SISTEM KENDALI ELEKTRONIK MOTOR BLDC PADA MOBIL LISTRIK

Abstract

The BLDC motor control system with practical speed control is designed to drive BLDC motors commonly used in electric vehicle systems. This system primarily functions to control the direction of motor rotation—both forward and reverse—and to regulate throttle input for speed control. The research focuses on utilizing an efficient and practical speed control mechanism, aiming to optimize motor responsiveness and collect experimental performance data. The Convenient Speed Control device operates as expected. It successfully controls the BLDC motor, allowing the vehicle to move forward and reverse, and enables manual throttle regulation. Voltage output while moving forward is higher than when in reverse. At full forward speed, the measured voltage reaches up to 38 volts, while in full reverse, it only reaches 21 volts. Additionally, testing at different speed levels showed a clear increase in phase voltage with higher speeds. At Speed 1, the average phase voltage is around 8 volts. At Speed 2, it increases to approximately 17 volts. Finally, at Speed 3, the highest voltage is recorded, with all phases averaging 21 volts. These results demonstrate that the controller responds proportionally to speed changes and performs well in regulating the motor under different driving conditions.
