Abstract

The invention provides a rotor structure, a motor and a rotor processing method. The rotor structure is provided with at least one pair of rotor poles, wherein each rotor pole is provided with a plurality of magnetic barrier layers. The rotor structure further comprises magnetic barrier layers, wherein each magnetic barrier layer comprises a slit groove, and two ends of the slit groove of at least part of the magnetic barrier layers are provided with filling grooves; and the slit grooves are symmetrically arranged relative to the quadrature axis of the rotor structure, and the filling grooves of the magnetic barrier layers are arranged along the direction of the direct axis of the rotor structure. The rotor structure provided by the invention solves the problem of poor starting capability of a self-starting synchronous reluctance motor in the prior art.

Description

technical field [0001] The invention relates to the field of motors, in particular to a rotor structure, a motor and a rotor processing method. Background technique [0002] The self-starting synchronous reluctance motor is based on the synchronous reluctance motor and combines the advantages of the asynchronous motor. It realizes self-starting through the asynchronous torque generated by the rotor guide bar, and realizes constant speed operation through the reluctance torque. [0003] Compared with the synchronous reluctance motor, the self-starting synchronous reluctance motor does not need to be driven by a frequency converter, the loss of the motor system is reduced, and the motor efficiency is improved; compared with the asynchronous motor, the self-starting synchronous reluctance motor can run at a constant speed with low rotor loss , the efficiency of the motor is high during operation; compared with the asynchronous start permanent magnet synchronous motor, no perman...
