Finite Element Analysis of Switched Reluctance Motor under Dynamic Eccentricity Fault

This paper describes the results of a two-dimensional finite element analysis carried out on an 8/6 switched reluctance motor for studying the effects of dynamic eccentricity on the static characteristics of the motor. Flux contours, flux-linkage profiles and mutual fluxes are obtained for both healthy and faulty motor. Besides, Static torque profiles of phases are obtained for different degrees of eccentricity and it is shown that at low current; the effect of eccentricity is considerable compared to that of the rated current case. Finally, Fourier analysis of the torque profiles is performed to make their difference visible.
