Description

Technical Field

[0001] This utility model relates to an assembled motor stator, belonging to the field of motor stator technology. Background Art

[0002] To facilitate repair of electronic stators when coils burn out, Chinese patent document CN114825686A discloses a split, easily replaceable motor stator structure and assembly method. This method divides the stator into multiple stator component mechanisms that can be spliced ​​together. It uses limiting components to fix iron sheets, but this requires drilling holes in the iron sheets, which not only complicates processing but also easily affects the strength of the iron sheets, and consequently the strength of the iron core. To solve these problems, this utility model provides a spliced ​​motor stator. Utility Model Content

[0003] To address the problems existing in the prior art, this utility model provides a modular motor stator with a fixing frame that clamps the iron core plates to separate the coil from the iron core, facilitating processing and assembly without affecting the strength of the iron plates.

[0004] To achieve the above objectives, this utility model adopts the following technical solution: a modular motor stator, comprising multiple modular modules, which are assembled together by splicing rings to form a stator. The splicing rings allow the multiple modular modules to be stably spliced ​​together, thereby ensuring the stability of the assembled stator. Each modular module includes an iron core and a fixing frame. The fixing frame is used to limit the iron core and support the coil. The iron core is composed of multiple iron pieces. The fixing frame is sleeved on the outside of the iron core, which can limit the multiple iron pieces and keep the iron core stable. Moreover, when winding the coil, the coil can be directly wound onto the fixing frame. The fixing frame also serves to separate the coil from the iron core, thus facilitating coil winding. One end face of the iron core is convex and the other end face is concave. During splicing, adjacent iron cores can be interlocked, which can better ensure the stability of the assembled stator.

[0005] Preferably, the fixing frame includes an upper frame and a lower frame, the inner end faces of the upper frame and the lower frame are engaged with each other to surround and fix the iron core, the end of the upper frame and the lower frame that is close to each other is the inner end, and the upper frame and the lower frame surround the iron core from above and below, respectively, so that they can be connected together with the iron core.

[0006] Preferably, limiting plates are fixedly connected to both sides of the outer end face of the upper frame and the lower frame. The limiting plates can limit the coil wound on the fixed frame, thereby preventing the coil from falling off the fixed frame.

[0007] Preferably, the limiting plate is provided with a clamping groove for fixing the end of the coil. The clamping groove can fix the end of the coil, thereby facilitating assembly.

[0008] Preferably, the clamping groove is U-shaped, with the sidewall of its opening end being inwardly tapered, and the opening of the clamping groove being a flared shape with a narrow inner frame. With the above-mentioned configuration, the clamping groove can tightly clamp the end of the coil by relying on the elastic deformation generated by the limiting plate, thereby fixing the end of the coil.

[0009] Preferably, both the upper and lower frames are U-shaped. A plug is fixedly connected to the end face of the open end of the upper frame, and protrusions are fixedly connected to both sides of the plug. A slot adapted to the plug is opened on the end face of the open end of the lower frame. When the upper and lower frames are spliced ​​together, the plug is inserted into the slot. The plug is engaged with the slot through the protrusions. The size of the slot is adapted to the size of the plug. The protrusions and the slot have an interference fit, which allows the upper and lower frames to be stably spliced ​​together.

[0010] Preferably, a slot is provided on the lower side of the insert block. The slot allows the insert block to deform when the protrusion is pressed by the slot wall, thereby allowing the protrusion to better engage with the slot.

[0011] Preferably, the splicing ring includes multiple fixing strips. When multiple assembly modules are spliced ​​together, the multiple fixing strips can form a complete ring. The fixing strips are fixedly connected to the fixing frame, and adjacent fixing strips are connected to each other by screws. After the screws connect multiple fixing strips together, the fixing strips can stably maintain the ring shape, thereby making the stator formed by splicing stable.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. The iron core is held in place by a fixing frame, which facilitates installation. When winding the coil, the fixing frame can also separate the coil from the iron core, thus facilitating processing and assembly.

[0014] 2. Inserts are provided on the upper frame and slots are provided on the lower frame. The inserts are provided with protrusions and slots, which can better engage the inserts with the slots and splice the upper and lower frames together.

