Typically a DC motor. Brushes transfer electrical energy to rotating parts and in conjunction with a commutator switch the direction of the current and magnetic field to support the motor's rotation. | Typically a DC motor.

A stepper motor is an electric motor that turns a well define amount ( say 6 degrees ), a step, when connected to the right power source. Repeated activation will cause the motor to move any number of steps in either direction desired. Used for carefully controlled motion. Microcontrollers are often used as part of the drive system for a stepper motor. A stepper motor is basically an AC ( or pulsed DC ) motor and requires a motor driver of some sort. | A stepper motor is an electric motor that turns a well define amount ( say 6 degrees ), a step, when connected to the right power source.

A nice simple way to control the position of an object is to use a servo motor. A servo motor can be any kind of motor that is equipped with a position sensor and a feedback network to control the position.. The information from that sensor is then used to control the motor. In common "RC" servos the sensor is a potentiometer and all the drive electronics are packaged inside the case with the motor. The typical RC servo is powered on 5 volts and takes a PWM signal to control its rotation. Rotation is usually limited to about 90 degrees, and the force at the end of the servo arm ( or horn ) is a few oz. or pounds ( really you should rate it by torque ). Rotation position can be quite accurately controlled, and typically the motor will move in sub second times Sometimes these motors are modified to allow continuous rotation, but then the "servo" is gone from the motor and they do not have their nice ability to set a position. RC Servo motor is vaguely in the $10 range. | A nice simple way to control the position of an object is to use a servo motor.
