Servo Motor Control System Block Diagram

They typically include a servo system that consist of feedback elements and motor driver combined in a manner.
Servo motor control system block diagram. Usually the inductance of the armature winding is small and hence neglected. Briefly a typical motor drive system is expected to have some of the systems block diagram indicated in figure 27 1. The field servo motor. 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.
Note the greek letter sigma meaning summation aka the controller surrounded by a circle. The back emf is proportional to the speed of the motor and hence. Below is a block diagram of a modern automated systems incorporate closed loop feedback for motion control. Let us consider the armature controlled dc servomotor as shown in figure 1.
The schematic diagram of servo system for ac two phase induction motor is shown in the figure below. This will give accurate and stable control over speed and position. Block diagram of a position servo. This is the summation or sum point where the input signal and the.
Working principle of ac servo motor. Below is the illustration of the various system level. Field controlled dc servo motor. After reading this topic armature controlled dc servomotor in the control system you will understand the theory derivation expressions transfer function and block diagram.
