Modeling of Inter-Turn and Inter-Phase Short-Circuit of Flux-Switching Permanent Magnet Motors

This paper presents an approach for detailed modelling of inter-turn and inter-phase short-circuit in a double layer, 12-slot and 10-pole Flux-Switching Permanent Magnet motor. This approach is based on MATLAB/Simulink and finite element analysis, and shows a fast and accurate estimation of the electromagnetic behavior for such machine under short-circuit conditions. Due to physical contact between different phase windings in the same stator slot, the inter-turn and inter-phase short-circuit in a double layer FSPM machine becomes a real possibility. However, this is rarely studied in the literature. Thus, this work contributes for the fault analysis of inter-turn and interphase short-circuit problems. Experimental tests have been carried out to validate the simulations.
