摘　　要：以高可靠航天机电伺服系统为应用背景,为了得到适合航天应用的高可靠性多相容错电机最优方案,提出四相、五相、六相3种容错电机方案,并利用有限元仿真分析对3种方案的磁密、转矩、转矩波动、容错性能等进行对比分析。四相电机性能较差,不满足指标要求;五相电机与六相电机性能接近,但五相电机容错运行后性能更好,而且五相电机相较于六相电机更加节省硬件资源。五相十槽十二极构型电机是适用于航天应用的多相容错电机最优方案。In this paper, based on the application background of high reliability aerospace electromechanical servo system, three multiphase fault-tolerant mechanism schemes are proposed. Using finite element simulation, the performance parameters such as magnetic density, torque, torque ripple and motor loss in the normal state, one-phase open state and fault-tolerant state are comprehensively compared and analyzed, which is suitable for high reliability aerospace applications and optimal solution for multi-compatible motor.
