Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a stator assembly and a motor. Background Art

[0002] At present, in the related art, a stator core is provided in the stator assembly, and a winding is provided on the stator core. An insulating frame is provided at the end of the stator core to protect the end of the stator core, and then the winding at the end of the stator core is protected. However, the insulating frame is usually assembled on the stator core using an injection molding process, or is installed on the stator core using a separate mounting part. However, the injection molding process and the way of installing the insulating frame with a separate mounting part make the assembly process of the stator assembly complicated. Utility Model Content

[0003] The utility model aims to solve at least one of the technical problems existing in the prior art or related technologies.

[0004] To this end, a first aspect of the present invention provides a stator assembly.

[0005] A second aspect of the present invention provides a motor.

[0006] In view of this, the first aspect of the present invention provides a stator assembly comprising a stator core, a first frame, windings, and slot paper. The stator core has stator slots; the first frame is disposed on the stator core and located on a first axial side of the stator core; the windings are embedded in the stator slots; the slot paper comprises a first body and a first positioning portion. The first body is disposed in the stator slots and located between the windings and the stator core. The first positioning portion is connected to the first body and abuts a side of the first frame away from the stator core.

[0007] In this technical solution, the stator assembly includes a stator core, a first skeleton, windings and slot paper. The stator core has stator slots to realize the arrangement of the stator slots. The first skeleton is arranged in the stator core, and is located on the first side of the stator core in the axial direction to realize the installation of the first skeleton. The winding is embedded in the stator slot to realize the installation of the winding and prevent the winding from moving when the motor is running. The slot paper includes a first body and a first positioning portion. The first body is arranged in the stator slot, and is located between the winding and the stator core to realize the installation of the first body, so that the first body can isolate the stator core and the winding to prevent the stator core and the winding from direct contact and short circuit. In addition, the first body can also protect the winding. The first positioning portion is connected to the first body and abuts against the side of the first skeleton away from the stator core to realize the installation of the first positioning portion. Since the first skeleton is arranged on one side of the stator core in the axial direction, the first positioning portion abuts against the side of the first skeleton away from the stator core, so that the first positioning portion can limit the first skeleton, thereby preventing the first skeleton from moving relative to the stator core, so as to achieve the fixation of the first skeleton, so that the first skeleton can protect the first side of the stator core in the axial direction and prevent the winding on the first side of the stator core in the axial direction from being deformed. The present application uses slot paper to fix the first skeleton, which can improve the stability of the first skeleton after installation, and there is no need to use a separate installation component to install the first skeleton. Compared with using a separate component to install the first skeleton and using injection molding of the first skeleton, the installation structure of the first skeleton is simplified and the difficulty of installing the first skeleton is reduced. In addition, the first skeleton is fixed by the slot paper, so that the first skeleton does not affect the assembly of the slot paper.

[0008] In addition, the stator assembly in the above technical solution provided by the present invention may also have the following additional technical features:

[0009] In some technical solutions of the present invention, optionally, the first skeleton includes a second body and a support component. The second body is attached to the end surface of the stator core on the first side in the axial direction. The support component is provided on the second body, and the terminal of the winding is connected to the support component.

[0010] In this technical solution, the first skeleton includes a second body and a supporting component. The second body is fitted to the end face of the first side of the stator core in the axial direction to achieve the installation of the second body, so that the second body can fix the end of the winding, and can also protect the first side of the stator core in the axial direction to prevent the winding from deforming during the movement of the stator core, thereby ensuring the stability of the winding. In addition, the second body can also prevent external impurities from entering the interior of the winding, thereby extending the service life of the winding. The supporting component is provided on the second body to achieve the installation and fixation of the supporting component. The terminal of the winding is connected to the supporting component, so that the terminal of the winding can be fixed, which facilitates the wiring operation of the terminal of the winding and ensures that the terminal is more secure after installation. Therefore, by providing the second body and the supporting component, the probability of the end of the winding breaking can be reduced.

[0011] In some technical solutions of the present invention, optionally, in the axial direction of the stator core, the first side of the first body protrudes from the second body, the first positioning portion is located on the outside of the first body, the first side of the first positioning portion is connected to the first side of the first body, and the second side of the first positioning portion is against the second body.

