摘要：
The paper proposes a fault-tolerant control strategy for a two-phase permanent magnet synchronous motor (PMSM) by a structural alteration. Firstly, a two-phase PMSM is designed with a structure of combination with two conventional single-phase U-core PMSMs. Each has a self-start ability because of the step air gap design on the inner side of stator, and two sets of magnet in the motor are placed as 90 electrical angle shift. If one is fault, the other can work continually. Secondly, a drive with the space vector modulation (SVM) technique is designed for the proposed system. Considering the possible faults, a fault-tolerant technique is proposed to improve the system robustness. The experimental results show the validity of the proposed system.
