In this paper, the computer aided design, analysis, optimization and manufacturing processes of switched reluctance machine (SRM) with a piece of self-developed software are detailed presented. According to the performance requirements, the physical dimensions of stator and rotor laminations are obtained by two traditional methods. Then, the electromagnetic characteristics and operating performances of the designed SRM are calculated by magnetic equivalent circuit (MEC), and optimization algorithms, such as genetic algorithm (GA), are applied to enhance certain performance indexes. Finally, for convenience of manufacturing, the machining drawings of the designed SRM are generated as well.
