IC693MDL634RR 很多人已经发现了变频器对电机损伤的现象。例如，某水泵厂，近两年来，他的用户频繁报告水泵在保修期内发生损坏的现象。而过去，这个水泵厂的产品质量十分可靠。经过调查，发现这些损坏的水泵都是用变频器驱动的。

尽管变频器损伤电机的现象越来越被人们所关注，但是人们对造成这种现象的机理还不清楚，更不知道如何来预防。本文的目的是解决这些困惑。

变频器对电机的损伤

变频器对电机的损伤包括两个方面，定子绕组的损伤和轴承的损伤，如图1所示。这种损伤一般发生在几周至十几个月内，具体时间与变频器的品牌、电机的品牌、电机的功率、变频器的载波频率、变频器与电机之间的电缆长度、环境温度等诸多因素有关。电机的早期意外损坏给企业的生产带来巨大的经济损失。这种损失不仅是电机维修和更换带来的费用，更主要的是意外停产带来的经济损失。因此，在使用变频器驱动电机时，对电机损伤的问题有足够的重视。
