稀土永磁同步电动机的起动特性

On starting character of rare-earthpermanent magnetic synchronism motor

通过对稀土永磁同步电动机起动性能的研究,分析了牵入转矩与起动转矩二者的相互矛盾性,提出了改善其起动性能的办法,并指出了不同的转子结构对起动性能的影响.

By studying the starting character of rare-earth permanent magnetic synchronism motor,this article analyses the contradictions between pull-in torque and start torque,provides the way of improving starting performance of motor,and indicates the effects of different rotor runner structures to the capacity of starting.
