【Abstract】 This paper presents the mathematical model of six-phase permanent magnet synchronous motor(PMSM) in the six-phase static references and the two-phase synchronous rotating references based on the method of space vector decoupling.In Matlab/Simulink,the simulation model of the six-phase PMSM vector control system was established.The simulation results testify the validity of the mathematical and simulation model and indicate that the six-phase PMSM vector control system has the advantage of fast dynamic response,high static precision and small rippling torque.更多还原
