1. The stepper motor must operate with driver. The drive signal must be a pulse signal. When there is no pulse, the stepper motor is stationary. If an appropriate pulse signal is added, it will rotate at a certain angle (called the step angle). The speed of rotation is proportional to the frequency of the pulse.


2. The stepper motor has the superior characteristics of instant start and rapid stop.


3, Change the order of the pulse, you can easily change the direction of rotation.
