Analysis of Peak Torque, Peak Power, and Acceleration Time on Electric Motorcycles Conversion Using a V-Belt Power Transmit System.

Converting ICE (Internal Combustion Engine) motorcycles into electric motorcycles is one of the ways to accelerate vehicle electrification. The power capacity of the BLDC (Brushless Direct Current) motor used to drive this motorcycle is 2 kW. The power transfer system from the motor to the rear wheels uses a V-belt with a transmission ratio of 5,46: 1. The purpose of this research is to determine the amount of peak torque, peak power, and acceleration time produced by the motor. The method used to test the performance of the motor is using a dynamometer. The test results show that the peak torque produced by the motor is 23 Nm at 650 rpm, the peak power is 6 hp at 2480 rpm, and the acceleration time from 0 to 72 km/h is 9,58 seconds. The ICE of motorcycles produces a peak torque of 8,43 Nm and a peak power of 8,87 hp. Analysis based on test results shows that the BLDC motor 2 kW produces a peak torque 14,57 Nm above the ICE motorcycles but the peak power is 2 hp below the ICE motorcycles. These results indicate that the conversion of electric motorbikes is feasible to use.
