The motor has a rotor and a stator, wherein the stator can be formed by piecing together a plurality of stator blocks into a circle, and windings are set on each stator block.

[0027] The present application is further described in detail below by means of specific embodiments in conjunction with the accompanying drawings. Similar elements in different embodiments are numbered with associated similar elements. In the following embodiments, many detailed descriptions are provided to enable the present application to be better understood. However, those skilled in the art will readily appreciate that some of the features may be omitted in different circumstances, or may be replaced by other elements, materials, or methods.

This is to avoid the core portion of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail. They can fully understand the related operations based on the description in the specification and the general technical knowledge in the art.

[0028] In addition, the features, operations, or characteristics described in the specification may be combined in any appropriate manner to form various embodiments. Furthermore, the steps or actions in the method description may be reordered or adjusted in a manner readily apparent to those skilled in the art. Therefore, the various sequences in the specification and drawings are provided solely for the purpose of clearly describing a particular embodiment and are not intended to be mandatory, unless otherwise specified.

[0029] Component numbers used herein, such as "first" and "second," are used solely to distinguish the components being described and do not convey any sequential or technical meaning. References to "connection" and "coupling" herein, unless otherwise specified, include both direct and indirect connections (couplings).

[0030] During the manufacturing process of the stator, the process of winding to form the winding needs to be completed on the winding equipment, and the process of assembling the stator segments into a circle needs to be completed by another assembling device, which makes the operation in the stator manufacturing process more complicated, prolongs the production cycle, and has low production efficiency. In addition, when assembling the circle, the device is fixed from the outside of the stator, and the inner diameter size of the stator will be affected by the consistency of the stator segments, resulting in the inner diameter size of the stator cannot be guaranteed, reducing the controllability of the air gap size, and affecting the performance of the motor. The stator assembling device in the present application can realize the winding and assembling of the stator through the radial movement of the movable bracket, and no disassembly and replacement steps are required during the manufacturing process, which solves the above problems and improves production efficiency. In addition, the clamping member of the movable bracket clamps and fixes from the inside of the stator, which can ensure the inner diameter size of the stator, increase the controllability of the air gap size, and improve the performance of the motor.

[0031] See also Figures 1 to 7 The embodiment of the present application provides a stator circle assembly device, including a guide rail plate 1, a movable bracket 2 and other functional components that exist as needed, which are described in detail below.

[0032] like Figure 1-Figure 5 In this embodiment, a plurality of guide rails 11 are provided on the circumferential direction of the guide rail disc 1, and each guide rail 11 is extended along the radial direction of the guide rail disc 1; a movable bracket 2 is slidably mounted on each guide rail 11, and the movable bracket 2 includes a support member 22 and a clamping member 21 connected to the support member 22. The support member 22 enables each movable bracket 2 to move on the corresponding guide rail 11, and each clamping member 21 is used to clamp the stator block 4 from the inner side of the stator.

[0033] It is understood that in this embodiment, the circumferential direction of the guide rail disc 1 is the circumferential direction of the guide rail disc 1, and the radial direction of the guide rail disc 1 is the linear direction along the diameter or radius. The guide rails 11 are arranged to extend radially along the guide rail disc 1, so that the sliding of the movable bracket 2 on the guide rails 11 is radial sliding along the guide rail disc 1. In some embodiments, when the widths of the stator segments 4 in the stator are the same, the guide rails 11 can be evenly distributed along the circumference of the guide rail disc 1, that is, the central angles formed between two adjacent guide rails 11 are equal. In this embodiment, the spacing between two adjacent guide rails 11 can be the same as the spacing between two adjacent stator segments 4 in the stator; alternatively, when the widths of the stator segments 4 in the stator are different, the guide rails 11 can also be unevenly distributed along the circumference of the guide rail disc 1. In this embodiment, each clamping member 21 is disposed on the same side of the guide rail disc 1 on opposite axial sides to achieve circular alignment of the stator segments 4. For example, when the axial direction of the guide rail disc 1 is parallel to the vertical direction, each clamping member 21 can be disposed on the upper side of the guide rail disc 1, or each clamping member 21 can be disposed on the lower side of the guide rail disc 1. In this embodiment, there is no specific limitation on the materials of the guide rail disc 1 and the movable bracket 2; for example, they can be made of metal or plastic.

