Stepper motor driver usually consists of pulse generator, power module, signal decoder, driving module and so on.
When the stepper motor driver receives a pulse signal, it will drive the stepper motor to rotate by a fixed angle or stepping angle in the set direction to complete a series of continuous moving or positioning operations.
By controlling the number and frequency of pulses, the rotation angle and speed of stepping motor can be controlled, and the purpose of accurate positioning and speed regulation can be realized.
