Stepper Motor

Abstract

A stepper motor is a digital device which is like a computer that runs on pulses. It can be directly connected with digital computer unlike D.C. motor for which A/D or D/A converters are needed. In fact, stepper motor is an electric motor which moves or rotates in series of small discrete steps. A stepper motor is an electromechanical device which converts electrical pulses into discrete mechanical movements. In this chapter, the authors discuss the stepper motor. It starts with the definition of stepper motor, its basic function, and principle of working. They then discuss the types and construction of stepper motor. Finally, this chapter concludes with the applications of stepper motor.
