摘　　要：为能更好地判定异步电动机出现断条故障的严重程度,根据灰色系统理论,计算电动机三相定子电流与完好电动机的灰色关联度,可确定电动机断条故障的严重程度,再通过测量完好电动机、一根断条电动机、三根断条电动机的三相定子电流,得到原始实验数据,最终按计算结果来判定异步电动机处于断条故障的严重程度。灰色关联度理论按现有的矢量方法相比较,验证了该方法的可行性。In order to be better able to determine broken fault severity of the asynchronous motor, according to thegray system theory, calculates the motor three-phase stator current with intact motor gray relational grade, which in order to determine the severity of the motor broken fault failure. By measuring the intact motor, a broken motor,three broken bars motor three-phase stator current, get the original experimental data. The calculation indicates the asynchronous motor is in the seriousness of the failure. And the faults can be determined by gray relational analysisfauhy motor quickly, and compared with the existing mature theory, to verify the accuracy and feasibility of this method.
