Abstract：The flux-switching permanent magnet (FSPM) motor exhibits the advantages of higher power density, higher efficiency and essentially sinusoidal back-EMF. In this paper, based on modeling of the FSPM motor, a new stator-flux-orientation control strategy under voltage space vector modulation (SVM) is investigated and implemented in a prototyped 12-slot/10-pole FSPM motor drive. In addition, due to the considerable influence of the dead-time on the output currents and torque characteristics, a predictive-current-compensation strategy is adopted to improve the performance. Experimental results on a 2kW prototyped FSPM motor drive based on the real-time dSPACE control platform verify the effectiveness of the control system. The control algorithm can be applicable for the controller design of other stator permanent magnet motors.
