Abstract :
Interturn stator winding fault is one of the most frequent faults in permanent-magnet synchronous machines (PMSMs). In this paper, we present a new technique for online detection of this fault in PMSMs. It is based on a residual analysis improved by taking into account back-electromotive force waveform estimation, inverter model, and unbalanced inductance matrix. Then, a current residual monitoring block permits to detect the fault and its severity. The simulation and experimental results validate the proposed method and its efficiency.
