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 flnite element analysis. The results obtained using three-dimensional flnite element analysis of the switched reluctance motor includes ∞ux- linkages, terminal inductance per phase, mutual inductances and static torque for various eccentric motor conditions. In this analysis the end efiects and axial fringing flelds for simulating reliable model are obtained and presented. The paper continues with comparing these results with the ones obtained for the same motor proflle but utilizing two-dimensional flnite element method. Finally, Fourier analysis is carried out to study the variations of torque harmonics.
