Stepper Motor (unipolar)
Stepper motors are very accurate motors that are commonly used in computer disk drives, printers and clocks. Unlike dc motors, which spin round freely when power is applied, stepper motors require that their power supply be continuously pulsed in specific patterns. For each pulse, the stepper motor moves around one ‘step’, often 7.5 degrees (giving 48 steps in a full revolution).
There are two main types of stepper motors - Unipolar and Bipolar. Unipolar motors usually have four coils which are switched on and off in a particular sequence. Bipolar motors have two coils in which the current flow is reversed in a similar sequence.
