a fourth end of the fourth wall is connected to the mounting member 110. The included angle formed by the third and fourth walls is greater than or equal to 80° and less than or equal to 100°.
[0259] The first protrusion 162 on one side cooperates with the root of the first inner slot 332, and the second protrusion 164 on one side connects to the port of the slot insulation 350 to control the length of the slot insulation 350.
[0260] The first protrusion 162 on the other side cooperates with the root of the second inner slot 333, and the second protrusion 164 on the other side connects with the port of the slot insulation 350 to control the length of the slot insulation 350.
[0261] A third protrusion 166 is added to the middle of the step of the limiting structure 160. The third protrusion 166 can be set at the step angle of the first protrusion 162 or the step angle of the second protrusion 164.
[0262] The cross-sectional shape of the third protrusion 166 includes semi-ellipse, semi-circle, trapezoid, etc., which will not be listed here.
[0263] The height of the third protrusion 166 is greater than or equal to 3mm and less than or equal to 8mm.
[0264] The connecting rib 170 is located on the side of the mounting member 110 opposite to the axis of the stator assembly 300. The number of connecting ribs 170 is greater than or equal to 2 and less than or equal to 8, preferably 4.
[0265] The height of the connecting rib 170 is greater than or equal to 3mm and less than or equal to 10mm, for example, 8mm. It serves to prevent the insulation frame 100 from shrinking and deforming.
[0266] The connecting rib 170 has a recess 172 on the side opposite to the winding member 130. The shape of the recess 172 includes any of the following: semi-circular, semi-elliptical, inverted trapezoidal, semi-rhomboid, etc., which will not be listed here.
[0267] For example, the shape of the recess 172 is semi-circular, which increases the roundness and reduces the possibility of damage to the winding 310.
[0268] The recess 172 is offset from the first wire hanging part 142, the second wire hanging part 144 and the third wire hanging part 146 respectively, and cooperates with the first wire hanging part 140, the second wire hanging part 140 and the third wire hanging part 140 to meet the wire hanging movement trajectory of the wire hanging equipment robot and smoothly and without damage complete the wire transition between stator windings 310.
[0269] Mounting component 110 and winding component 130 are integrally injection molded through connecting rib 170, and the first terminal hole 118, the second terminal hole 120 and the protector terminal hole 122 are constructed simultaneously.
[0270] The winding component 130 has three pairs of latches, namely two first latches 134 and one second latch 136. The latches are distributed in an H-shape.
[0271] The first clip 134 is used to fix and guide the terminals of the winding 310.
[0272] The second latch 136 includes a first latch 134 and a second latch 136, arranged at intervals along the circumference of the stator assembly 300. The end of the first latch 134 facing away from the second latch 136 is a first end face 137, and the end of the second latch 136 facing away from the first latch 134 is a second end face 138. The included angle k1 between the first end face 137 and the second end face 138 is greater than 0° and less than or equal to 10°. The second latch 136 is used for fixing and guiding the wires.
[0273] The winding component 130 has a positioning groove 150 on the side facing the hanging part. The positioning groove 150 is in the shape of a mountain. The positioning groove 150 is used to fix the installation position of the slot insulation 350, to prevent the slot insulation 350 from damaging the winding 310, and at the same time to prevent the winding component 130 from being too thick, which would cause shrinkage and deformation during injection molding.
[0274] The first wire protector 190 and the second wire protector 200 are respectively injection molded on both sides of the winding member 130.
[0275] The first wire guard 190 and the second wire guard 200 extend around the outer periphery of the winding 310 outlet.
[0276] The thickness of both the first protective element 190 and the second protective element 200 meets the requirement of 2mm to 6mm.
[0277] like Figure 7 As shown, the central angle k3 corresponding to the first wire guard 190, the winding member 130, and the second wire guard 200 is greater than or equal to 60° and less than or equal to 150°. For example, k3 includes 70°, 80°, 90°, 100°, 110°, and 120°, etc., which will not be listed here.
[0278] The first wire protector 190, the first connector 210, and the winding member 130 together form the first wire protector groove 230; the second wire protector 200, the second connector 220, and the winding member 130 together form the second wire protector groove 240. This design reduces material waste, prevents the insulation frame 100 from shrinking and deforming, and provides a safe location for the equipment wiring. The shape can be circular, rectangular, elliptical, etc.
[0279] The hanging part 140 is formed behind the bottom end of the mounting part 110, and three inverted arc hooks 148 are respectively provided. The multiple hanging parts include at least a first hanging part 142, a second hanging part 144 and a third hanging part 146. Along the circumference of the stator assembly 300, the first hanging part 142 is located between the second hanging part 144 and the third hanging part 146.
