摘　　要：随着永磁电机的发展,越来越多的人相信并选择具有高效率且节能效果显著的永磁电机,在节能改造时优先选择永磁机替换同规格异步机,但在替换过程中,受到很多条件限制,比如空间限制、老旧的变频器等,这种条件下,对永磁机的要求就更为苛刻。文中介绍的就是一种可以变频调速的同时又可以空载自起动的永磁三相同步电动机,并结合分析软件,了解永磁机的特点。With the development of permanent-magnet motor,more and more people believe and choose the permanent-magnet motor with high efficiency and remarkable energy-saving effect.In the energy-saving transformation,the permanent-magnet motor is preferentially adopted to replace asynchronous machine with the same specification.However,it is limited by many conditions in the process of replacement such as space limitation and old frequency converter.Under these conditions,the requirements for permanent-magnet motor are more stringent.This paper introduces a kind of three-phase PMSM,which not only can carry out frequency conversion and speed regulation but also can no-load self starting.Combining with analysis software,the characteristics of the PMSM is understood.
