Answer Posted / pradeep
servo motor operates on the principle of nonlinear negative
feedback.It only works in closed loop.That means feedback
is necessary for its operation.Feedback is taken by
encoders,generally resolvers.It gives position feedback and
speed feedback which separates it from simple motors.It has
high torque.If there willnot be any position feedback then
it cannotbe a sevo motor.
