Abstract On the basis of analyzing the principle structure of the dual-winding three-phase fault tolerant motor,this paper discusses the torque ripples and copper loss under motor open-circuit and short-circuit conditions.Then the doubling current fault-tolerant strategy,the optimal torque control,and the current vector fault-tolerant control are discussed in detail.The characteristics of these fault-tolerant control strategies are discussed and analyzed by calculation and simulation.Finally,the correctness of the proposed current vector fault-tolerant control is verified by the hardware experiment setup under healthy and open-circuit conditions.
