The role of the motor driver: the role of the motor driver refers to the control of the duty cycle to achieve idle control of the motor by controlling the rotation Angle and running speed of the motor. Why a motor needs a driver: Whether it is a brushless DC motor, a stepper motor, or a servo motor, it will be paired with the corresponding driver. 1, the DC brushless motor replaces the mechanical commutator with an electronic commutator, and the DC brushless motor needs to use the driver drive circuit because of the electronic commutation. 2, the stepper motor to run then must input pulse, if there is no pulse, the stepper motor is not moving, so we need a driver to the winding of the stepper motor in turn energized. 3, the servo motor is no brush and commutator, so to maintain the rotation direction, it is necessary to have an electronic commutator. The electronic commutator is controlled by the driver, and the servo controller can also control the start and stop of the motor, positive and negative rotation, speed adjustment, over-voltage, over-current and under-voltage protection. Therefore, there must be a servo drive, even if the servo motor is directly powered on, it will not work. Therefore, different drivers have different functions, and what they have in common is to control the motor more accurately.
