Stepper motors are similar to switched reluctance motor (which are very large stepping motors with a reduced pole count, and generally are closed-loop 5. Potentiometer is used to control the direction of the motor. Stepper Motors. Same thing when it's time to stop the rotation - you can't just instantly stop generating pulses but have to slow down the frequency until you have reached a speed where the stepper motor is able to finally stop if no more pulses are generated. Its current rating is 2A for each motor. As you rotate the encoder clockwise, the number increase by 1 each "click" and as you rotate it anti-clockwise it decrease by 1 each "click". When you press the key1, the stepper motor will rotate in the counter-clockwise direction.
