Brushless DC Motor Driver based on SA306A Integrated Switching Amplifier

Brushless DC motor is widely used in the field of industrial control because of its low price and excellent performance. In this paper, the hardware system of the brushless DC driver is designed. In this driver, SA306A three-phase intelligent switching amplifier is used as the power drive module, and STM32F103VET6 is used as the controller. The provided scheme of printed circuit board integrates the motor control, current monitoring, temperature monitoring, speed feedback, communication, and other modules. The safety and reliability of the system are verified by practice, and the results are in line with the expectations.
