Abstract
The utility model discloses a rotor of a self-starting permanent-magnet synchronous motor, wherein the rotor comprises a rotor main body and a permanent magnet. The rotor main body includes a synchronous rotor and a cage rotor; a straight flute is arranged at the surface of the synchronous rotor and the permanent magnet is arranged inside the straight flute; and the cage rotor is sleeved on the synchronous rotor; and the excircle of the synchronous rotor and the inner circle of the cage rotor are in an interference fit. And end rings are respectively arranged at two ends of the rotor main body; and the centers of gravity of the two end rings are respectively arranged at opposite sides of the shaft center of the rotor main body. According to the utility model, the rotor has advantages of simple structure and high labour productivity; and besides, the motor performance is not reduced.
Description
Technical field
The utility model relates to a kind of synchronous electric motor 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, be prone to make permanent magnet embrittlement and rotor scrapped or permanent magnet cracks motor performance is descended.
Summary of the invention
It is a kind of simple in structure that the purpose of the utility model just is to provide, and labor productivity is high, 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 scheme that the utility model adopts is such: the self-starting permanent-magnetic synchronous motor rotor of the utility model, comprise rotor body and permanent magnet, and said rotor body comprises synchronous rotor and cage rotor; The synchronous rotor surface is provided with straight trough; Said permanent magnet is arranged in the straight trough, and said cage rotor is socketed on the synchronous rotor, and the interior round interference fit of synchronous rotor cylindrical and cage rotor; The rotor body two ends are respectively arranged with end ring, and the center of gravity of two end ring is arranged at the opposition side in rotor body axle center respectively.
As preferably, be provided with baffle plate between said end ring and the rotor body.
As preferably, have riveted holes on the said end ring, end ring passes riveted holes through riveting column and is fixed on the rotor body.
As preferably, said permanent magnet is through 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 advantage of the utility model is: rotor body is made up of synchronous rotor and cage rotor, makes the self-starting permanent-magnet synchronous motor rotor can adopt skewed slot starting cage, and 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; The rotor body two ends are provided with end ring, have the function of balance center of gravity, can effectively form whole dynamic equilibrium.
