ST7FMC in the BLDC Motor Controller

The high-performance,highly integrated and PWM signal providing MCU ST7FMC is used in oil field screw pump DC motor speed control system which adopts ST's brushless DC motor control ideas to make the brushless DC motor as the power equipment of the screw pump oil production system.This method has advantages of high efficiency,low noise,big starting torque and good speed adjusting performance.The principle of brushless DC motor controller and the implementation of brushless DC motor controller with sensor are introduced in this paper.
