A finite-element model for induction machines incorporating winding faults

The paper shows how finite element model may be used to simulate the effect of short circuit fault in the stator winding of multiphase cage induction machine [1–4]. The proposed analysis is carried out for incident faults and the 3-phase winding currents are investigated. Since the stator winding short circuit faults are one of the most common and potentially destructive electrical faults in induction motors a short circuit in one coil is considered in this study. The Flux 2D numerical model is validated against experimental results and analytical simulations in PC-IMD [2].
