Abstract: This paper presents a study of PMSM under short circuit in turns at different speed and torque values.PMSM in a healthy state and under fault conditions is simulated at different working points using a Flux 2D, twodimensional(2-D) finite element analysis (FEA). Currents and flux density are presented and their harmonic content is obtained. In addition, harmonics content is compared to one obtained from a healthy motor. This paper applies the appropriate tools for determining the fault condition from the current analysis as Empirical mode decomposition (EMD) with Wigner Ville Distribution (WVD). The EMD and WVD are used to fault detection in the operation range of PMSM. Simulated and experimental stator current spectra from healthy and faulty
machines are obtained and compared.
