Abstract: This paper attempts to analyse the characteristics of the inter-turn short circuit fault for the permanent magnet synchronous motor (PMSM). Based on finite element analysis (FEA), the influence of the stator faults on the behaviour of the PM machine is studied. A simple dynamic model for a PM machine with inter-turn winding fault is presented. The precision of the proposed finite element (FE) model is verified by a comparison of the simulation results tests. Using the simulated model, a technical method, based on fast fourier transform (FFT) analysis of stator current and electromagnetic torque, is exported to detect the inter turn fault. The technique used and the obtained results show clearly the possibility of extracting signatures to detect and locate faults.

Keywords: finite element method; FEM; permanent magnet synchronous motor; PMSM; winding short-circuit; fast fourier transform; FFT; analysis.