[0280] Along the circumference of the stator assembly 300, the thickness of the first hanging part 142 is three times the thickness of the second hanging part 144, and the thickness of the first hanging part 142 is three times the thickness of the third hanging part 146. The three hanging parts guide and fix the transition winding of the winding 310, preventing the transition winding from popping out and being damaged.
[0281] The first hanging part 142 has a large thickness. The bottom part of the first hanging part 142 is provided with a reinforcing rib 180. The reinforcing rib 180 extends along the first hanging part 142 to the top of the mounting part 110, which increases the hardness of the first hanging part 142 and allows the first hanging part 142 to withstand a certain mechanical force without deformation or damage during the hanging process.
[0282] The first hanging part 142, the second hanging part 144, the third hanging part 146, and the recess 172 of the connecting rib 170 are staggered to ensure that the transition winding 310 smoothly enters the hanging part for fixing.
[0283] Specifically, the shape of the hanging part can be other shapes, such as rectangle, rhombus and semi-ellipse.
[0284] There is one insulating frame 100, which is inserted into one stator slot of the stator core 330. Alternatively, there are two insulating frames 100, one inserted into one stator slot of the stator core 330 and the other inserted into the other stator slot of the stator core 330.
[0285] like Figure 8 As shown, the first winding 311 includes an outer layer 313 and an inner layer 314. The second winding 312 includes an outer layer 315 and an inner layer 316. The outer layer 313 of the first winding is outside the inner layer 314 of the first winding, and similarly, the outer layer 315 of the second winding is outside the inner layer 316 of the second winding.
[0286] like Figure 5 As shown, the length of hook 148 is denoted as L, and the height of hook 148 is denoted as H. H satisfies: 2.5mm to 5.5mm, more specifically, H satisfies: 2.5mm to 3.5mm. L satisfies: 5mm to 10mm, more specifically, L satisfies: 5mm to 8.5mm.
[0287] Example 14:
[0288] like Figure 9 and Figure 10 As shown, point C is the starting point of winding 310, located on the surface of the first inner slot opening 334. The wire enters in a direction perpendicular to the inner slot of the stator, exits from the bottom surface of the first inner slot opening 334, and then falls to the bottom of the third inner slot opening 339 to the lower left. After winding in a direction perpendicular to the inner slot of the stator, the wire exits from the surface of the third inner slot opening 339, and then enters again on the surface of the first inner slot opening 334 to form a cycle. After the winding 310 is wound in a cycle to the required number of turns Q1, the outer layer 313 of the first winding is formed.
[0289] At this time, the wire of winding 310 returns to the surface of the first inner slot opening 334. The winding 310 returns to the surface of the second inner slot opening 335 in the order of the first buckle 134, the second buckle 136 and the first buckle 134 of the winding member 130. Using the same method, the winding 310 is circulated between the surface of the second inner slot opening 335, the bottom surface of the second inner slot opening 335, the bottom surface of the fourth inner slot opening 340 and the surface of the fourth inner slot opening 340. After the winding 310 wire circulates a specific number of turns Q1, it is pulled out at the surface of the second inner slot opening 335 to form the outer layer 315 of the second winding and the tap end D.
[0290] The wire of winding 310 continues to deflect towards the stator inner slot along the outer layer 315 direction of the second winding, and continues to cycle in the manner of the outer layer 315 of the second winding. After winding Q2 turns, it returns to the surface of the second inner slot opening 335 to form the inner layer 316 of the second winding. The wire of winding 310 returns to the surface of the first inner slot opening 334 along the sequence of the first latch 134, the second latch 136, and the first latch 134 of the winding member 130. It continues to deflect towards the stator inner slot along the outer layer 313 direction of the first winding, and continues to cycle in the manner of the outer layer 313 of the first winding. After winding Q2 turns, it returns to the surface of the first inner slot opening 334 to form the inner layer 314 of the first winding. The wire of winding 310 is pulled out from the surface of the first inner slot opening 334 to form the end point E of winding 310.
[0291] The winding component 130 buckle is used instead of the hanging component 140 inverted hook 148 structure, which simplifies the structure, but requires higher process requirements for the winding equipment.
