Rotor fault analysis and diagnosis in three-phase outer-rotor switched reluctance motor

In this paper, a three-phase outer-rotor switched reluctance motor (ORSRM) is introduced and analyzed. This paper then continues with modeling this motor in the static mode for healthy condition as well as motor with dynamic rotor eccentricity utilizing three-dimensional finite element analysis (3-D FEA). The results of the numerical analysis for a 6 by 8 ORSRM including flux distribution, flux linkages and radial force for various eccentric motor conditions are obtained and compared and detection method is presented. The obtained results demonstrate useful information as good candidates for fault evaluation as well as the amount of eccentricity fault and the direction of fault occurrence.
