Stepper Motors
Two Phase Stepper Motors
The Stepper motor is a special motor specially designed for accurate control of position and speed. the biggest characteristics of stepper motor is 'digital'. For each pulse signal from the controller, the stepper motor driven by its drive runs at a fixed angle('one step for short').
