Abstract

In this paper, a new technique of on-line detection of inter-turn short circuits in stator of permanent magnet synchronous motor (PMSM) is proposed. The study is focused on a PMSM with non sinusoidal electromotive force (emf). The technique is formulated by combining extended Parkpsilas vector approach and classical recursive least squares algorithm (RLS). The faults are detected by analysing the abnormal variation of electrical estimated parameters of the 2-phases model in the Extended Park frame.
