A servo motor is a rotary actuator or linear actuator that allows for precise control of angular or linear position, velocity, and acceleration. It consists of a suitable motor coupled to a sensor for position feedback. It also requires a relatively sophisticated controller, often a dedicated module designed specifically for use with servomotors.
Servomotors are not a specific class of motor, although the term servomotor is often used to refer to a motor suitable for use in a closed-loop control system.
Standard servos, though, can only rotate through about 180-degrees. Although you can purchase modified servos that will rotate infinitely in either direction, the standard 180-degree servos are more commonly available, are usually cheaper, and you may already have a couple lying around from an old RC car.
Servomotors are used in applications such as robotics, CNC machinery or automated manufacturing.
Servos are controlled by sending an electrical pulse of variable width or pulse width modulation (PWM), through the control wire.

There is a minimum pulse, a maximum pulse, and a repetition rate. It can usually only turn 90° in either direction for a total of 180° movement.
