    2 Phase Digital Stepper Motor Driver 18v~36v Details

    Tips: Functions of stepper motor driver

    The digital stepper motor driver is an actuator that converts electrical pulses into angular displacement. In the use of the motor, the driver receives a pulse signal, and drives the motor to rotate a fixed angle in the set direction, and rotate step by step at a fixed angle. The stepper motor driver can control the angular displacement by controlling the number of pulses, and can also control the speed and acceleration of the motor's rotation by controlling the pulse frequency. Through these two methods, the positioning control and speed control are realized respectively. The entire stepper motor drive system is composed of two parts: a motor and a driver. While the performance of the drive system depends on the performance of the motor itself, it also depends on the pros and cons of the drive stage.

    Existing reviews of Digital Stepper Motor Driver, 2 Phase, DC 18V ~ 36V
    Works perfectly.
    This is in my opinion a good value for the money. Exactly what I needed. Arrived quickly and efficiently! I wanted to drive a Nema 17 2 phase stepper motor stepper with my 3D printer, this made that possible. It exhibited good accuracy.
