80ST 400W 1.27N.m 2.8A 3000rpm Ac servo motor with driver for CNC router
AC Servo motor Introduction:
A servo motor is an electromechanical device that produces torque and velocity based on the supplied current and voltage. A servo motor works as part of a closed loop system providing torque and velocity as commanded from a servo controller utilizing a feedback device to close the loop.

Drawing of Servo motor:
Servo motor Features:
These are low weight devices.
It offers reliability as well as stability in operation.
There is not much noise generated at the time of operation.
It offers almost linear torque-speed characteristics.
As brushes and slip rings are not present here thus it reduces
maintenance cost.
Applications of AC Servo motors:
Due to the various advantages offered by the AC servomotors, these majorly finds applications in the instruments that operate on servomechanism, in position controlling devices, computers. Along with this these also find applications in tracking systems, machine tools and robotics machinery.
