变频电机由于要承受高频磁场，所以绝缘等级要比普通电机高，原则上普通电机是不能用变频器来驱动的，但在实际中为了节约资金，在很多需要调速的场合都用普通电机代替变频电机，但普通电机的调速精度不高，在风机、水泵的节能改造中经常这样做。在用普通电机代替变频电机时变频器的载波频率尽量低一点，以减少高频对电机的绝缘损坏。变频电机加强了槽绝缘，一是绝缘材料加强，一是加大槽绝缘的厚度，以提高承受高频电压的水平。增大了电磁负荷。普通电机工作点基本在磁饱和拐点，如果用做变频，易饱和，产生较高的激磁电流，而变频电机在设计时增大了电磁负荷，使磁路不易饱和。另外就是变频电机一般分为恒转矩专用电机，用于有反馈矢量控制的带测速装置的专用电机以及中频电动机等。
以上就是变频电机和普通电机之间的区别，用户可以根据其特点，选择合适的电机。
