Based on the analysis of the mechanism of exploring coil detecting turn-to-turn short circuit of rotor winding, fault diagnosis system is designed. Based on WTMM, the signal is analyzed and the Lipschitz index of wave characteristics is calculated. With MATLAB as the background to simulate the signals and the variance of Lipschitz index as calibration, the fault location and degree of the turn-to-turn short circuit can be determined. The experiment shows that determining the fault and the fault degree by means of Lipschitz index is reliable and easy.%分析了探测线圈检测电机转子绕组匝间短路故障的机理,构建故障诊断系统.以WTMM为基础,对信号进行分析并计算波峰特征的Lipschitz指数.以MATLAB为后台对信号进行仿真,以Lipschitz指数α的方差为定标,得出发生匝间短路故障的位置和故障程度.实验表明,通过Lipschitz指数来判断故障发生及其故障程度是一种可靠易行的办法.
