Abstract
The switched reluctance motor(SRM) is widely used to the various fields of industry because of it's simple structure and synchronous operations. The main disadvantages of SRM are it's noises and vibrations during the operations which are caused by torque ripple. So, the main research of SRM in this thesis is focused on the reduction of the torque ripples. The conventional method to reduce the torque ripple is controlling the input current which needs the additional complex circuits inevitably.


In this thesis, the shapes of the SRM rotor are designed to reduce the torque ripples. The finite element methods are used to design the shapes of the rotor. The method to develop the rotor shape to reduce the torque ripples are presented and the effects of the rotor shapes along with driving currents are analysed.
