Analysis of The Influence of Loading Variations Toward Brushless Direct Current Motor Performance on KARLING Electric Vehicle

Abstract

One type of electrical motors often used for electric vehicle purposes is Brushless Direct Current Motor (BLDC Motor). BLDC motor performance can be seen from its current line, electromagnetic torque, rotational speed, induction voltage, and input power as the parameters. The research’s aim is to find out the effect of loading towards BLDC motor performance on the electric vehicle. The loading variations are used in the form of passenger weight and track characteristics variations. The variation of passengers’ weight is 55 kg, 78 kg, and 143 kg. In this study obtained line current value when the passengers load 143 kg is 41.52 A. Furthermore, the values of the electromagnetic torque and energy consumption in the same weight are 23.88 Nm and 0.06 kWh/km. To ascertain the effect of track characteristics variations to the motor parameter, variations of track characteristics are done in trajectory 0° and 1.25°. The outcome is the 1.25° tilted track has higher energy consumption but lower speed.
