Embodiment
The present invention is further detailed explanation with reference to the accompanying drawings and detailed description.
As shown in figs. 1 to 6, the present invention includes cage rotor 12, and it also includes stator core 3；The both ends of cage rotor 12
It is installed on the inside of stator core 3 again after fore bearing 13, rear bearing 14 is installed respectively；Stator core 3 is by being coaxially disposed
Steel plate punching and stator punching group composition；Steel plate punching is two, and two steel plate punchings are folded between stator punching group；
Steel plate punching is respectively arranged at stator core 3 close to the position at both ends；
Steel plate punching and stator punching group are circle；Correspondingly opened up in the outer circumference of steel plate punching and stator punching group
There is cramp groove 7, steel plate punching and stator punching group are fixedly clamped by the cramp being placed on cramp groove 7；Cramp is more to be multiple
Individual cramp is uniformly arranged in the outer circumference of stator core 3.The diameter of steel plate punching is more than the diameter of stator punching group；Steel plate
In punching multiple positioning holes 9 are offered on the circumference of stator punching group.
The specific mounting means of the present invention is described in detail below by specific embodiment：
Embodiment one,
Stator punching and the punching of two panels steel plate are repeatedly pressed in order first, and clamped with cramp, forms the stator of motor
Iron core；Then it is embedded in winding in stator core and makees dipping lacquer processing, is reloaded into cage rotor of the both ends with bearing and positioned at fixed
