一种基于电压畸变的永磁同步电机匝间短路故障鲁棒检测与定位方法

In this article, a voltage-distortion-based method is presented for robust detection and location of interturn fault (ITF) in permanent magnet synchronous machine (PMSM). The mathematical models of PMSM under healthy and fault conditions are presented. According to the mathematical model, the dq-axis voltage distortions owing to ITF are estimated through Luenberger observer. On the basis of the vo...
