A fan regulator is a device that controls or regulates the speed and motion of the fan motor. It is a regulator which varies the voltage across the winding and thus controls the speed. For you to understand a fan regulator, you must have full knowledge of the fan motor.
What Is A Fan Motor
It is a type of induction motor that is mainly used in household ceiling fans. It has the properties and specifications of a normal motor. They consist of a synchronous or asynchronous electric motor with a fan wheel of associated shafts and the connections for the lines. It also includes a stator.
Types Of Fan Regulator
Fan Regulator only comes in four types. These four types are constructed on the same principle and mostly do the same work. However, their construction just differs from one another.
The four types of fan regulators are Resistive regulator; Phase Angle controlled regulator, Inductive regulator, and Capacitive regulator. The capacitive regulator is the latest type of fan regulator and is used a lot today.
Construction Of Fan Regulator
A fan regulator is the most commonly used device in all households. Mostly it is built inside the fan motors, and fans are used in every house today. To understand the working of a fan regulator, we must know what is inside this device and the complete structure of this device.
A fan regulator consists of a resistor R1. Alongside this resistor, a variable resistance or potentiometer R2 is attached. A capacitor plays a vital role in this device; that’s why a polyester capacitor C1 is also inside this device. A DIAC and TRIAC are also in this device. Finally, a single-phase ceiling fan or an AC motor is the most essential part of a fan regulator.
Working Of A Fan Regulator
The primary purpose of the fan regulator is to control the voltage all across the motor as the voltage across the regulator determines the speed. So voltage plays an important role.
Voltages and capacitance are directly related to each other. As the capacitance across the regulator increases, the voltage decreases, and thus the speed of the motor decreases. Thus by employing suitable combinations of the capacitors, a fan’s speed can be regulated on your will.
All the working of the fan regulator depends upon the formula V= Q/C where Q is the charge across the capacitor and C is the capacitance of the motor.
Due to all this working of the fan regulator, it provides power saving at all speeds. It saves a lot of electricity, and your bill consumption is very low, so thus it also protects your money. This device has a very long lifetime, and you don’t need to change them weekly or monthly. So these can also save your money on the replacing purposes.
