Aiming at the torque ripple caused by the departure of emf from idle waveform, an in-depth research on the optimizing design technique of emf from the aspects of winding design, eccentric air-gap design and rotor magnetic circuit structure design.

• 针对电机反电势偏离理想波形造成转矩脉动的问题,本文从电机本体设计出发在绕组设计,转子偏心气隙设计及转子磁路结构优化等三个方面对反电势正弦化设计方法进行了深入研究。