[0012] In this technical solution, in the axial direction of the stator core, the first side of the first body protrudes from the second body, and the first positioning portion is located on the outside of the first body to achieve the installation of the first body and the second positioning portion. The first side of the first positioning portion is connected to the first side of the first body, so that the first positioning portion and the first body can be fixed together. The second side of the first positioning portion abuts against the second body, so that the second body can be clamped between the second side of the first positioning portion and the stator core. The second side of the first positioning portion can limit the movement of the second body, thereby achieving the fixation of the first skeleton and then firmly positioning the first skeleton on the end face of the stator core through the first positioning portion. The first skeleton is installed on the stator core of the motor without increasing the process and workload, thereby reducing the difficulty of installing the first skeleton.

[0013] In some technical solutions of the present invention, optionally, the stator assembly further includes a power line, which is arranged on the supporting component and connected to the terminal of the winding.

[0014] In this technical solution, the stator assembly also includes a power cord, which is mounted on a support member and connected to the winding terminals. This allows the power cord to be arranged so that the windings can receive power from the power cord to facilitate motor operation. Since the winding terminals are mounted on the support member, securing the winding terminals to the power cord prevents the windings from directly dragging the power cord, thus avoiding quality risks caused by disconnection during transport of the stator assembly.

[0015] In some technical solutions of the present invention, the support component optionally includes a first support column and a second support column. The first support column is provided on the second body, located on a side of the second body away from the stator core, and extends in an axial direction away from the stator core, with the terminal of the winding wound around the first support column; the second support column is provided on the second body, located on a side of the second body away from the stator core, and extends in an axial direction away from the stator core, with the power cord wound around the second support column and connected to the terminal of the winding.

[0016] In this technical solution, the support component includes a first support column and a second support column. The first support column is arranged on the second body, located on the side of the second body away from the stator core, and extends in the axial direction of the stator core in the direction away from the stator core to realize the arrangement of the first support column. The terminal of the winding is wound around the first support column, so that the first support column can fix the terminal of the winding. The second support column is arranged on the second body, located on the side of the second body away from the stator core, and extends in the axial direction of the stator core in the direction away from the stator core to realize the arrangement of the second support column. The power cord is wound around the second support column and connected to the terminal of the winding, so that the second support column can fix the power cord, so that the terminal of the power cord and the winding are fixed separately, avoiding the winding directly dragging the power cord.

[0017] In some technical solutions of the present invention, optionally, the power line and the connection terminal of the winding are riveted through piercing terminals.

[0018] In this technical solution, the power cord and winding terminals are riveted together using piercing terminals to achieve electrical connection between the power cord and winding, thereby enabling the transfer of electrical energy. By adopting the piercing terminal riveting process, the winding eliminates the need for welding processability issues and allows the use of aluminum enameled wire, which has better winding processability, thus improving the quality and production efficiency of the motor.

[0019] In some technical solutions of the present invention, optionally, the first skeleton further includes a mounting foot, which is connected to the second body and extends along the axial direction of the stator core and abuts against the circumferential side wall of the stator core.

[0020] In this technical solution, the first frame also includes mounting feet, which are connected to the second body and extend axially along the stator core, resting against the circumferential side walls of the stator core to facilitate the placement of the mounting feet. By providing the mounting feet, the first frame can be pre-fixed to the stator core by having the mounting feet rest against the circumferential side walls of the stator core during stator assembly, i.e., when the slot paper is not installed on the stator core. After the first frame is pre-installed using the mounting feet, the first frame is securely positioned on the end face of the stator core using the first positioning portion of the slot paper. The first frame can then be installed on the motor stator core without increasing the number of steps or workload, making installation of the first frame more convenient and improving installation efficiency.

[0021] In some technical solutions of the present invention, optionally, there are multiple mounting feet, and the multiple mounting feet are arranged along the circumference of the stator core.

[0022] In this technical solution, multiple mounting legs are provided, and the multiple mounting legs are arranged along the circumference of the stator core to achieve a multi-mount arrangement. The provision of multiple mounting legs ensures precise positioning of the first frame on the stator core and provides a more stable support, preventing the first frame from falling off after installation.

