Abstract :
In this paper, a new technique for on-line detecting inter-turn stator winding fault in Permanent Magnet Synchronous Machine (PMSM) is presented. It is based on a residual analysis improved by adding a back-EMF waveform estimation system which allows identifying real back-EMF frequency components of the healthy machine. Then, a simple current residual monitoring permits us to detect the fault and its severity. Simulations and experimentations validate the proposed method and its efficiency.
