摘　　要：介绍了新型五相磁通切换永磁电机的结构和工作原理。针对其电感较大的特点,提出了一种新型容错控制策略,该方法通过控制磁动势保持不变,并考虑了电机故障条件下磁阻转矩的作用。建立了电机驱动系统的瞬态场路耦合仿真模型,并通过仿真结果验证了容错控制策略的正确性,与传统容错控制策略相比,该方法可以提高故障条件下电机的转矩性能。The configuration and the operation principle of a new five-phase flux-switching permanent magnet motor were presented. Due to its large inductance, by keeping the magnetic motive force invariant, a new fault-tolerant control strategy was proposed, in which the reluctance torque was considered. A co-simulation model of the proposed motor drive was developed for verification. The co-simulated results verify the effec- tiveness of the proposed control strategy. Compared the conventional one, the proposed fault-tolerant control strategy can improve the torque performance under the faulty condition.
