Servo Motor Control System Block Diagram

Below is the illustration of the various system level.

Servo motor control system block diagram.

Working principle of ac servo motor. Block diagram of a position servo. Field controlled dc servo motor. Note the greek letter sigma meaning summation aka the controller surrounded by a circle.

The field servo motor. Simple servo system block diagram figure 2 3 view a is a block diagram of a closed loop position servo. 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.

They typically include a servo system that consist of feedback elements and motor driver combined in a manner. This is the summation or sum point where the input signal and the. Usually the inductance of the armature winding is small and hence neglected. This will give accurate and stable control over speed and position.

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. The back emf is proportional to the speed of the motor and hence. 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. After reading this topic armature controlled dc servomotor in the control system you will understand the theory derivation expressions transfer function and block diagram.
