Abstract :
An opening of a stator phases in the multiphase induction machines leads to a torque oscillations and rotor speed ripples. In this paper, a stator current spectrum (called Motor Current Signature Analysis MCSA) is used to detect an open stator phase. The induction machine has a dual three phase windings spatially shifted by sixty electrical degree. The aim of the proposed approach consists in computing the rotor speed ripple of the SPIM under open phase.
