Dynamic eccentricity fault diagnosis in switched reluctance motor

In this paper, a novel view of switched reluctance motor analysis under eccentricity fault for providing the precise and reliable model is presented. It then continues with describing the performance characteristics and comparison results of a six by four switched reluctance motor with dynamic rotor eccentricity utilizing three-dimensional finite element analysis. The results of the three-dimensional finite element analysis for a switched reluctance motor including flux-linkages, terminal inductance per phase, and mutual inductances for various eccentric motor conditions by considering the end effects and axial fringing fields for simulating reliable model are obtained and presented. Finally, these results present useful information regarding to the detection of dynamic eccentricity.