[0292] Example 15:
[0293] like Figure 11 and Figure 12As shown, point C is the starting point of the winding 310, located on the surface of the first inner slot opening 334. The wire enters perpendicular to the direction of the stator inner slot opening, exits from the bottom surface of the first inner slot opening 334, and then falls towards the bottom of the third inner slot opening 339. After winding perpendicular to the direction of the stator inner slot opening, the wire exits from the surface of the third inner slot opening 339, and then re-enters the wire on the surface of the first inner slot opening 334 to form a cycle. After the winding 310 is wound to the required number of turns Q1, the outer layer 313 of the first winding is formed. The wire is then wound from the bottom surface of the third inner slot opening 339 of the stator along the direction of the hanging member 140 of the first insulating frame 100. The wire of the winding 310 is sequentially fastened in the first clip 134, the second clip 136, and the first clip 134 to guide the wire of the winding 310 and store the wire of the winding 310 to prevent damage. After passing through the hanging member 140, the wire of winding 310 reaches the bottom surface of the fourth inner slot opening 340. It passes out towards the stator inner slot hole, and in the same way, the winding 310 is circulated between the bottom surface of the fourth inner slot opening 340, the surface of the fourth inner slot opening 340, the surface of the second inner slot opening 335, and the bottom surface of the second inner slot opening 335. After circulating a specific number of turns Q1, the wire of winding 310 is pulled out at the surface of the fourth inner slot opening 340 to form the outer layer 315 of the second winding and the tap end D.
[0294] The wire of winding 310 continues to deflect towards the stator inner slot along the outer layer 315 of the second winding, and continues to cycle in the manner of the outer layer 315 of the second winding. After winding 2 turns, it returns to the bottom surface of the second inner slot opening 335 to form the inner layer 316 of the second winding. Along the hanging member 140 of the second insulating frame 100, the wire of winding 310 is sequentially fastened in the first clip 134, the second clip 136 and the first clip 134. After passing through the hanging member 140, the wire of winding 310 reaches the bottom surface of the first inner slot opening 334, and continues to deflect towards the stator inner slot along the outer layer 313 of the first winding. After winding 2 turns, it returns to the surface of the first inner slot opening 334 to form the inner layer 314 of the first winding. The wire of winding 310 is pulled out from the surface of the first inner slot opening 334 to form the end point E of winding 310.
[0295] The motor consists of two insulating frames 100. The manufacturing process is simple, but it requires a lot of materials.
[0296] Example 16:
[0297] like Figure 13 and Figure 14As shown, point C is the starting point of the winding 310, located on the surface of the first inner slot opening 334. The wire enters in a direction perpendicular to the stator inner slot opening, exits from the bottom surface of the first inner slot opening 334, and then falls towards the bottom of the third inner slot opening 339. After winding in a direction perpendicular to the stator inner slot opening, the wire exits on the surface of the third inner slot opening 339, and then re-enters on the surface of the first inner slot opening 334 to form a cycle. After the winding 310 is wound to the required number of turns Q1, the outer layer 313 of the first winding is formed. The wire is wound from the bottom surface of the first inner slot opening 334 along the direction of the hanging member 140 of the insulation frame 100. The wire of the winding 310 is sequentially fastened in the first clip 134, the second clip 136, and the first clip 134 to guide the wire of the winding 310 and store the wire of the winding 310 to prevent damage. After the wire of winding 310 passes through the hanging member 140, it reaches the bottom surface of the second inner slot opening 335 and exits in the direction of the stator inner slot. Using the same method, the wire of winding 310 is made to circulate between the bottom surface of the fourth inner slot opening 340, the surface of the fourth inner slot opening 340, the surface of the second inner slot opening 335, and the bottom surface of the second inner slot opening 335. After the wire of winding 310 circulates a specific number of turns Q1, it is pulled out at the surface of the second inner slot opening 335 to form the outer layer 315 of the second winding and the tap end D.
[0298] The wire of winding 310 continues to deflect towards the stator inner slot along the outer layer 315 of the second winding, and continues to cycle in the manner of the outer layer 315 of the second winding. After winding Q2 turns, it returns to the bottom surface of the second inner slot opening 335 to form the inner layer 316 of the second winding. Along the hanging member 140 of the second insulating frame 100, the wire of winding 310 is sequentially fastened in the first clip 134, the second clip 136 and the first clip 134. After passing through the hanging member 140, the wire of winding 310 reaches the bottom surface of the first inner slot opening 334. It continues to deflect towards the stator inner slot along the outer layer 313 of the first winding, and continues to cycle in the manner of the outer layer 313 of the first winding. After winding Q2 turns, it returns to the surface of the first inner slot opening 334 to form the inner layer 314 of the first winding. The wire of winding 310 is pulled out from the surface of the first inner slot opening 334 to form the end point E of winding 310.
[0299] This setup can reduce the number of terminals, reduce the amount of wire used in winding 310, reduce the amount of material used in insulation frame 100, simplify the production process, improve production efficiency, and optimize motor performance.
