Stepper motors are DC (direct current) electric motors designed for precise motion control. They consist of multiple sets of coils and magnets which are designed to allow rotor movement in angular increments called steps. Stepping can be done in full step, half step or other fractional steps in both forward and reverse. Stepper motors are rugged, reliable, cheap, and easy to control devices that produce high torque at slow speeds. They are used in a variety of applications and equipment, including machine tools, process control systems, and tape and disk drive systems.

 Stepper motor systems consist of two basic components: an electric motor and a controller system. During operation, a controller supplies pulses to a driver, which interprets these signals to send proportional voltage to the motor. This voltage is applied to poles around the rotor which energizes the coils or changes their polarity. The resulting magnetic interaction between the poles and the rotor causes the rotor to move and produce the torque required for the application. This movement is done in equal angular increments called "steps".
