Servo Motor Control System Block Diagram

Block diagram of a position servo.

Servo motor control system block diagram.

The block diagram representation of the armature controlled dc servo motor is developed in steps. This will give accurate and stable control over speed and position. After reading this topic armature controlled dc servomotor in the control system you will understand the theory derivation expressions transfer function and block diagram. Let us consider the armature controlled dc servomotor as shown in figure 1.

Field controlled dc servo motor. 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 back emf is proportional to the speed of the motor and hence.

This is the summation or sum point where the input signal and the. The schematic diagram of servo system for ac two phase induction motor is shown in the figure below. Below is the illustration of the various system level. 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.

Briefly a typical motor drive system is expected to have some of the systems block diagram indicated in figure 27 1. They typically include a servo system that consist of feedback elements and motor driver combined in a manner. Usually the inductance of the armature winding is small and hence neglected. Working principle of ac servo motor.
