Performance investigation on segmented rotor switched reluctance motor

Abstract

Among a host of design topologies, the segmented rotor switched newlinereluctance motor has evolved as a promising contender to research for variable newlinespeed applications. The thesis orients to evaluate the performance of the newlinesegmented rotor switched reluctance motor and draw a comparative study with newlineconventional SRM to indicate the effectiveness of the 6/5 segmented SRM newlineconfiguration in terms of average torque. The results highlight the need for newlinereducing the torque ripple and improving the efficiency. newlineThe influence of laminating materials like CR10, M19, M800-65A, newlineM43 and M890-50D on the performance of segmented rotor SRM has been newlineanalyzed and the results indicate the material M890-50D exhibits better newlineperformance in terms of improved efficiency. newlineThe effect of modified rotor segments structures, tapered stator pole, newlinerotor pole depth and stator pole arc on the performance of 6/5 segmented rotor newlineSRM is analyzed. A novel structure incorporating the finest modifications is newlineproposed to minimize the torque ripple. Based on the analysis this thesis puts newlineforth a proposal for a modified pole configuration to reduce torque ripple. newlineThe analysis carried out with respect to laminating material and pole newlineshape modification has been intended to improve electromagnetic behaviour. newlineHowever, the impact of these modifications on the structural characteristics newlineneeds to be addressed and in this prelude this thesis engages the use of ANSYS newlinesoftware to investigate the vibration characteristics of the motor. newlineThe thermal characteristics of the motor gains significance in terms newlineof determining the temperature rise and cooling requirements newline
