Design of the 3 kW Electric Motorcycle

This paper presents an electric motor design by using a 3kW multiphase brushless direct current (BLDC). The research found that initial motor capacity is not easy to obtain because torque is affected by mechanic and passenger masses, and the rotation per minute (rpm) is affected by the gear arrangement. By using two gear arrangements, 48V 25AH battery source, and a commercial mechanical frame; the implementation results is 35km/h speed where the motorcycle only requires 0.3kW to travels for distance about 4.1km. The cost is much lower than the petrol based motor.
