本文针对一种具有144°平顶梯形波的五相容错永磁无刷直流（BLDC）电机提出了基于转矩等效的容错控制策略。在保证输出转矩相等的基础上，推导了故障条件下的BLDC电机容错式BLAC控制策略。仿真和试验结果表明，该容错控制策略可以保证五相DLDC电机在故障条件下保持正常运行时的转矩性能。

In this paper , a new fault-tolerant control strategy was proposed for remedial operation of a five-phase permanent-magnet brushless DC (BLDC) motor, which had 144°trapsoidal back-EMF.In order to maintain the average torque under normal condition , a remedial brushless AC ( BLAC) mode was proposed for this faulty BLDC motor.Both simulation and experimental results were given , verifying that the new con-trol strategy can enhance the torque performance of faulty operation.
