논문제목:  Diagnostic Method for Non-Uniform Irreversible Demagnetization Fault Along z-Direction in PMSM Using Planar Search Coil

저자: Jun-Hyuk Im, Jun-Kyu Kang and Jin Hur, IEEE Fellow


Abstract— Since irreversible demagnetization fault can cause serious consequences in permanent magnet synchronous motors, various fault detection methods have been proposed. However, irreversible demagnetization fault may occur non-uniformly along the z-axis, and there is a possibility of misdiagnosis because the existing fault diagnosis method cannot determine the health of individual magnet layers. In this paper, a technique for diagnosing non-uniform irreversible demagnetization faults along the z-axis using planar search coils is presented
