摘要

To study the operation characteristics of the nine-phase PMSM(Permanent Magnet Synchronous Motor),this paper derived the Clarke transformation matrix of the nine-phase PMSM with the winding 3Y shifted by 20°via analyzing the harmonic subspace of the multi-phase PMSM,and further obtained its mathematical model under the rotating coordinate system.Then,a nine-phase PMSM based on the proposed model was built in SIMULINK and the operation mode of starting,braking and phase missing is simulated.The simulation results show that the nine-phase PMSM has good dynamic performance and steady-state performance,which also verifies the correctness and rationality of the motor model.
