A fan consists of an electric motor and several metal blades (usually 3), attached. When we switch on a fan, current passes through the motor to account for the voltage difference and as a result the fan rotates. The regulator controls the voltage of the motor and decreases or increases the amount of electricity flowing through the motor.
Therefore, the voltage level control of a fan is completely dependent on its controller. And the amount of voltage of a fan is proportional to its rotation speed, that is, as the voltage increases, so does the speed of the fan.
An electric fan is a very necessary device in summer. And the speed of this machine is controlled by the regulator. That is, the regulator is important along with the fan. Because without a regulator you cannot increase or decrease the force/speed of your fan. And almost all of us have a curiosity that if the fan speed is reduced with the regulator, will the power consumption be reduced? Or is the power consumption the same when driving hard and slowing down? Today I will discuss with you about this matter. Let’s begin then.
If the question is asked somewhere, ‘does the power consumption remain the same or does the consumption decrease if the fan speed is reduced?’ So this question can be answered in two ways. Some say electricity consumption will remain the same. Others say that electricity consumption will decrease. Both of their answers are fairly correct. Are you getting confused? Actually, whether the electricity consumption will decrease or not, it will depend on the type of regulator you are using. Regulators are generally of two types:
- Electrical Regulator (Resistor Based Regulator).
- Electronic regulator .
If you use an electrical regulator, the power consumption will remain the same whether you increase or decrease the speed. Again if you use an electronic regulator, then reducing the speed will reduce the power consumption, increasing the speed will consume more power. Now let’s know how to recognize electrical and electronic regulator.
Which is an electrical regulator?
It is basically a wirewood resistor based regulator. The large regulators that were used in the past took up more than half of the switch board space and were very hot. If you can open it, you will see that there is an iron core or body with a lot of copper wire twisted around it.
Which is electronic regulator?
It looks very small in size. Almost equal to a switch. A switch on a switchboard occupies space equal to Gets very little hot. If you can open it, you will see that it is a small circuit made of a variable register, one or a few fixed registers, triac and diac.
Electrical Regulators: Electrical regulators are made basically by winding copper wire on an iron core. As electricity travels long distances through these wires, some of the electrical energy is converted into heat energy. As a result the fan does not get full power and the rotation/speed of the fan decreases. The basic electricity consumption remains the same. That is, even if the fan speed decreases, the power consumption does not decrease. This is because some of the power in the regulator is wasted in heat energy, causing the fan to draw less power and spin slower.
Electronic Regulators: Electronic regulators are generally made up of a variable resistor, one or more fixed resistors, triacs and capacitors. Triac plays a major role here. A thyristor type electronic switching device is made with fixed resistors, capacitors and a variable resistor along with the triac. It basically slows down the fan speed by very fast switching i.e. switching the connection on and off. Supplies the amount of power you set and the regulator itself dissipates very little power. By reducing the speed of the fan, the power consumption is also reduced.
Energy drinks and electric fan speeds are discussed as examples
Imagine a scenario. Imagine you run down the street. Now you need energy to run. So you had an energy drink. After consuming an energy drink, you started running vigorously. Note that the road is not completely smooth. There is also a friend section somewhere. In this case, the nature of the road acts as your speed controller. The relationship between electric fan, electricity and regulator is similar.
A fan consists of an electric motor and several metal blades or wings (usually 3) attached. When we turn on a fan switch, current passes through the motor to account for the voltage difference and as a result the fan rotates. As if you started running full speed after consuming an energy drink. The regulator controls the voltage of the motor and decreases or increases the amount of electricity flowing through the motor. Just as the nature of the road dictated your running speed. Therefore, the voltage level control of a fan is completely dependent on its regulator. And the amount of voltage in a fan is proportional to its rotation speed. That is, as the voltage increases, the speed of the fan will also increase. As the story goes, the more energy drinks you consume, the more energy you will run.
What can be done to prevent electricity wastage:
Currently, there are reports of load shedding from various parts of the country for several days. The government says that due to the disruption of electricity generation due to gas shortage, electricity load shedding has to be done. We waste a lot of electricity every day without realizing it. At the same time, there is the amount of technology that is increasing day by day. While using electricity, whether it is being wasted or not should be kept in mind. Let’s know what can be done to prevent power wastage-
- If good quality electronic ballasts (chokes) can be used instead of using electrical ballasts (chokes) in tube lights, the electricity bill will be much lower.
- Turn off oven, fan, AC and PC unless necessary.
- Make it a habit to switch off AC, light, fan while leaving the house
- Give up the habit of running the oven. Especially the microwave. Do not use rice cookers, curry cookers, etc. unless absolutely necessary
- Reduce the use of geysers or heaters for heating water.
