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.

Simple servo system block diagram figure 2 3 view a is a block diagram of a closed loop position servo. This is the summation or sum point where the input signal and the. Below is the illustration of the various system level. The block diagram representation of the armature controlled dc servo motor is developed in steps.

The schematic diagram of servo system for ac two phase induction motor is shown in the figure below. Note the greek letter sigma meaning summation aka the controller surrounded by a circle. Usually the inductance of the armature winding is small and hence neglected. 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.

Let us consider the armature controlled dc servomotor as shown in figure 1. Block diagram of a position servo. 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.

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. This will give accurate and stable control over speed and position. 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.
