6 Rotor Optimization of Double Stator Switched Reluctance Motor for Torque Ripple Reduction and Increase in the Average Torque Mohammadali Tavakkoli m tavakkoli@ec iut ac ir Department of Electrical and Computer Engineering Isfahan University of Technology Isfahan 84156 83111 IranSupervisor Mehdi Moallem moallem@cc iut ac irAdvisor Behzad Mirzaeian mirzaeiani@eng ui ac irAbstract In This dissertation an effective rotor shape optimization for torque ripple reduction of the Double StatorSwitched Reluctance Motor DSSRM is presented This method leads to a lower torque pulsation as well assignificant increase in the average torque The method is based on the shape optimization of the rotor usingFinite Element Method FEM Rotor reshaping is based on redistribution of the flux so that the phaseinductance profile has a smoother variation as the rotor poles move into alignment with the excited statorpoles Steady state analysis is conducted to evaluate effects of the new rotor shape Finally to check on therobustness of the new design 3 D FE mechanical analysis is used to evaluate structural resistance againstlocal electromagnetic forces The results show that this shape optimization technique introduces a profoundimpact on the torque ripple reduction and at the same time increases the average torque Keywords Double Stator Switched Reluctance Motor Finite Element Method Mechanical Stress Analysis TorqueRipple ReductionIntroduction The Switched Reluctance Motor SRM has unique capabilities of operation at highspeeds and in harsh environments Therefore they are good candidates for industrial andautomotive applications Due to the absence of the excitation winding or permanentmagnet on the rotor they are not susceptible to rotor winding faults and demagnetizationor centrifugal detachment of the magnets Furthermore owing to its stiff structure and theabsence of the magnetic source on the rotor an SRM is inherently rugged and inexpensive