[0023] In some technical solutions of the present invention, optionally, the second body is provided with a groove, and along the axial direction of the stator core, the groove is opposite to the stator slot.

[0024] In this technical solution, the second body is provided with grooves that, along the axial direction of the stator core, oppose the stator slots to achieve the desired groove arrangement. This arrangement of the second body allows for smooth installation of the slot paper, preventing the first frame from interfering with the entry of the slot paper into the stator slots, thereby improving stator assembly efficiency.

[0025] In some technical solutions of the present invention, optionally, there are multiple stator slots, the multiple stator slots are arranged along the circumferential direction of the stator core, and a first tooth portion is provided between two adjacent stator slots among the multiple stator slots; there are multiple grooves, the multiple grooves are arranged along the circumferential direction of the stator core, and a second tooth portion is provided between two adjacent grooves among the multiple grooves; wherein, the width of the first tooth portion in the circumferential direction of the stator core is a first width, the width of the second tooth portion in the circumferential direction of the stator core is a second width, and the first width is greater than or equal to the second width.

[0026] In this technical solution, there are multiple stator slots, and the multiple stator slots are arranged along the circumference of the stator core to achieve the arrangement of the multiple stator slots. A first tooth portion is provided between two adjacent stator slots in the multiple stator slots to achieve the arrangement of the first tooth portion. There are multiple grooves, and the multiple grooves are arranged along the circumference of the stator core to achieve the arrangement of the multiple grooves. A second tooth portion is provided between two adjacent grooves in the multiple grooves to achieve the arrangement of the second tooth portion. The width of the first tooth portion in the circumferential direction of the stator core is a first width, and the width of the second tooth portion in the circumferential direction of the stator core is a second width, and the first width is greater than or equal to the second width, so as to achieve the adjustment of the widths of the first tooth portion and the second tooth portion. By making the first width greater than or equal to the second width, the size of the stator slot is made smaller than or equal to the size of the groove, so that the slot paper passes through the first skeleton and enters the stator slot, further reducing the influence of the first skeleton on the slot paper entering the stator slot.

[0027] In some technical solutions of the present invention, optionally, the first skeleton also includes a protective part, a first side of the protective part is connected to the second body, and the second side of the protective part extends along the axial direction of the stator core away from the stator core. The protective part is arranged along the circumference of the stator core and is located on the outside of the winding.

[0028] In this technical solution, the first frame also includes a protective portion. A first side of the protective portion is connected to the second body, and a second side of the protective portion extends axially away from the stator core. The protective portion is arranged circumferentially around the stator core and outside the windings, thereby achieving a protective arrangement. The annular protective portion protects the ends of the stator core where the windings are located. This ensures that, in the event of a collision during transport of the stator assembly, the protective portion is impacted first, thereby preventing damage to the protective portion and minimizing damage to the windings.

[0029] In some technical solutions of the present invention, optionally, the stator assembly also includes a second frame, which is arranged on the side of the stator core away from the first frame; the slot paper also includes a second positioning portion, which is connected to the side of the first body away from the first positioning portion and abuts against the second frame.

[0030] In this technical solution, the stator assembly also includes a second skeleton, which is arranged on the side of the stator core away from the first skeleton to realize the arrangement of the second skeleton, so that the second skeleton can protect the side of the stator core away from the first skeleton. The slot paper also includes a second positioning portion, which is connected to the side of the first body away from the first positioning portion and abuts against the second skeleton to realize the installation of the second positioning portion, so that the second positioning portion can limit the second skeleton, thereby preventing the second skeleton from moving relative to the stator core, so as to realize the fixation of the second skeleton, so that the second skeleton can protect the side of the stator core away from the first skeleton and prevent the winding from being deformed. By limiting the second skeleton with the second positioning portion, the installation structure of the second skeleton is simplified and the difficulty of installing the second skeleton is reduced. In addition, the second skeleton is fixed by the slot paper so that the second skeleton will not affect the assembly of the slot paper.

[0031] In some technical solutions of the present invention, optionally, the first skeleton is an insulating skeleton.

