Driving a 3-phase brushless DC motor is very easy with this project. It is a simple and easy-to-build project that requires only a few external components. The circuit is based on AMT49400 IC which is an advanced 3-phase, Sensorless, brushless DC (BLDC) motor driver with integrated power MOSFETs. The chip includes the field-oriented control (FOC) algorithm which is fully integrated to achieve the best efficiency and acoustic noise performance. The motor speed is controlled by applying a duty cycle signal to the PWM input. Users may use Arduino, microcontroller, or discrete circuit to generate PWM for the speed controller. It is a hassle-free easy to use board, just connect the 3 phase brushless motor, connect the power supply and feed PWM to control the speed of the motor. This project is the best choice to drive a FAN motor, small pumps, and brushless toy motors, etc.
