Description
Technical Field
[0001] This utility model relates to the field of motor lamination technology, and more specifically, to a motor lamination that is easy to install. Background Technology
[0002] Electric motors, as indispensable power devices in modern industry and daily life, are widely used in various fields such as home appliances, automobiles, and industrial machinery. Motor laminations are key components forming the stator or rotor of a motor, and their performance and quality directly affect the overall performance of the motor. Motor laminations provide the mounting base for the motor windings.
[0003] A search revealed that patent application CN202021689675.9 discloses a motor lamination that is easy to install. The lamination includes a lamination body with winding teeth evenly distributed on its outer circumference. A winding groove is formed between adjacent winding teeth. A limiting baffle is provided at the end of each winding tooth. A positioning groove is provided on one side of the limiting baffle, and a positioning block is provided on the other side. Extension baffles are provided at both ends of the limiting baffle. This invention effectively prevents the copper coil from detaching from the winding teeth through the limiting baffle design, making the winding of the copper coil more stable and reliable. Furthermore, the extension baffles increase the overall length of the limiting baffle, allowing the winding teeth to wind more turns of copper wire without detaching, thus adapting to the needs of different motors. The extension baffles also increase the structural strength of the limiting baffle. The cooperation of the positioning groove and the positioning block ensures precise positioning and stacking between laminations, improving the structural stability of the stacked lamination assembly. However, the following drawbacks still exist: (1) The surface of the winding teeth of the motor lamination in the prior art is relatively smooth. During the winding process, the coil is easy to slide and shift, resulting in uneven and messy winding, which affects the electrical performance of the motor. (2) The existing motor laminations can only dissipate heat in the axial direction and are not convenient for circumferential heat dissipation, which makes it easy for heat to accumulate in the winding teeth and winding parts, resulting in poor heat dissipation effect. Utility Model Content
[0004] The purpose of this invention is to address the problems of slippage and poor heat dissipation in the winding of motor laminations.
[0005] To achieve the above-mentioned objectives, this utility model provides the following technical solution: The aforementioned problems can be improved by using motor laminations that are easy to install.
[0006] The present invention is as follows: The device includes a lamination body, on which a set of winding teeth are uniformly fixedly connected to the outer peripheral sidewall. An arc-shaped plate is fixedly connected to the outer end of each winding tooth. A set of protrusions are uniformly fixedly connected to both sidewalls of the winding teeth at equal intervals. A set of wire-guiding openings are uniformly opened on both sidewalls of the winding teeth at equal intervals. A set of heat dissipation openings are uniformly opened on the lamination body. Arc-shaped grooves are opened on both the upper and lower surfaces of the arc-shaped plate. Straight grooves connecting the heat dissipation openings and the arc-shaped grooves are opened on both the upper and lower surfaces of the lamination body and the winding teeth. Outer drainage grooves communicating with the arc-shaped grooves are opened on the outer periphery of both the upper and lower surfaces of the arc-shaped plate.
[0007] As a preferred technical solution of this utility model, a protruding ring is fixedly connected to the upper end face of the punch body, and a set of limiting posts are fixedly connected to the upper end face of the protruding ring.
[0008] As a preferred technical solution of this utility model, the lower end face of the punch body is provided with a groove that matches the convex ring, and a set of insertion holes that match the limiting post are evenly provided in the groove.
[0009] As a preferred technical solution of this utility model, a set of positioning holes are evenly opened on the lamination body, and the positioning holes are circular in shape.
[0010] As a preferred technical solution of this utility model, the winding teeth are provided with auxiliary holes that communicate with the upper and lower straight grooves.
[0011] As a preferred technical solution of this utility model, the number of arc-shaped grooves is the same as the number of winding teeth, and the wire guide opening is provided on the side of the protrusion.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In the solution of this utility model: 1. By setting up winding teeth, arc plates, protrusions and wire management openings, it is possible to better fix the winding during the winding process, prevent the winding from sliding and shifting, ensure the stability and reliability of the winding, make the winding process more orderly, avoid the winding from being messy and tangled, improve the winding efficiency and quality, and solve the problem of easy sliding and shifting of winding in the prior art. 2.

By using convex rings, limiting posts, slots, and insertion holes, precise stacking of motor laminations is achieved, ensuring complete alignment of the winding slots. At the same time, it can increase the contact area between the bottom lamination and its bottom mounting surface, improve installation stability and ease of installation, and solve the problem of poor stacking installation effect in existing technologies.

[0015] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.
