Servo motor means it will run at a "constant torque in
varable speeds"

Answer / prmdptl2009

servo motor is a AC motor which is having high speed and
high torque.even it is having torque higher then then that
of stepper motor.in stepper motor pulse signals are used to
control the motion while in servo motor modulated signals
are used.

Answer / ashwin reddy

Hi there, I am ashwin.. As of i know,

AC Servomotor is a two phase induction motor which has two
windings. The control winding and the reference winding. As
we vary the control Voltage, The flux linking the reference
winding ahd the control winding increases thus the back emf
increases.

We know that back emf ios directly proportional to the
speed, even the speed increases. As we can vary the postion
and obtain a suitable torque!

Answer / bhupal singh

A servomotor (servo) is an electromechanical device in which
an electrical input determines the position of the armature
of a motor. Servos are used extensively in robotics and
radio-controlled cars, airplanes, and boats.

What is principal to reduce earth leakage current with isolation transformer? When isolation transformer is installed in input stage of system, earth leakage current is reduced. the reason is why the leakage current of 2nd stage of isolation transformer does not affect the 1st stage's leakage current. I would like to know the reason. As you know, earth leakage current is a kind of AC. So, How to reduce earth leakage current in case that isolation transformer is used?
