The connection is convenient and simple. In particular, the socket and the plug are elastically fitted to improve the stability and reliability of the connection.

[0036] Please refer to Figures 1-4 Both the front PCB board 400 and the rear PCB board 500 are provided with several soldering holes 520, through which the wire ends 310 and 320 are soldered. The soldering holes 520 allow the wire ends 310 and 320 to pass through for soldering, enabling soldering operations to be performed on the exposed surfaces, thus facilitating soldering.

[0037] Please refer to Figure 1 -、 Figure 2 and Figure 4 It also includes a housing 600, which has mounting holes 610 for accommodating the stator core 100, the front PCB board 400, and the rear PCB board 500. The mounting holes 610 can assist in the installation and positioning of the front PCB board 400 and the rear PCB board 500.

[0038] Please refer to Figure 1 and Figure 2 The front PCB board 400 has a first height gap 611 between its front end face and the housing 600, and the rear PCB board 500 has a second height gap 612 between its rear end face and the housing 600. Setting these height gaps can protect the PCB boards.

[0041] Please refer to Figure 3 Both the front PCB board 400 and the rear PCB board 500 are supported on the end face of the stator frame 200. The frame is insulated, and the support of the frame ensures the insulation between the PCB board and the stator core 100.

[0042] Please refer to Figure 4 The stator core 100 is formed by splicing several stator chip units along the circumferential direction, and each stator chip unit is formed by stacking several layers of stator chips. That is, the spliced ​​stator core 100 is easy and simple to produce, and facilitates the winding of the coil 300.
