DC Motors
There are several kinds of DC motors, examples are stepper motors, servos, brushed/brush-less motors.
Stepper motors: The inputs of a stepper motor are signal pulses and the shaft of a stepper motor moves between discrete postions proportional to pulses. If the load of the motor is not too great, open-loop control is usually used to control the motor. Stepper motors are used in disk drive head positioning, plotters, and numerous other applications.
Servo motors: The input of a servo motor is a voltage value and the output shaft of the servo motor is commanded to a particular angular position according to the input voltage. Servo motors are used in radio control airplanes to control the position of wing flaps and similar devices.
DC motors: The input of a DC motor is current/voltage and its output is torque (speed).