[0032] In this technical solution, the first frame is an insulating frame, which can effectively protect the ends of the windings, reduce damage to the stator assembly during transportation, and improve the insulation effect between the windings and the stator core.

DETAILED DESCRIPTION

[0048] In order to more clearly understand the above-mentioned objectives, features and advantages of the present invention, the present invention is further described in detail below in conjunction with the accompanying drawings and specific embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0049] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0050] Refer to the following Figures 1 to 10 A stator assembly 100 and an electric machine according to some embodiments of the present invention are described.

[0051] like Figure 1 、 Figure 2 and Figure 3 As shown, the present application provides a stator assembly 100, including a stator core 102, a first frame 108, a winding 124 and a slot paper 126. The stator core 102 has stator slots 104; the first frame 108 is provided on the stator core 102, and is located on a first side of the stator core 102 in the axial direction; the winding 124 is embedded in the stator slot 104; Figure 3 and Figure 4 As shown, the slot paper 126 includes a first body 128 and a first positioning portion 130. The first body 128 is disposed in the stator slot 104 and is located between the winding 124 and the stator core 102. The first positioning portion 130 is connected to the first body 128 and abuts against the side of the first frame 108 away from the stator core 102.

[0052] In this embodiment, the stator assembly 100 includes a stator core 102, a first frame 108, windings 124, and slot paper 126. The stator core 102 has stator slots 104 to facilitate the arrangement of the stator slots 104. The first frame 108 is disposed on the stator core 102, located on a first axial side of the stator core 102, to facilitate the installation of the first frame 108. The windings 124 are embedded in the stator slots 104 to facilitate the installation of the windings 124 and prevent them from moving during motor operation. The slot paper 126 includes a first body 128 and a first positioning portion 130. The first body 128 is disposed within the stator slots 104, between the windings 124 and the stator core 102, to facilitate installation of the first body 128. The first body 128 isolates the stator core 102 from the windings 124, preventing direct contact between the stator core 102 and the windings 124 and a short circuit. Furthermore, the first body 128 protects the windings 124. A first positioning portion 130 is connected to the first body 128 and abuts against the side of the first frame 108 away from the stator core 102 to facilitate installation of the first positioning portion 130. Since the first frame 108 is arranged on one side of the stator core 102 in the axial direction, the first positioning portion 130 abuts against the side of the first frame 108 away from the stator core 102, so that the first positioning portion 130 can limit the first frame 108, thereby preventing the first frame 108 from moving relative to the stator core 102, so as to achieve the fixation of the first frame 108, so that the first frame 108 can protect the first side of the stator core 102 in the axial direction and prevent the winding 124 on the first side of the stator core 102 from deforming in the axial direction. The present application uses slot paper 126 to fix the first frame 108, which can improve the stability of the first frame 108 after installation, and does not require the use of a separate installation component to install the first frame 108. Compared with the method of installing the first frame 108 with a separate component and the method of injection molding the first frame 108, the installation structure of the first frame 108 is simplified and the installation difficulty of the first frame 108 is reduced. Furthermore, the first frame 108 is fixed by the slot paper 126 so that the first frame 108 does not affect the assembly of the slot paper 126 .

[0053] Specifically, in Figure 1 The middle arrow B indicates the axial direction of the stator core 102 .

[0054] Specifically, the winding 124 is an enameled wire winding.

[0055] This embodiment provides a stator assembly 100 . In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0056] like Figure 5As shown, the first frame 108 includes a second body 110 and a support member 116. The second body 110 is attached to the end surface of the first side of the stator core 102 in the axial direction; the support member 116 is provided on the second body 110, and the terminal 142 of the winding 124 is connected to the support member 116.

