A Stepper Motor is one of the most common motors used to control mechanical machines such as printers, scanners and CNC Machines.

Bipolar Stepper Motor

Bipolar Motor Diagram

Bipolar motors typically come in a 4 wire configuration only, though a 5, 6 or 8 wire motor can also be wired as a Bipolar motor by leaving the inner coil lines unconnected.

Unipolar Stepper Motor

Unipolar Motor Diagram

A Unipolar motor is often the simplest type of motor to drive electrically as the common wire in the center of the coil allows for the direction to be reversed by simply powering the opposite ends of the coil. Typically the common wires are connected directly to a high voltage DC power supply, and the ends of the A and B coils are alternatively connected to ground.

Unipolar motors typically come in 5, 6 or 8 wire configurations, in all cases the inner wires of the coil are all wired to a common point. A Unipolar Motor can be wired as a Bipolar Motor by leaving the common lines unconnected.
