摘　　要：容错型电机驱动系统成为国内外学者的研究热点。提出了8/6极电励磁双凸极电机(WFDSM)单相开路容错型拓扑结构,借助有限元电磁场分析技术,在分析电磁转矩的产生机理基础上,对此拓扑结构的控制策略以及电机在正常运行、单相开路及单相开路容错这三种不同工作状态下的运行特性进行了分析研究。仿真结果表明,此拓扑结构可以有效地降低故障对电机运行产生的影响,验证了该拓扑结构的有效性。It is known that fault-tolerant driving system has been of great interest for the motor drive community and marketplace. A new fault tolerant drive topology for an 8/6-pole wound-field double salient motor（WFDSM） was proposed. Based on the analysis of mechanism and properties of electromagnetic torques production, operation characteristics of the proposed topology under various conditions were simulated, including normal condition, single phase open circuit fault condition and single phase open circuit fault tolerant condition with the help of finite element analysis. The proposed topology was validated by simulation which showed that the proposed topology could effectively reduce the influence of open circuit fault on the electromagnetic performance of the motor.
