The stator core assembly 2 is composed of three groups of stator core blocks 201. A slide rail 203 is fixedly mounted on one end surface of the stator core block 201, and a connecting groove 204 adapted to the slide rail 203 is opened on the other end surface of the stator core block 201.

[0025] The connection slot 204 cooperates with the slide rail 203 to enable the three groups of stator core blocks 201 to be spliced ​​into a cylindrical structure, thereby realizing the rapid assembly of the three groups of stator core blocks 201, and the stator core blocks 201 have a core unit 202;

[0026] A fastening assembly 3 is provided on the three groups of stator core blocks 201. The fastening assembly 3 is used to press the three groups of stator core blocks 201 into the stator housing 1 while being located on the chassis 103.

Three groups of abutting rods 302 are fixedly mounted on the restraining ring 301 at equal distances.

[0027] In the present application, a silicone pad is provided at the contact position between the limiting ring 301 and the three groups of stator core blocks 201 to prevent the limiting ring 301 from crushing the three groups of stator core blocks 201;

[0028] At the same time, a fixing plate 303 is installed on the inner wall of the stator housing 1. A plurality of sets of bolts 304 are connected to the fixing plate 303.

The buckle block 305 is suitable for pressing the supporting rod 302 into the slot, and a screw 306 is connected to the buckle block 305. The screw 306 is suitable for fixing the buckle block 305 on the fixing plate 303;

[0031] Working principle:

[0032] When using the stator core of the present technical solution, the three groups of stator core blocks 201 can be quickly assembled by adapting the slide rails 203 and the connecting grooves 204, and spliced ​​to form a circular column structure. The circular column structure composed of the above three groups of stator core blocks 201 is then placed on the chassis 103, and the limiting ring 301 is slid into the slot through the supporting rod 302. At the same time, the limiting ring 301 is pressed against the circular column structure composed of the three groups of stator core blocks 201, and the buckle block 305 is buckled onto the arch block to press the supporting rod 302 into the slot. The device is then fixed by tightening the screws 306 to achieve assembly and disassembly.