[0057] In this embodiment, the first skeleton 108 includes a second body 110 and a support component 116. The second body 110 is attached to the end surface of the first side of the stator core 102 in the axial direction to achieve the installation of the second body 110, so that the second body 110 can fix the end of the winding 124. It can also protect the first side of the stator core 102 in the axial direction to prevent the winding 124 from deforming during the movement of the stator core 102, thereby ensuring the stability of the winding 124. In addition, the second body 110 can also prevent external impurities from entering the interior of the winding 124, thereby extending the service life of the winding 124. The support component 116 is provided on the second body 110 to achieve the installation and fixation of the support component 116. The terminal 142 of the winding 124 is connected to the support component 116, so that the terminal 142 of the winding 124 can be fixed, which facilitates the wiring operation of the terminal 142 of the winding 124 and ensures that the terminal 142 is more secure after installation. Therefore, by setting the second body 110 and the support component 116, the probability of the end of the winding 124 breaking can be reduced.

[0058] This embodiment provides a stator assembly 100 . In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0059] like Figure 4 As shown, in the axial direction of the stator core 102, the first side of the first body 128 protrudes from the second body 110, the first positioning portion 130 is located on the outside of the first body 128, the first side of the first positioning portion 130 is connected to the first side of the first body 128, and the second side of the first positioning portion 130 is against the second body 110.

[0060] In this embodiment, the first side of the first body 128 protrudes from the second body 110 in the axial direction of the stator core 102, and the first positioning portion 130 is located outside the first body 128 to facilitate installation of the first body 128 and the second positioning portion 140. The first side of the first positioning portion 130 is connected to the first side of the first body 128, allowing the first positioning portion 130 and the first body 128 to be fixed together. The second side of the first positioning portion 130 abuts against the second body 110, allowing the second body 110 to be sandwiched between the second side of the first positioning portion 130 and the stator core 102. The second side of the first positioning portion 130 limits the movement of the second body 110, thereby securing the first frame 108. The first positioning portion 130 securely positions the first frame 108 on the end surface of the stator core 102. This allows the first frame 108 to be installed on the motor stator core 102 without increasing the number of steps or workload, thus reducing the difficulty of installing the first frame 108.

[0061] This embodiment provides a stator assembly 100 . In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0062] like Figure 5 As shown, the stator assembly 100 further includes a power line 132 , which is disposed on the support member 116 and connected to the terminal 142 of the winding 124 .

[0063] In this embodiment, the stator assembly 100 further includes a power cord 132, which is disposed on the support member 116 and connected to the terminal 142 of the winding 124. This allows the power cord 132 to be arranged so that the winding 124 can receive power provided by the power cord 132 to facilitate motor operation. Since the terminal 142 of the winding 124 is disposed on the support member 116, the terminal 142 of the winding 124 and the power cord 132 are fixed together. This prevents the winding 124 from directly dragging the power cord 132, thereby avoiding quality risks caused by disconnection during the transportation of the stator assembly 100.

[0064] Specifically, the first skeleton 108 of the present application can effectively prevent the wire breakage quality problem caused by the winding 124 directly dragging the power line 132.

[0065] This embodiment provides a stator assembly 100 . In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0066] like Figure 5 and Figure 6As shown, the support component 116 includes a first support column 118 and a second support column 120. The first support column 118 is disposed on the second body 110, located on a side of the second body 110 away from the stator core 102, and extends in an axial direction away from the stator core 102. The terminal 142 of the winding 124 is wound around the first support column 118. The second support column 120 is disposed on the second body 110, located on a side of the second body 110 away from the stator core 102, and extends in an axial direction away from the stator core 102. The power line 132 is wound around the second support column 120 and connected to the terminal 142 of the winding 124.

[0067] In this embodiment, the support component 116 includes a first support column 118 and a second support column 120. The first support column 118 is disposed on the second body 110, located on a side of the second body 110 away from the stator core 102, and extends in the axial direction of the stator core 102 in a direction away from the stator core 102 to facilitate the arrangement of the first support column 118. The terminal 142 of the winding 124 is wound around the first support column 118, so that the first support column 118 can fix the terminal 142 of the winding 124. The second support column 120 is disposed on the second body 110, located on a side of the second body 110 away from the stator core 102, and extends in the axial direction of the stator core 102 in a direction away from the stator core 102 to facilitate the arrangement of the second support column 120. The power cord 132 is wound around the second support column 120 and connected to the terminal 142 of the winding 124, so that the second support column 120 can fix the power cord 132, thereby fixing the power cord 132 and the terminal 142 of the winding 124 separately, avoiding the winding 124 directly dragging the power cord 132.

