DOUBLE AND SINGLE LAYERS FLUX-SWITCHING PERMANENT MAGNET MOTORS: FAULT TOLERANT MODEL FOR CRITICAL APPLICATIONS

This paper deals a double layer and a single layer Flux-Switching Permanent Magnet (FSPM) motors for a fault tolerant application. The self and mutual inductances of these two machines are calculated, which are then applied for establishing a faulty model. A three phase short-circuit problem is simulated for these two motors. A comparison between these two machines is carried out, which is in terms of normal phase currents and the output torque before and after the failure as well as the short-circuit peak currents against the rotor velocity
