摘要
研究了一种分数槽集中绕组低谐波永磁同步电机,介绍了该电机特殊的绕组结构,分析了电机在正常运行时降低磁动势谐波的原理,并提出了电机在开路故障时相应的容错控制策略,即以输出平滑转矩和仍具有降低磁动势谐波效应为约束进行容错控制。最后,通过仿真和实验验证了所提出的容错控制策略的有效性。
A fractional slot concentrated winding low harmonic permanent magnet motor isinvestigated in this paper.The special winding structure of the motor is presented and the principle ofreducing the MMF harmonic at the normal operation is analyzed.And a fault-tolerance control strategyis proposed for the motor under the open circuit fault,in which smooth output torque and lowerharmonic effect are used as constraint conditions.Finally,simulation and experiments verify theeffectiveness of the proposed fault-tolerant control strategy.
