Abstract

Electric vehicle manufacturers have a significant need for brushless DC (BLDC) motors. This is because of its benefits, including brushless construction, high efficiency and power ratio, huge mass, and ease of control. This study aims to examine the relative importance of the various variables on the three motorcycles that the three prototypes are actually mounted on. In order to optimize the technical testing process and save wasteful time and expense, the Taguchi Method with the characteristic of smaller is better was employed for the research. Two different types of road terrain were used for the tests: flat and uphill with slope angles of 2 and 4. Use. Prototypes 1, 2, and 3 of the electric motors utilized in this study each feature a distinct ratio of magnetic poles: prototype 1 has 48 poles/54 slots, prototypes 2 has 50 poles/45 slots, and prototype 3 has 40 poles/36 slots. According to the test results, the type of electric motor, the type of road, the distance, and ultimately the speed level are the parameters that have the greatest influence.

Abstract

The reduction of carbon dioxide emissions, or decarbonization, across all sectors must be carried out seriously. One of these sectors is transportation, through the implementation of an electric vehicle (EV) ecosystem by converting fossil-fuel-powered motorcycles into electric motorcycles. This study aims to design and analyze the performance of a 2 kW mid-drive BLDC motor in an electric motorcycle conversion application. The transition to electric vehicles requires conversion components, such as a BLDC motor. A collaborative research project with an industrial partner, PT X, focuses on the design and modification of a 2 kW mid-drive type BLDC motor. The design process was carried out by varying the gear ratios of 0.68, 0.72, and 1.34 to obtain an electric motorcycle conversion speed suitable for urban road use. Dynotest results indicate that the gear ratio variation of 0.68 provides the best performance using 30T and 20T gears. The maximum speed achieved under this configuration was 78.8 km/h, with a torque of 24.18 Nm at 987 rpm and an output power of 2.8 kW at 1526 rpm.
