摘要
针对工业驱动电机轴承放电加工(EDM)电流研究成果对电动汽车(EV)驱动电机并不完全适用的问题,基于电动汽车的电机驱动系统,分析了驱动电机EDM电流的产生机理,总结了当前工业脉宽调制(PWM)驱动电机EDM电路问题的研究进展,并对其主要成果进行评述,基于电动汽车独立电源的形式和行驶特性,讨论了驱动电机轴承EDM电流的特殊性,最后,给出了电动汽车驱动电机EDM电流研究中应重点关注的方向,可为电动汽车驱动电机轴承EDM电流问题的研究提供参考。
According to the research results of bearing EDM (electrical discharge machining)current on industrial drive motor is not fully applicable to EV(electrical vehicle)motor,based on the special driving structure of EVs,analyzed the bearing EDM current generation mechanism of EVs drive motor,summarized the research progress of industrial drive motor EDM current,and commented the main achievements.Aiming at the independent source and running conditions of EVs,discussed the particularity in EDM current of EVs drive motor.At last,the key directions of bearing EDM current in EV drive motor was given which could be the reference in future.
