Abstract In order to improve the reliability and fault-tolerant capability of the permanent magnet machine, a six-phase fault-tolerant flux switching permanent magnet machine(FTFSPM) is investigated in this paper. The machine presents not only benefits from high power density and good structural features of the permanent magnet flux switching(FSPM) machines, but also shows excellent fault-tolerant capability. Electromagnetic performance and fault-tolerant capability are analysed based on finite element analysis and experimental results. Fault-tolerant current control strategies are proposed in order to maintain a smooth output torque at single-phase fault state. By controlling current of q axis and zero sequence under synchronous rotating coordinates, torque ripple caused by open-circuit fault can be reduced and copper loss is considered at the same time. In condition of short-circuit fault, a compensation strategy based on fault decomposition is proposed. With compensating for short-circuit current and normal phase current loss respectively, complex online calculations are avoided. Experiments are taken on the prototype machine to verify the torque density, fault-tolerant capability of the machine and the proposed fault-tolerant control strategy.

Key words： Six-phase flux switching permanent magnet machine fault-tolerant torque ripple fault decomposition copper loss
