矢量控制永磁同步电机失磁故障诊断方法研究
Research on the diagnosis method of demagnetization fault of permanent magnet synchronous motor based on vector control
摘要
Abstract
Based on the fact that the simulation model of permanent magnet synchronous motor (PMSM) vector control system of demagnetization fault was built based on Matlab/Simulink platform,the diagnosis method of demagnetization fault of PMSM was presented using the control mode of id=0.The ratio of the electromagnetic torque and the stator current was used as the magnetic failure factor,the ratio of the electromagnetic torque and the stator current in normal operation was used as the threshold.If the magnetic failure factor was less than the threshold, the magnetic field could be judged demagnetization fault.And according to the magnitude of the magnetic failare factor and the threshold value, the magnetic field could be judged the severity of the loss.The simulation results verified the validity of the method.关键词
