Performance Comparison of BLDC and SRM on Electric Motorcycle

This paper analyzes the comparison of two types of motors, namely Brushless DC (BLDC) and Switched Reluctance Motor (SRM) in the application of electric motorcycles. The development of electric vehicles is needed in the future, because of the pollution generated from conventional vehicles. At this time Brushless DC (BLDC) is popularly used as a motor drive of electric vehicles. However, BLDC requires permanent magnet material to generate torque, which is not cheap. Therefore, the Switched Reluctance Motor (SRM) was introduced as a new driving motor because it does not use permanent magnets. This study focuses on the comparison of the two motors in terms of torque, type flux distribution, flux density, heavy material, output power, RPM, and efficiency. Motor performance is calculated with the help of software along with a simulation model using the Finite Element Method. The simulation results show that the maximum torque that can be achieved by BLDC and SRM is 11.14 Nm and 10.1 Nm, respectively. Then, the results of the study also read that the weight of the material needed in the BLDC is 5.94 kg, lighter than the SRM which weighs 8.14 kg. Efficiency in BLDC is also known to be greater than SRM, which is 94.9% compared to 82.2%.
