Design And Implementation of Three Phase Motor Driver For PWM-Based BLDC Motor Speed Control

Abstract

The Along with the times, the need for motors that have high efficiency, high torque, high and variable speed, and low maintenance costs has increased. one of these motors is a Brushless DC motor that uses electric commutation so that it has high efficiency and long operating time. Therefore, to meet the need for high efficiency, high torque, high and variable speed, and low maintenance costs, a Brushless DC motor (BLDC) or a Brushless AC motor (BLAC) is used. BLDC motors are widely used in industry compared to other types of motors, because BLDC motors have many advantages. But there is also a weakness of the BLDC motor, namely the difficulty in regulating the speed. With this condition the author is interested in making an innovation to overcome this problem, by making a three-phase motor driver as a BLDC motor control to regulate the rotation of the BLDC motor so that the speed can be varied. This three-phase motor driver consists of an Arduino Nano microcontroller and a three-phase inverter circuit that uses an IRF3205 MOSFET. The Arduino Nano microcontroller is used as a MOSFET ignition in a three-phase inverter circuit, the result is The success parameter of this research is being able to determine the commutation of the BLDC motor which is then controlled by a three-phase inverter through the Arduino NANO microcontroller to control the speed of the BLDC motor with a certain frequency.