[0034] After the clamping member 21 clamps and fixes the unwound stator segments 4 from the inner side of the stator, the bracket 2 is slid along the guide rail 11 to move the stator segments 4 toward the center of the guide rail plate 1 or away from the center of the guide rail plate 1. Figure 6 As shown, the movable brackets 2 are arranged in a circular pattern to pre-assemble the stator segments 4, and then the movable brackets 2 are sequentially moved away from the center of the guide rail plate 1, as shown in FIG. Figure 7 As shown, the stator block 4 on the removed mobile bracket 2 can be wound. After the winding is completed, it is moved back to its original position and the next mobile bracket 2 is removed. After the winding of all stator blocks 4 is completed, the two adjacent stator blocks 4 are fixed, and the clamping of the stator block 4 by the clamping member 21 is released to remove the stator. Because the adjacent stator blocks 4 are in the pre-circular position during winding, the winding will not be interfered with by the adjacent stator blocks 4, thereby realizing the winding and circular processing of the stator by the circular device. There is no need for disassembly and replacement steps during the production process, which can reduce the difficulty of operation, shorten the production cycle, and improve production efficiency. In addition, the clamping member 21 is clamped and fixed from the inside of the stator to ensure the inner diameter size of the stator, increase the controllability of the air gap size, and improve the performance of the motor. In this embodiment, the inner diameter of the stator is the diameter of the inner hole in the stator for assembling the rotor, the inner side of the stator is the hole wall of the inner hole, and the outer side of the stator is the side wall of the outer circumference of the stator.

[0035] In one embodiment, Figure 1As shown, the support member 22 is disposed in the radially inward region of the guide disc 1, and the clamping member 21 is disposed in the radially outward region of the guide disc 1. In this embodiment, the radially inward region of the guide disc 1 is the side of the guide disc 1 radially closer to the center of the guide disc 1, and the radially outward region of the guide disc 1 is the side of the guide disc 1 radially closer to the outer circumference of the guide disc 1. The clamping member 21 is disposed in the radially outward region of the guide disc 1, facilitating its clamping of the stator segments 4 from the inner side of the stator. The support member 22 is disposed in the radially inward region of the guide disc 1, thereby preventing the support member 22 from interfering with the clamping member 21's clamping of the stator segments 4.

[0036] In some embodiments, a plurality of positioning blocks are provided on the guide rail disc 1, and a corresponding positioning block is provided on each guide rail. The positioning blocks enclose a ring, and the outer diameter of the ring is the same as the inner diameter of the stator. When forming a circle, the mobile bracket 2 is moved until the mobile bracket 2 touches the positioning block, and the mobile bracket 2 is moved into place. By moving each mobile bracket 2 in sequence according to this method, the mobile bracket 2 can be distributed in a circle to complete the circle. In some application scenarios, a positioning ring can also be directly provided on the guide rail disc 1. The positioning ring can be provided with multiple different diameters according to the specifications of the stator. When forming a circle, the positioning ring of the corresponding diameter is fixed on the guide rail disc 1, and the center of the positioning ring coincides with the center of the guide rail disc 1. The mobile bracket 2 is moved until the mobile bracket 2 touches the positioning ring, and the mobile bracket 2 is moved into place. By moving each mobile bracket 2 in sequence according to this method, the mobile bracket 2 can be distributed in a circle to complete the circle. The positioning of the mobile bracket 2 is not limited to the above two methods, and other methods that can achieve the positioning of the mobile bracket 2 can also be used. In this embodiment, the movement of the movable brackets 2 can be manually driven, pushed or pulled manually using a tool, or electrically driven. In some embodiments, to facilitate the movement of the movable brackets 2, each support member 22 may be provided with a radial extension (not shown) on the side proximal to the outer circumference of the guide rail plate 1. This radial extension is located at the lower end of the clamping member 21 and does not interfere with the clamping portion 212's grip on the stator segment 4. The movable brackets 2 can be moved by applying force to push or pull the radial extension.

[0037] In one embodiment, Figure 2-Figure 4The clamping member 21 includes a vertical arm 211 and a clamping portion 212 respectively provided at both ends of the vertical arm 211. The vertical arm 211 is connected to the support member 22. The clamping portion 212 is provided in the radially outward area of ​​the guide rail disc 1. The clamping portion 212 is used to correspond to the end of the stator block 4. The clamping portions 212 at both ends respectively correspond to the two ends of the stator block 4 for clamping, which better fixes the stator block 4 on the clamping member 21. The clamping portion 212 in this embodiment can be a claw, and a groove can be provided on the stator block 4. The position of the claw corresponds to the position of the groove on the stator block 4. When clamping, the claw is inserted into the corresponding groove to fix the stator block 4. Then, the claw is moved out of the groove to release the clamping. The groove on the stator block 4 can be provided on the skeleton of the stator block 4, or on the stator core of the stator block 4. In this embodiment, the shape of the claw can be adapted to the shape of the groove on the stator block 4. The clamping portion 212 in this embodiment may also be other structures, such as a magnet, which can be used to fix the stator segment 4 from the inner side of the stator by adsorption. In some embodiments, in order to prevent the circular shape from being affected by the width of the vertical arm 211, the width of the vertical arm 211 can be smaller than the width of the stator segment 4. In this embodiment, the width of the vertical arm 211 is the width of the vertical arm 211 in the circumferential direction of the guide plate 1, and the width of the stator segment 4 is the width of the stator segment 4 in the circumferential direction of the stator.

