Stepper motors are synchronous motors in which the rotors can be turned through an angle. This means that any angle of rotation can be turned in several steps. Stepper motors are often used in printers, as they follow the externally applied field precisely and can be operated without sensors for position feedback. Their easy and precise control via software also makes them suitable for use in robots. We have a large selection of stepper motors from Pololu, Sparkfun and more in our online shop.