[0016] like Figures 1 to 6As shown, this embodiment proposes a motor lamination that is easy to install, including a lamination body 1. A set of winding teeth 2 are uniformly fixedly connected to the outer peripheral sidewall of the lamination body 1. An arc-shaped plate 3 is fixedly connected to the outer end of each winding tooth 2. A set of protrusions 4 are uniformly fixedly connected to both sidewalls of the winding teeth 2. A set of wire management openings 5 are uniformly opened on both sidewalls of the winding teeth 2. A set of heat dissipation openings 6 are uniformly opened on the lamination body 1. Arc-shaped grooves 7 are opened on both the upper and lower surfaces of the arc-shaped plate 3. Straight grooves 8 connecting the heat dissipation openings 6 and the arc-shaped grooves 7 are opened on both the upper and lower surfaces of the lamination body 1 and the winding teeth 2. Outer drainage grooves 9 communicating with the arc-shaped grooves 7 are opened on the outer periphery of both the upper and lower surfaces of the arc-shaped plate 3. By using the uniformly distributed winding teeth 2 to define the coil winding area, the winding is arranged neatly and orderly, ensuring electromagnetic stability. During the conversion process, the magnetic field distribution is uniform. The protrusion 4 and the wire management port 5 help to better fix the coil during the winding process, prevent the winding coil from sliding and shifting, and ensure the stability and reliability of the winding coil. At the same time, it improves the stability of the coil installation, prevents the coil from shifting due to vibration during motor operation, and also makes the coil arrangement more compact, reduces the space occupied by the winding, increases the motor slot fill factor, and enhances electromagnetic performance. Axial heat dissipation can be achieved through the heat dissipation port 6. The heat dissipation port 6 and the arc-shaped slot 7 are connected by the straight slot 8. The heat dissipated by the winding coil flows to the heat dissipation port 6 and the arc-shaped slot 7 through the straight slot 8 respectively. The heat flowing to the arc-shaped slot 7 is further discharged to the outside through the external exhaust slot 9, thereby achieving circumferential heat dissipation, increasing the heat dissipation contact area, improving air flow, and improving the overall heat dissipation effect of the lamination.
[0017] in, like Figure 1 and Figure 3 As shown, a protruding ring 10 is fixedly connected to the upper end face of the lamination body 1, and a set of limiting posts 11 is fixedly connected to the upper end face of the protruding ring 10. The set of limiting posts 11 are evenly distributed along the circumference of the protruding ring 10. When multiple laminations are stacked, the protruding ring 10 is embedded in the slot 12 of the lower lamination to ensure the coaxiality after stacking, simplify the stacking operation of multiple laminations, reduce the assembly difficulty, and ensure the stacking accuracy.
[0018] like Figure 2 and Figure 3 As shown, the lower end face of the lamination body 1 is provided with a slot 12 that matches the convex ring 10. A set of insertion holes 13 that match the limiting post 11 are evenly provided in the slot 12. When stacking, the limiting post 11 is inserted into the insertion hole 13 of the lower lamination to ensure the positioning accuracy of the lamination stacking, avoid circumferential misalignment during the stacking process, realize the alignment of the winding space, and at the same time ensure the flatness of the bottom of the lamination body 1, enhance the contact area between the bottom lamination and the mounting surface, and improve the stability of the installation.
[0019] To further explain, such as Figure 1 and Figure 2As shown, a set of positioning holes 14 are evenly distributed on the lamination body 1. The positioning holes 14 are circular in shape. The positioning holes 14 facilitate the positioning and installation of the lamination, ensuring the installation accuracy. The winding teeth 2 are provided with auxiliary holes 15 that communicate with the upper and lower straight grooves 8. The auxiliary holes 15 increase the air circulation channel, which helps the heat to dissipate more quickly.
[0020] like Figure 1 and Figure 5 As shown, the number of preferred arc-shaped grooves 7 is the same as the number of winding teeth 2, and the wire guide opening 5 is set on the side of the protrusion 4; this ensures the uniformity of heat dissipation and also ensures the stability of winding.
[0021] Specifically, when using this easy-to-install motor lamination: first, install a charger at the target position and then install the lamination on top of it. The protruding ring 10 on the lower lamination is embedded in the slot 12 of the upper lamination, and at the same time, the limiting post 11 on the lower lamination is inserted into the insertion hole 13 on the upper lamination to achieve precise stacking and installation of the laminations. Then, the wire is wound on the winding teeth 2, the protrusion 4 and the wire guide 5 to make the coil arrangement tight and stable, effectively preventing the coil from sliding and shifting. During use, the heat emitted by the winding coil flows through the straight groove 8 to the heat dissipation port 6 and the arc groove 7 respectively. The heat flowing to the heat dissipation port 6 can dissipate heat along the axis, and the heat flowing to the arc groove 7 is further discharged outward through the external exhaust groove 9, thereby achieving circumferential heat dissipation, increasing the heat dissipation contact area, improving air flow, and improving the overall heat dissipation effect of the lamination.
[0022] All technical features in this embodiment can be freely combined according to actual needs.
[0023] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
