IT WORKS ON THE PRINCIPAL OF FEEDBACK AND COMPARISION SYSTEM

Answer / vijay

A Servo is a small device that has an output shaft. This
shaft can be positioned to specific angular positions by
sending the servo a coded signal. As long as the coded
signal exists on the input line, the servo will maintain the
angular position of the shaft. As the coded signal changes,
the angular position of the shaft changes. In practice,
servos are used in radio controlled airplanes to position
control surfaces like the elevators and rudders. They are
also used in radio controlled cars, puppets, and of course,
robots

Servo motors are used in closed loop control systems in
which work is the control variable

Answer / santosh gadad

BASICALLY IT WORKS ON A ELECTRO MAGNETIC INDUCTION
servomechanism, or servo is an automatic device that uses
error-sensing negative feedback to correct the performance
of a mechanism. The term correctly applies only to systems
where the feedback or error-correction signals help control
mechanical position or other parameters. For example, an
automotive power window control is not a servomechanism, as
there is no automatic feedback that controls position—the
operator does this by observation. By contrast the car's
cruise control uses closed loop feedback, which classifies
it as a servomechanism.
