Abstract: In order to enhance the performance of the four-phase faulttolerant permanent magnet motor (FTPMM) in normal conditions, a study is first made of the structure and principle of the fourphase FTPMM, and its mathematical model is presented to decouple its current, stator flux and torque. Then a novel voltage space vector pulse width modulation (SVPWM) method for the fourphase FTPMM driven by H bridges is proposed, and the insertion sequence of the zero vectors as well as the performance sequence of the coincidencesector is designed to facilitate its digital signal processor (DSP) implementation. To verify the effectiveness of the control strategy in normal conditions, some simulations and experiments are developed and the results show satisfactory static and dynamic performance of the system.
