Switched Reluctance Motor (SRM) is a motor without a magnet so it has a strong structure, is able to operate at high temperatures, and has a low price. The low cost of SRM construction makes this motorbike potential to be developed in Indonesia. This research shows the design and optimization of 12/8-5 kW, for light vehicle applications. In the first study, the design was carried out using the iteration method or DoE (design of experiment) in the next stage, optimization with a single objective was investigated and in the third stage, this study proposed a multiple-objective genetic algorithm optimization method with the objectives of minimum core loss and maximum output torque, four main variables by pre-designed calculations as individuals in the initial population. The motor parameters are stator outer diameter, air gap, rotor inner diameter, motor length, shaft diameter, stator, and rotor pole height, these seven parameters are fixed. While the optimized variables are rotor pole tip width ????????????, rotor pole bottom width ????????????, stator pole width ???????? , rotor bottom diameter ????????????. These four variables will not affect the dimensions of the motor frame, so that it will facilitate the revision of the production process. This method is implemented for a 5 kW SRM. This motor is modeled by the finite element method and coupled with an excitation circuit. The process of modeling, simulating and manufacturing the motor has been carried out. The optimization results obtained SRM no. 5, which is the optimum motor with the characteristics of increasing the output torque by 13.32% and reducing the core losses by 11.56%. This method shows that the optimization stage has succeeded in reducing core losses and increasing the SRM output torque.
