Implementation and verification of the PMSM stator interturn short fault detection algorithm

This paper discusses the stator winding interturn short fault detection for three phase Permanent Magnet Synchronous Machines (PMSMs). The implementation of the Extended Kalman filter (EKF)-based fault detection algorithm is discussed. The implemented algorithm was verified with the emulated fault during different operating conditions of the drive. Measurements on a real PMSM and the implementation verification are the most important objectives of the article.
