当电机线圈阻值三相平衡时，也不能说电机就是好的，还要测量电机的绝缘电阻，一般电机绝缘电阻低于0.58MΩ时，说明电机绝缘不好，不宜使用。电机绝缘电阻高于0.58MΩ时，说明电机绝缘性好，可以正常使用。

用万用表测量电机时，万用表档位在电阻MΩ档。一只表笔搭在U1、V1、W1任意端子上，另一只表笔搭在电机外壳上，注意要搭在没有油漆的地方，测量的的阻值大于0.58MΩ或者不通时，可以判断电机绝缘正常。测量的阻值小于0.58MΩ时，绝缘不好，不宜使用。万用表测电机的绝缘电阻不准确，当感觉每次测量电机绝缘电阻值都不一样时，影响了你的判断。可以使用兆欧表，万用表测量的数据只具有参考价值，而兆欧表测量的数值准确性比较高，可以当成真实数据。

兆欧表的E、L接线柱，接入测线棒，两个测线棒的测量方式与万用表表笔测量电机方式相同，兆欧表没有档位调节，只要以每分钟120转摇动手摇杆即可。
