The Switched Reluctance Machine (SRM) is a variable reluctance stepping machine designed to efficiently convert electrical energy into mechanical energy. The SRM was selected for this research because it has high efficiency and reliability. In addition, the machine is robust and cost effective. The SRM is an alternative to other types of machines for its applications, especially for starter generators. The SRM’s rotors do not generate significant heat, resulting in a simple cooling process. In addition, SRMs are known for their high reliability and ability to operate in four quadrants for a variable speed drive. Despite their great advantages, SRMs have not been widely used until recently because of their problems with torque ripples and noise. This research focuses on Finite Element Method Magnetics (FEMM) to model 12/10 SRM. The objective of this research is to generate static simulation results from the FEMM software and determine the flux-linkage and torque-current profile. Torque ripple results were compared with the previous topology (12/8 SRM). The torque ripple generated by 12/8 and 12/10 SRM is 7.57% and 6.02% respectively. Therefore, it can be concluded that the torque ripple generated by the 12/10 SRM is lower than that generated by 12/8 SRM. Based on these results, the 12/10 SRM can be used for starter-generator applications.