[0068] Specifically, the support component 116 includes a first support column 118 and one of the second support columns 120, that is, the number of support columns is one, and the power cord 132 and the terminal 142 of the winding 124 are both wound around the support column, and one of the first support column 118 and the second support column 120 simultaneously fixes the power cord 132 and the terminal 142 of the winding 124.

[0069] Specifically, when the support component 116 includes one of the first support column 118 and the second support column 120, the support column can be a conductive component, and the power line 132 and the terminal 142 of the winding 124 are wound around the support column and are also electrically connected through the support column.

[0070] This embodiment provides a stator assembly 100 . In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0071] like Figure 5As shown, the power wire 132 is riveted to the terminal 142 of the winding 124 via the piercing terminal 134 .

[0072] In this embodiment, the power cord 132 is riveted to the terminal 142 of the winding 124 via the piercing terminal 134, thereby achieving electrical connection between the power cord 132 and the winding 124 and thus enabling power transfer. By employing the piercing terminal 134 riveting process, the winding 124 eliminates the need for welding processability issues and can utilize aluminum enameled wire, which has better winding processability, thereby improving motor quality and production efficiency.

[0073] Specifically, align the power cord 132 with the terminal of the winding 124, connect one end of the piercing terminal 134 to the power cord 132, connect the other end of the piercing terminal 134 to the terminal of the winding 124, apply pressure to the piercing terminal 134, so that the piercing terminal 134 is deformed and tightly wrapped around the power cord 132 and the terminal of the winding 124, thereby achieving riveting the power cord 132 and the terminal of the winding 124 together through the piercing terminal 134.

[0074] Specifically, the piercing terminal 134 is disposed on the second body 110 , and the second body 110 can fix the piercing terminal 134 to prevent the piercing terminal 134 from moving.

[0075] Specifically, the piercing terminal 134 may be movable relative to the second body 110 .

[0076] Specifically, the support member 116 provides a support for the winding terminal 142 of the winding 124 to be wound around, thereby providing a process foundation for implementing the riveting process of the power cord 132 and the winding terminal 142 by piercing the terminal 134. Through this riveting process, the winding 124 does not need to consider welding processability issues, and aluminum enameled wire with better winding processability can be used, thereby improving the quality and production efficiency of the motor.

[0077] Specifically, the first positioning portion 130 is the flanged end of the slot paper 126. During the production period when the slot paper 126 is installed, the first frame 108 is placed on the stator core 102 and secured by the flanged end of the slot paper 126. The terminal 142 of the winding 124 is wrapped around the protruding support member 116 of the first frame 108, and then the winding 124 is connected to the power cord 132 using terminal riveting. Because both the winding 124 and the power cord 132 are riveted to the first frame 108, this method prevents the winding 124 from directly dragging the power cord 132, thereby avoiding quality risks caused by wire breakage during transportation of the stator assembly 100. At the same time, because the first skeleton 108 is set at the end of the stator core 102, the insulation material occupancy rate of the stator slot 104 area is reduced, and the slot fill rate of the winding 124 is reduced, which is beneficial to the production of the stator assembly 100. At the same time, the first skeleton 108 can effectively reduce the cost of the insulation skeleton and has strong production applicability.

[0078] Specifically, the wall thickness of the first frame 108 is greater than or equal to 0.5 mm, the thickness of the insulating polyester film is 0.188 mm, and the wall thickness of the first frame 108 is greater than the thickness of the polyester film.

[0079] Specifically, the wall thickness of the first skeleton 108 is 0.5 mm.

[0080] Specifically, the wall thickness of the first skeleton 108 is 0.7 mm.

[0081] Specifically, the wall thickness of the first skeleton 108 is 0.9 mm.

[0082] This embodiment provides a stator assembly 100 . In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0083] like Figure 1 、 Figure 2 and Figure 7 As shown, optionally, the first skeleton 108 further includes a mounting foot 122 , which is connected to the second body 110 and extends along the axial direction of the stator core 102 and abuts against the circumferential side wall of the stator core 102 .

