Research on Starting Process of a Novel Wound Rotor Line-Start Permanent Magnet Synchronous Motor
Squirrel-cage rotor line-start permanent magnet synchronous motor can not meet the heavy lifting, frequent starting conditions for the lifting requirements. In order to solve the difficult problem of starting caused by the squirrel-cage rotor line-start permanent magnet synchronous motor (LS-PMSM), a novel wound rotor line-start permanent magnet synchronous motor is proposed in this paper, which uses wound rotor to replace squirrel cage rotor. In this paper, the finite element analysis method is adopted to simulate and analyze the starting process of the motor, through reasonably determining the value of the external rotor resistance, the starting performance of the motor has improved greatly, and lead the motor smoothly into synchronous speed. The simulation results show the correctness and effectiveness of the research methods.
