Stepper Motors

A stepper motors is a special class of micromotor and is a brushless electric motor. A stepper motor is designed such that the electromagnets and the central iron include gear-like teeth. As the motor rotates, the electromagnet teeth alternately attract the central gear, allowing the motor to rotate incrementally. These incremental rotations are referred to as steps are contribute to higher vibration and noise levels compared to other DC motors.
