Stepping motors fill a unique niche in the motor control world. These motors are commonly used in measurement and control applications. Sample applications include ink jet printers, CNC machines and volumetric pumps. Several features common to all stepper motors make them ideally suited for these types of applications.

The following sections discuss the most common types of stepper motors, what circuitry is needed to drive these motors, and how to control stepping motors with a microcontroller.
