Abstract

In this paper, a novel view of a switched reluctance motor under dynamic eccentricity fault to provide the precise and reliable electromagnetics model is presented. It describes the performance characteristics and comparison results of the 6/4 switched reluctance motor with dynamic rotor eccentricity utilizing three-dimensional finite element analysis. The results obtained using three-dimensional finite element analysis of the switched reluctance motor includes flux-linkages, terminal inductance per phase, mutual inductances and static torque for various eccentric motor conditions. In this analysis the end effects and axial fringing fields for simulating reliable model are obtained and presented. The paper continues with comparing these results with the ones obtained for the same motor profile but utilizing two-dimensional finite element method. Finally, Fourier analysis is carried out to study the variations of torque harmonics.
