During zero and low-speed conditions, the magnetomotive force (MMF) harmonic present in the air gap of a five phase self-excited synchronous motor (FP-SESM) is not strong enough to produce the necessary excitation current needed for torque output. To solve the problem of torque output, it is necessary to introduce an additional high-frequency current with a different phase than the fundamental current. The traditional field-oriented control (FOC) strategy cannot achieve decoupling of fundamental and high-frequency currents. This paper proposes a FOC strategy for FP-SESM injected with high-frequency current. This strategy uses two different Clarke transforms to decouple the high-frequency current from the fundamental current. The simulation results show that the proposed FOC strategy has a good control effect on the operation of the motor.
