The basic principles of stepper motors are explained. Under certain circumstances it is shown that a stepper motor may be a better option than a servo motor. The three most common types of stepper motor are described and their important characteristics are illustrated and explained. Finally, the principles of stepper motor drives and the various types available are analysed.
