Impact of Yoke Thickness variations on Operating Performance of Switched Reluctance Motors: Quantitative Analysis

Environmental concerns, notably greenhouse gas emissions and global warming, underscore the urgent need for sustainable transportation alternatives. Among the various motor types, Switched Reluctance Motors (SRMs) have emerged as promising candidates for powering these small-scale electric vehicles. Their wide constant power range, and favorable torque-speed characteristics make them well-suited for applications such as EV. To ensure optimal SRM performance, a meticulous design process is crucial. In this study, our investigation focuses on analyzing the effects of changing the pole geometry of the stator and rotor yoke thickness, ranging from 5 mm to 10 mm. By employing ANSYS Finite Element Analysis (FEA) simulations, our research aims to identify the optimal yoke thickness that enhances motor efficiency, power output, torque, flux linkage and flux density. Our findings reveal that specific combinations of stator and rotor yoke thickness significantly influence SRM performance. Notably, we achieve a peak efficiency of $63.777 \%$, a maximum power output of 555.22 W, and a torque of 7.23 Nm. These insights provide valuable guidance for designing and optimizing SRMs in electric vehicle applications, ultimately contributing to improved performance and energy efficiency.
