Servo Voltage Stabilizer

A Servo Stabilizer is a Servo motor controlled stabilization system that performs optimum voltage supplyusing a Buck Boost transformer booster that captures voltage fluctuations from input and regulates current to the correct output. An AC synchronous motor adjusts voltage in clockwise or anticlockwise direction and manages the output voltage with components like control card.dimmer.comparator, transistors, mocs, etc.

Main Components & their Functioning There are seven main components in a servo voltage stabilizer: -
  1. Dimmer (Variable Transformer)
  2. Buck Boost Transformer (Series Transformer)
  3. Servomotor - Synchronizing Motors
  4. Contactor or Relay
  5. MCB, MCCB
  6. Electronic Circuit
  7. Corbon Brush

1. Dimmer (Variable Transformer)
It is normally round in the shape. Silicon CRGO toroidal core is used for the base & copper wire with specific turn ratio according to the capacity is used. The basic purpose of dimmer is to increase or decrease the voltage which is fed to the buck boost transformer. 50% of the output voltage is increased or decreased by dimmer only. Let us take an example: If the input voltage is 160V, the dimmer will increase it to 190V & rest of the 30V (sınce 220V is required to run any single phase load) will be done by Buck Boost Transformer

2. Buck Boost Transformer
Contrary to dimmer it is in rectangular shape. Bobin is fitted with The CRGO core. When the transformer structure is built, it is dipped in varnish tank for extra protection. This type of Insulating varnish atso called transformer varnish is put on all the windings used in buck boost transformers to encapsulate them before the whal servo stabilizer is ready for regress testing. Transformer varnish enhances coil life and protects windings in the transformer from environmental exposure that would otherwise get damaged due to vibrations. This varnish can be used as a great insulator for any coil of wire.

3. Servomotor (Synchronizing Motors)
Servomotor as the name suggests is the main part of servo stabilizer. The motor rotates the arm connected on the dimmer in clockwise or anti clockwise direction according to input voltoge.

4. Carbon Brush
This is a moving part in servo stabilizer, it is fitted in the shaft to make the contact with dimmer. If the input voltage variation is very frequent, this carbon brush will erase early and customer has to replace it very frequently. That is why servo stabilizer manufacturer should use best quality carbon brush.

5. Contactor
The function of contactor is to cut the output of any servo stabilizer if it exceeds a prescribed limit.

The MCB is used to switch on loff the servo stabilizer and gives short circuit protection whereas MCCB is normally for overload protection.

7. Electronic Circuit
As the name suggests, it sends the signal to various parts of a servo stabilizer like motor, dimmer, etc. so it works according to that signal & does their part to correct the voltage. Why do I use a Servo stabilizer.
