摘　　要：将综合矢量法推广应用于多相永磁同步电动机电力推进系统缺相运行研究，提出了部分相绕组退出工作后剩余绕组不对称分布情况下产生圆形磁场的电流条件，给出了缺相情况下产生最大输出转矩的控制方法。仿真实验结果表明，该方法能够消除故障后转矩波动并产生最大可能的输出转矩。这一方法可使系统在故障状态下继续工作，对提高推进系统生命力有重要作用。By appliying synthetic vector method,the fault tolerance of a polyphase permanent magnet synchronous motor in subtrac- tion phase is analyzed for a electrical propulsion system.The current condition of producing a circular magnetic field is dis- cussed in the situation of asymmetric distribution of remanent windings after part of the windings out of working and a control strategy to get maximum gorque in condition of subtraction phase is given.The simulation results show that the proposed method can eliminate the torque fluctuation and get possible maximum ouput torque after failure of the system,so that the survivability can greatly be enhanced.