[0084] In this embodiment, the first frame 108 further includes mounting feet 122, which are connected to the second body 110 and extend axially along the stator core 102, abutting against the circumferential sidewalls of the stator core 102 to facilitate the placement of the mounting feet 122. By providing the mounting feet 122, the first frame 108 can be pre-fixed to the stator core 102 during assembly of the stator assembly 100, i.e., when the slot paper 126 is not installed on the stator core 102, by abutting the circumferential sidewalls of the stator core 102. After the first frame 108 is pre-installed with the mounting feet 122, the first positioning portion 130 of the slot paper 126 securely positions the first frame 108 on the end face of the stator core 102. This allows the first frame 108 to be installed on the motor stator core 102 without increasing the number of steps or workload, making installation of the first frame 108 more convenient and improving installation efficiency.

[0085] Specifically, in Figure 2 The middle arrow A indicates the circumferential direction of the stator core 102 .

[0086] This embodiment provides a stator assembly 100 . In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0087] like Figure 7 As shown, there are multiple mounting legs 122 , and the multiple mounting legs 122 are arranged along the circumference of the stator core 102 .

[0088] In this embodiment, there are multiple mounting legs 122, which are arranged along the circumference of the stator core 102 to achieve the arrangement of multiple mounting legs 122. By providing multiple mounting legs 122, the first frame 108 can be accurately positioned on the stator core 102, and a more stable support can be formed to prevent the first frame 108 from falling off after installation.

[0089] Specifically, there are two mounting feet 122 , and the two mounting feet 122 are arranged along the circumference of the stator core 102 .

[0090] Specifically, there are four mounting legs 122 , and the four mounting legs 122 are arranged along the circumference of the stator core 102 .

[0091] Specifically, the first skeleton 108 is positioned on the end face of the stator core 102 by four mounting feet 122. Before the stator core 102 is inserted into the slot paper 126 during the production process, the first skeleton 108 is installed on the stator core 102 that has not been inserted into the slot paper 126 by the mounting feet 122, and then the first skeleton 108 is firmly positioned on the end face of the stator core 102 by the first positioning portion 130. The first skeleton 108 is installed on the stator core 102 without increasing the process and workload. According to needs, the first skeleton 108 can be added to only one end face of the stator core 102. After the winding 124 is embedded in the stator core 102, the terminal 142 of the graded winding 124 is wrapped around the support component 116, and then the power cord 132 is riveted to the terminal 142 of the corresponding gear winding 124 through a riveting process, and the terminal 142 of the winding 124 and the power cord 132 are fixed to the support component 116.

[0092] This embodiment provides a stator assembly 100 . In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0093] like Figure 7 As shown, the second body 110 is provided with a groove 112 , and along the axial direction of the stator core 102 , the groove 112 is opposite to the stator slot 104 .

[0094] In this embodiment, the second body 110 is provided with grooves 112. Along the axial direction of the stator core 102, the grooves 112 are opposite the stator slots 104, thereby achieving the arrangement of the grooves 112. Providing the grooves 112 on the second body 110 allows for smooth installation of the slot paper 126, preventing the first frame 108 from interfering with the entry of the slot paper 126 into the stator slots 104, thereby improving the assembly efficiency of the stator assembly 100.

[0095] Specifically, the groove 112 is opposite to the stator slot 104 , so that the shape of the end of the first skeleton 108 is adapted to the shape of the stator core 102 .

[0096] This embodiment provides a stator assembly 100 . In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0097] like Figure 2 As shown, there are multiple stator slots 104, and the multiple stator slots 104 are arranged along the circumference of the stator core 102. There is a first tooth portion 106 between two adjacent stator slots 104 in the multiple stator slots 104; Figure 7 As shown, there are multiple grooves 112, and the multiple grooves 112 are arranged along the circumference of the stator core 102. There is a second tooth portion 114 between two adjacent grooves 112 in the multiple grooves 112; Figure 2As shown, the width of the first tooth portion 106 in the circumferential direction of the stator core 102 is a first width. Figure 7 As shown, the width of the second tooth portion 114 in the circumferential direction of the stator core 102 is a second width, and the first width is greater than or equal to the second width.

