Embodiment Construction
[0021] The present invention will be described in detail below in conjunction with examples. It should be noted that, in the case of no conflict, the embodiments in the present application and the features in the embodiments can be combined with each other.
[0022] see Figure 1 to Figure 3 , the present invention provides a rotor, including a rotor core and a rotor shaft 100 sleeved in the rotor core. Wherein, a raised knurling 110 is provided on the area of the rotor shaft 100 mated with the rotor core, and the raised knurling 110 is not parallel to the centerline (axis) of the rotor shaft 100 .
[0023] The rotor of the present invention is mainly improved on the rotor shaft 100. On the basis of the traditional rotor shaft, the rotor shaft 100 of the present invention is provided with raised knurling 110 on the area matching the rotor core, without increasing the rotor Under the premise that it is difficult for the shaft 100 to enter the iron core, the interference and...
