Abstract
The invention discloses a self-starting permanent magnet synchronous motor rotor. The rotor comprises a rotor body, a shaft and a permanent magnet, wherein the rotor body comprises a synchronous rotor and a mouse cage rotor; the synchronous rotor is sleeved on the shaft; end plates are arranged at the two ends of the synchronous rotor and sleeved with the shaft; the surface of the synchronous rotor is provided with a straight groove; the permanent magnet is arranged in the straight groove; the mouse cage rotor is sleeved on the synchronous rotor; and the outer circle of the synchronous rotor is in interference fit with the inner circle of the mouse cage rotor. The self-starting permanent magnet synchronous motor rotor improves labor productivity and cannot reduce the performance of a motor or damage the motor.
Description
Technical field
The present invention relates to a kind of rotor, particularly a kind of self-starting permanent-magnetic synchronous motor rotor.
Background technology
At present, the punching of the rotor of known self-starting permanent magnet synchronous motor is as a whole, and permanent magnet adopts the mode that is pressed into to be pressed onto in the groove of placing permanent magnet on the rotor; In order to be pressed into the placement permanent magnet, the starting cage of rotor just can not use skewed slot, and for the loss and the electromagnetic noise that reduce motor, improve starting performance and must adopt skewed slot, so can only in the stator core of motor, make stator iron core chute, be straight trough and rotor uses.Because skewed slot has been used in stator core, groove wire embedding degree is raise, strengthened the rule difficulty of stator winding, make the quality assurance of stator be lower than the stator of straight trough, and because stator uses skewed slot, make stator winding can not use automatic rule level rule, can only manual operation, reduce labor productivity, increased operator's technical ability requirement.Because the physical characteristic of permanent magnet is enbrittled, when using manual operation, easily make permanent magnet embrittlement and rotor is scrapped or permanent magnet cracks motor performance is descended.
Summary of the invention
Purpose of the present invention just is to provide a kind of labor productivity height, can not reduce the self-starting permanent-magnetic synchronous motor rotor of motor performance, can effectively address the above problem.
To achieve these goals, the technical solution used in the present invention is such: self-starting permanent-magnetic synchronous motor rotor of the present invention, comprise rotor body, axle and permanent magnet, described rotor body comprises synchronous rotor and cage rotor, synchronous rotor is socketed on the axle, the synchronous rotor two ends are provided with end plate, and end plate and axle sleeve connect, the synchronous rotor surface is provided with straight trough, described permanent magnet is arranged in the straight trough, described cage rotor is socketed on the synchronous rotor, and the interior round interference fit of synchronous rotor cylindrical and cage rotor.
As preferably, described cage rotor, is welded by cast aluminium and copper sliver by laminating the back groove skew certain angle by several cage rotor punchings again.
As preferably, described permanent magnet is by in the gluing straight trough that is connected on synchronous rotor, and four sides of permanent magnet are than the little 0.1mm of four sides of straight trough.
Compared with prior art, the invention has the advantages that: make the self-starting permanent-magnet synchronous motor rotor can adopt skewed slot starting cage, stator winding can adopt machinery rule automatically; The installation of permanent magnet need not to adopt the mode that is pressed into to be pressed into and makes it be difficult for embrittlement; Improve the efficient that motor is produced, to the dimension precision requirement reduction of permanent magnet.