[0015] 3. Limiting plates are set on the upper and lower frames, and clamping grooves are set on the limiting plates to facilitate the fixing of the ends of the coil. Attached Figure Description

[0022] The present invention is illustrated below with specific embodiments, but these are not intended to limit the scope of the invention.

[0023] Example 1

[0024] In this embodiment, a modular motor stator is provided, such as... Figure 1 and Figure 2 As shown, the system includes multiple assembly modules 1, which are interconnected by splicing rings 4 to form a stator. The splicing rings 4 ensure stable connection of the multiple assembly modules 1, thus maintaining the stability of the assembled stator. Each assembly module 1 includes an iron core 2 and a fixing frame 3. The fixing frame 3 is used to constrain the iron core 2 and support the coils. The iron core 2 is composed of multiple iron sheets spliced ​​together, such as... Figure 2 As shown, the fixing frame 3 is sleeved on the outside of the iron core 2, which can limit multiple iron pieces and keep the iron core 2 stable. Moreover, when winding the coil, the coil can be directly wound on the fixing frame 3. The fixing frame can also separate the coil from the iron core 2, thus making it easier to wind the coil. One end face of the iron core 2 is convex and the other end face is concave. When splicing, two adjacent iron cores 2 can be inserted into each other, which can make the stator after splicing better maintain stability.

[0025] like Figure 3 As shown, the fixing frame 3 includes an upper frame 301 and a lower frame 302. The inner end faces of the upper frame 301 and the lower frame 302 are interlocked and surround the iron core 2 to fix it. The end of the upper frame 301 and the lower frame 302 that is close to each other is the inner end. The upper frame 301 and the lower frame 302 surround the iron core 2 from above and below, respectively, so that they can be connected together with the iron core 2.

[0026] The clamping groove 304 is U-shaped, with its sidewall at the opening end being inwardly tapered. The opening of the clamping groove 304 is a flared shape with a narrow inner frame. With the above-mentioned configuration, the clamping groove 304 can tightly clamp the end of the coil by relying on the elastic deformation generated by the limiting plate 303, thereby fixing the end of the coil.

[0027] like Figure 3 and Figure 5 As shown, both the upper frame 301 and the lower frame 302 are U-shaped. A plug 305 is fixedly connected to the end face of the open end of the upper frame 301, and protrusions 306 are fixedly connected to both sides of the plug 305. A slot 307 adapted to the plug 305 is provided on the end face of the open end of the lower frame 302. When the upper frame 301 and the lower frame 302 are spliced ​​together, the plug 305 will be inserted into the slot 307. The plug 305 is engaged with the slot 307 through the protrusions 306. The size of the slot 307 is adapted to the size of the plug 305. The protrusions 306 and the slot 307 are in an interference fit relationship, which can stably splice the upper frame 301 and the lower frame 302 together.

[0028] The lower side of the insert 305 is provided with a slot 308. The slot 308 allows the insert 305 to deform when the protrusion 306 is pressed by the groove wall of the slot 307, so that the protrusion 306 can better engage with the slot 307.

[0029] The splicing ring 4 includes multiple fixing strips 401, such as Figure 2 As shown, when multiple assembly modules 1 are assembled together, multiple fixing strips 401 can form a complete ring. The fixing strips 401 are fixedly connected to the fixing frame 3, and adjacent fixing strips 401 are connected to each other by screws. After the screws connect multiple fixing strips 401 together, the fixing strips 401 can stably maintain the ring shape, thereby making the stator formed by the assembly stable.

[0030] Example 2

[0031] Based on Embodiment 1, in order to better wind the coil, limiting plates are provided on the upper and lower frames, specifically as follows:

[0032] like Figure 4 As shown, both sides of the outer end face of the upper frame 301 and the lower frame 302 are fixedly connected to limit plates 303. The limit plates 303 can limit the coil wound on the fixed frame 3, thereby preventing the coil from falling off the fixed frame 3.

[0033] The limiting plate 303 is provided with a clamping groove 304 for fixing the end of the coil. The clamping groove 304 can fix the end of the coil, thereby facilitating assembly.

[0034] Finally, it should be noted that the above embodiments are only used to illustrate and not limit the technical solutions of this utility model. Although this utility model has been described in detail with reference to the above embodiments, those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model without departing from the spirit and scope of this utility model.
