THE VARIABLES IN TORQUE AVERAGE AND TORQUE RIPPLE BY STATOR/ ROTOR POLE ANGLE AND MATERIAL OF SWITCHED RELUCTANCE MOTOR

Abstract

This paper will analyze influence of stator, rotor embrace and on average torque of SRM. The Switched reluctance motor of three phase 6/4 and 12/8 with magnetic steel material M270_35A and M19_24G has been selected to build model. The 2D SRM simulation of 6/4 and 12/8 was implement by Anasys Maxwell.The stator and rotor pole angle of three phase 6/4 and 12/8 can be changed by rotor and stator embrace. The results were shown that the changes of material are not so move to position of point maximum of average torque, only changes the amplitude of the torque characteristic. The stator pole angle and rotor pole angle parameters have significant on average torque and efficiency. Maximum torque will be achieved at stator embrace ratio of 0.5 and maximum average torque is maximum at 0.3 with SRM 6/4 and 0.4 with SRM 12/8.
