ABSTRACT
In this study, the mitigation of torque ripples at mutually coupled switched reluctance motor (MCSRM) is investigated experimentally. Although, MCSRMs have higher performance than classical switched reluctance machines (SRMs), they are not attractive enough due to their high torque ripples. There are many different methods to solve this problem. One of the methods is to change the geometric structure of the machine. The analyses of previous studies show that despite there being favorable results in applications, the molding pins of the machines are neglected in those works. A motor that gives positive results may get affected negatively by its random molding during generation. In this research, a 3-phase average 100 watt MCSRM is chosen for analysis and effects on torque of the geometric point of molding pins in the machine are studied comparatively. Maxwell 2D program is used for analyses and two different models are compared with each other. The obtained results show that torque ripple of the machine is lower when molding pins are closer to the rotor post, and it is reduced by 12% at 6 Amps in the proposed MCSRM.