[0038] In one embodiment, to allow the two clamping portions 212 to be adjustable so that the stator sizing device can accommodate different stator sizes, the vertical arm 211 in this embodiment includes a telescopic rod 216 with adjustable length and fixed blocks 213 located at each end of the telescopic rod 216. Each fixed block 213 is assembled with a clamping portion 212 via a slide rail 215. The clamping portion 212 moves on the slide rail 215 to adjust the extension length of the clamping portion 212. The extension and contraction of the telescopic rod 216 can adjust the spacing between the clamping portions 212 at each end. The clamping portion 212 slides on the slide rail 215 to adjust the extension length of the clamping portion 212 to clamp stator segments 4 of different sizes. In this embodiment, the length of the telescopic rod 216 can be adjusted by pins or screws on the telescopic rod 216 after extension and contraction. Similarly, the clamping portion 212 can also be fixed by pins or screws after sliding into position. In some application scenarios, the distance between the two clamping parts 212 can also be a fixed distance, and the clamping parts 212 can also be fixed at both ends of the vertical arm 211, and can be set according to needs.

[0039] In one embodiment, the mobile bracket 2 further includes a slide 214, and the vertical arm 211 is connected to the support member 22 via the slide 214. The slide 214 is provided with a through hole, and the vertical arm 211 is slidably assembled in the through hole. The vertical arm 211 can be slidably adjusted relative to the slide 214, thereby adjusting the height of the two clamping parts 212 relative to the guide rail plate 1, so as to adjust the height to a suitable position, which is convenient for winding processing and fixing processing between adjacent stator blocks 4. In some embodiments, after the vertical arm 211 is slidably adjusted relative to the slide 214 into place, it can also be fixed by screws or pins. In some embodiments, the mobile bracket 2 may not include the slide 214, and the vertical arm 211 can be directly connected and fixed to the support member 22.

[0040] In one embodiment, Figure 3 As shown, a connecting shaft 23 is provided on the support member 22, and the connecting shaft 23 is connected to the slide 214 so that the clamping member 21 can rotate around the axis of the connecting shaft 23. Because the clamping member 21 is rotatable, winding can be performed by directly rotating the clamping member 21 during winding, which facilitates the production of the winding. In this embodiment, the connecting shaft 23 can be a fixed shaft provided on the support member 22, and the slide 214 can be rotatably provided on the connecting shaft 23, and the clamping member 21 can be rotated during winding to achieve winding; or the connecting shaft 23 can be rotatably provided on the support member 22, and the connecting shaft 23 is fixedly connected to the motor shaft of a motor, and the slide 214 is fixedly connected to the connecting shaft 23, and the rotation of the motor shaft can drive the slide 214 to rotate, thereby achieving the automatic rotation of the clamping member 21 for winding. In some embodiments, in order to achieve rotational balance of the clamping member 21, the connecting shaft 23 can be connected to the center of the slide 214, and a mounting hole can be set at the center of the slide 214. The connecting shaft 23 can be rotatably assembled in the mounting hole to achieve a rotatable setting of the clamping member 21.

[0041] In one embodiment, distance sensors are provided at both ends of the slide 214 to adjust the distance of the vertical arm 211 relative to the slide 214. The distance sensor can detect the distance between the end of the slide 214 and the end of the vertical arm 211, thereby facilitating the adjustment and control of the length of the vertical arm 211 on one side of the slide 214 to be equal to the length of the vertical arm 211 on the other side of the slide 214. After being equal, the center of the vertical arm 211 can also coincide with the axis of the connecting shaft 23, making the rotation more balanced. In some application scenarios, a distance sensor may not be provided, and adjustment can be performed directly using a ruler. In order to facilitate detection, a component for sensing by the distance sensor may be provided at the end of the vertical arm 211. The component may be the above-mentioned fixed block 213, or other structures provided at the end of the vertical arm 211, such as a protrusion provided at the end of the vertical arm 211, or a pin provided, etc.

