摘　　要：为了提高交流电机绕组故障判断的准确性,本文对交流电机绕组直流电阻测试的有效性进行了分析,并提出了测试电机工频特性值的做法。建议在测试电机直阻的基础上,加测电机绕阻的电感,阻抗,相角等工频特性值,综合分析各种数据,这样能快速准确地找出电机绕组方面的故障。To improve the accuracy of judging the motor＇s fault, this paper analyzes the availability of DC resistance measurement for AC motor, and offers some proposals such as measuring the AC characteristic values of inductance, impedance, phase angle etc based on DC resistance, and comprehensively analyzes these testing data. Then we can find and confirm the fault of motor＇s winding accurately.
