Servo Motor Control System Block Diagram

Working principle of ac servo motor.

Servo motor control system block diagram.

Simple servo system block diagram figure 2 3 view a is a block diagram of a closed loop position servo. In this the reference input at which the motor shaft has to maintain at a certain position is given to the rotor of synchro generator as mechanical input theta. The load may be a conveyor system a traction system the rolls of a mill drive the cutting tool of a numerically controlled machine tool the compressor of an air conditioner a ship propulsion system a control valve for a. Note the greek letter sigma meaning summation aka the controller surrounded by a circle.

The block diagram representation of the armature controlled dc servo motor is developed in steps. After reading this topic armature controlled dc servomotor in the control system you will understand the theory derivation expressions transfer function and block diagram. Block diagram of a position servo. Usually the inductance of the armature winding is small and hence neglected.

The back emf is proportional to the speed of the motor and hence. Below is the illustration of the various system level. This is the summation or sum point where the input signal and the. Briefly a typical motor drive system is expected to have some of the systems block diagram indicated in figure 27 1.

Below is a block diagram of a modern automated systems incorporate closed loop feedback for motion control. This will give accurate and stable control over speed and position. The field servo motor. They typically include a servo system that consist of feedback elements and motor driver combined in a manner.
