Embodiment Construction

[0043] The present invention will be further described below in conjunction with the accompanying drawings.

[0044] Such as figure 1 , figure 2 , image 3The shown provides a single-bracket electric vehicle motor stator, including a stator core 1 and a bracket main body 2 matching with the inner circular surface of the stator core 1. The bracket main body 2 includes a cylindrical iron core mounting part 201, a disc Shaped support part 202 and shaft sleeve 203, one end of the cylindrical iron core installation part 201 is connected with the support part 202, and the other end of the iron core installation part 201 is provided with a flange 204 formed outwardly in the circumferential direction. The purpose of 204 is to fix the stator core 1 on the one hand, and to make the processing more convenient, because the flange 204 has been set on the core installation part 201, so when the stator core 1 is press-fitted, the flange Edge 204 plays the role of positioning and fixing. ...
