A PERMANENT-MAGNET HYSTERESIS HYBRID SYNCHRONOUS MOTOR FOR ELECTRIC VEHICLES

This paper presents the design, analysis, and PWM vector control of a hybrid permanent magnet hysteresis synchronous (PMHS) motor with a vie w to improve the performances of the motors for electric vehicle appli cation, This hybrid design combines the advantageous performance featu res of both the conventional hysteresis motors and the permanent magne t motors. Electrical equivalent circuits of the PMHS motor are develop ed for both the synchronous and asynchronous modes of operation, PWM v ector control simulation results for the motor drives are given, Final ly, a laboratory prototype hybrid hysteresis permanent magnet motor wa s built. Test results validate the superior performances of the new mo tor.
