摘　　要：对双三相永磁同步电动机发生一相短路故障时的磁场分布、磁链、电流以及输出转矩等电磁性能进行分析,并与传统三相电机进行比较.结果表明,双三相电机相与相之间的耦合较弱,故障相几乎不影响非故障相的正常运行,电机依然能够在可接受的范围内继续工作,具有一定的容错能力,适用于对电机连续运行有特殊要求的场合.The electromagnetic performance of the electromagnetic field distribution, flux linkage, current, and output torque and so on are analyzed, when dual three-phase motor is in fault condition of short-circuit of one phase winding. At the same time, it is compared with traditional three-phase motor. Results indicate that coupling between phases of dual three-phase motor is very weak. In fault condition, the fault phase of dual three-phase motor dose not affect normal operation of non-fauh phase which makes it can still continue to work within the acceptable range. So dual three-phase motor does not have to stop on the way, and has a certain tol- erance, and is applicable to the occasion which has special requirements for motor.