[0098] In this embodiment, there are multiple stator slots 104, which are arranged along the circumference of the stator core 102 to achieve the arrangement of the multiple stator slots 104. A first tooth portion 106 is provided between two adjacent stator slots 104 in the multiple stator slots 104 to achieve the arrangement of the first tooth portion 106. There are multiple grooves 112, which are arranged along the circumference of the stator core 102 to achieve the arrangement of the multiple grooves 112. A second tooth portion 114 is provided between two adjacent grooves 112 in the multiple grooves 112 to achieve the arrangement of the second tooth portion 114. The first tooth portion 106 has a first width in the circumferential direction of the stator core 102, and the second tooth portion 114 has a second width in the circumferential direction of the stator core 102. The first width is greater than or equal to the second width, so that the widths of the first tooth portion 106 and the second tooth portion 114 can be adjusted. By making the first width greater than or equal to the second width, the size of the stator slot 104 is made smaller than or equal to the size of the groove 112 , thereby allowing the slot paper 126 to pass through the first frame 108 and enter the stator slot 104 , further reducing the influence of the first frame 108 on the slot paper 126 entering the stator slot 104 .

[0099] Specifically, in Figure 2 In the figure, C represents the first width.

[0100] Specifically, in Figure 7 In FIG, D represents the second width.

[0101] Specifically, the number of stator slots 104 is 16, and the number of grooves 112 is 16.

[0102] Specifically, the number of stator slots 104 is the same as the number of grooves 112 .

[0103] This embodiment provides a stator assembly 100 . In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0104] like Figure 1 As shown, the first skeleton 108 also includes a protective portion 136, a first side of the protective portion 136 is connected to the second body 110, and a second side of the protective portion 136 extends along the axial direction of the stator core 102 away from the stator core 102. The protective portion 136 is arranged along the circumference of the stator core 102 and is located on the outside of the winding 124.

[0105] In this embodiment, the first frame 108 further includes a protective portion 136. A first side of the protective portion 136 is connected to the second body 110, and a second side of the protective portion 136 extends axially away from the stator core 102. The protective portion 136 is arranged circumferentially of the stator core 102 and positioned outside the windings 124 to achieve a protective arrangement. The annular protective portion 136 can protect the end of the stator core 102 where the windings 124 are disposed. When the stator assembly 100 is transported and collided, the protective portion 136 is impacted first, thereby preventing damage to the protective portion 136 and reducing damage to the windings 124.

[0106] This embodiment provides a stator assembly 100 . In addition to the technical features of the above embodiments, this embodiment further includes the following technical features.

[0107] like Figure 8 and Figure 9 As shown, the stator assembly 100 further includes a second frame 138, which is disposed on a side of the stator core 102 away from the first frame 108; Figure 4 and Figure 5 As shown, the slot paper 126 further includes a second positioning portion 140 . The second positioning portion 140 is connected to a side of the first body 128 away from the first positioning portion 130 and abuts against the second frame 138 .

[0108] In this embodiment, the stator assembly 100 further includes a second frame 138 , which is disposed on a side of the stator core 102 away from the first frame 108 , so as to arrange the second frame 138 so that the second frame 138 can protect the side of the stator core 102 away from the first frame 108 . The slot paper 126 also includes a second positioning portion 140, which is connected to the side of the first body 128 away from the first positioning portion 130 and abuts against the second frame 138 to facilitate installation of the second positioning portion 140. The second positioning portion 140 can limit the position of the second frame 138, thereby preventing the second frame 138 from moving relative to the stator core 102. This secures the second frame 138, protecting the side of the stator core 102 away from the first frame 108 and preventing deformation of the windings 124. The second positioning portion 140 limits the position of the second frame 138, simplifying its installation structure and reducing its difficulty. Furthermore, the slot paper 126 secures the second frame 138, ensuring that it does not interfere with assembly of the slot paper 126.

[0109] Specifically, the second frame 138 is an insulating frame.

[0110] Specifically, if Figure 10As shown, the first frame 108 is disposed on the first side of the stator core 102 in the axial direction, so that the first frame 108 can protect the first side of the stator core 102 in the axial direction.