[0042] In one embodiment, Figure 5The guide rail disc 1 includes an outer ring 12 and a center body 13. The center body 13 is located at the center of the outer ring 12. The guide rail 11 is arranged along the radial direction of the outer ring 12. One end of the guide rail 11 is connected and fixed to the outer ring 12, and the other end is connected and fixed to the center body 13. The guide rail disc 1 has a simple structure, and there is a hollow structure between adjacent guide rails 11, which saves materials and reduces costs. In order to facilitate the installation of the mobile bracket 2, at least one end of the guide rail 11 is detachably connected. For example, the guide rail 11 and the outer ring 12 are detachably connected. During assembly, the support member 22 is first assembled on the guide rail 11, and then the guide rail 11 is connected and fixed to the outer ring 12; or the guide rail 11 and the center body 13 are detachably connected. During assembly, the support member 22 is first assembled on the guide rail 11, and then the guide rail 11 is connected and fixed to the center body 13. In this embodiment, the outer ring 12 or the central body 13 may be in the form of two transversely cut halves. During assembly, the two halves are brought together to clamp and secure the guide rails 11, thereby forming a connection and fixation between the outer ring 12 or the central body 13 and the guide rails 11, thereby facilitating the assembly of the mobile bracket 2. In some embodiments, the guide rail plate 1 may also have other structures, such as including a circular base plate with a plurality of guide rails 11 disposed on its upper surface.

[0043] In one embodiment, the end of the support member 22 closest to the guide rail disc 1 is slidably assembled with the guide rail 11, and the end of the support member 22 away from the guide rail disc 1 is connected to the clamping member 21. The support of the support member 22 can maintain a certain distance between the clamping member 11 and the guide rail disc 1, facilitating the winding process on the stator segment 4.

[0044] In one embodiment, the guide rail 11 is cylindrical, and a through hole 221 is provided on the support member 22. The guide rail 11 is slidably assembled in the through hole 221 to form a guide. The cylindrical guide rail 11 has a simple structure and is easy to process. The cylindrical shape in this embodiment can be cylindrical, elliptical, square, etc. When it is cylindrical, the support member 22 needs to be circumferentially limited to prevent the support member 22 from rotating around the guide rail 11. In some embodiments, a sliding guide can also be formed between the guide rail 11 and the support member 22 through other structures. For example, the guide rail 11 is in a "T" shape, and a "T"-shaped groove corresponding to the "T" structure is provided on the support member 22. The guide rail 11 with the "T"-shaped structure is assembled in the "T"-shaped groove to form a sliding guide.

[0045] In one embodiment, the stator circle assembly device further includes a base 3, on which is provided a guide post 31. The axis of the guide post 31 is parallel to the axis of the guide rail disc 1, and the guide rail disc 1 is slidably mounted on the guide post 31. The base 3 can be used to fix the stator circle assembly device on a workbench. The guide rail disc 1 can slide up and down along the guide post 31, thereby adjusting the height of the movable bracket 2, that is, the height of the stator segment 4 clamped on the movable bracket 2 can be adjusted to adapt to different application scenarios and the winding and circle assembly processing of different stators. In this embodiment, a center hole can be provided in the center of the guide rail disc 1, and the guide post 31 can be slidably mounted in the center hole. The guide rail disc 1 and the guide post 31 are fixed by pins or screws. When the guide rail disc 1 includes a center body 13, the center hole can be provided on the center body 13. In some application scenarios, the guide post 31 can also slide with the outer circumference of the guide rail disc 1. The specific structure can be selected according to actual needs. Alternatively, in some embodiments, the base 3 can be omitted and the stator circle assembly device can be directly fixed to the workbench via the guide rail disc 1.

[0046] The stator circular assembly device provided in the above embodiment has a movable bracket 2 that is slidably assembled on a guide rail 11. When manufacturing the stator, the unwound stator segments 4 are first clamped and fixed from the inside of the stator using a clamping member 21. The movable bracket 2 is then slid on the guide rail 11, allowing each movable bracket 2 to be distributed in a circular pattern to pre-circularize the stator segments 4. The movable brackets 2 are then removed one by one, and the stator segments 4 on the removed movable brackets 2 are wound. After all stator segments 4 are wound, the two adjacent stator segments 4 are fixed. This completes the stator winding and circular assembly process, eliminating the need for disassembly and replacement steps during the manufacturing process, reducing operational difficulty, shortening the production cycle, and improving production efficiency. Furthermore, the clamping member 21 clamps the stator segments 4 from the inside of the stator. During circular assembly, the positions of the movable brackets 2 are adjusted so that they are distributed in a circular pattern, ensuring the inner diameter of the stator. The inner diameter of the stator is not affected by the consistency of the stator segments 4, increasing the controllability of the air gap size, and improving motor performance.

[0047] The above specific examples are used to illustrate the present application, which is only used to help understand the present application and is not intended to limit the present application. For those skilled in the art of the present application, based on the concept of the present application, they can also make some simple deductions, modifications or substitutions.
