永磁同步电机传动系统在电动车辆上的应用

Application of PMSM Drive System for Electric Vehicle

介绍了永磁电机的特点、发展现况及其在轨道车辆和电动汽车中的应用。永磁电机的转子损耗很小、功率密度高,可采用多极,为采用直接驱动、全封闭结构和系统集成化提供了可能。永磁电机传动系统在轨道车辆上的应用已进入实用阶段,在电动汽车上已向商业化量产方向进展。

It introduces the characteristics of permanent magnet motor, presents its development status quo and applications in railway vehicle and electric bus/car. Permanent magnet motor has less rotor loss, high power density, and can use multi-pole. All these make it possible to the system with direct driving, full-closed structure and system integration. Permanent magnet motor drive system for railway is now in the applied period, and the system for electric bus/car is toward to business mass production.
