Electricity Saving Tips For Homes And Offices

Choose the right Regulator for Ceiling Fan for Electricity Saving

By on April 28, 2015

Ceiling fan is one of the most common appliances in Indian household. Being a tropical country, India relies a lot on ceiling fan and there is a ceiling fan in every room in the country. When we go and buy a ceiling fan, we also get a regulator along with it. Regulators are of different types, and different ceiling fans come with different types of regulators. Most people typically do not care about the regulator, but it is very important to know that even the regulator can waste electricity and can increase your electricity bills.

Fan Regulator

Good news is that you can always refuse to take the supplied regulator and can get equivalent discount, and replace it with an efficient one. But for that you need to know about the types of regulators.

How does a Fan Work?

A ceiling fan has an electric motor and metallic blades connected to it. When we switch on a fan, the voltage difference causes the current to pass through the motor and the fan rotates. The regulator controls the voltage that makes the current flow less or more. Lower the voltage lower the speed of the fan. So a regulator controls the voltage levels for the fan.

Types of Regulators

There are 3 types of regulators available in the market today: Electric Regulator, Step Type Electronic Regulator and Movable Electronic Regulator. All 3 have different ways of controlling the fan speed and thus the efficiency with which they manage electricity consumption differs. From price perspective Electric regulator is the cheapest, but of all three it is the most inefficient regulator. We are in process of compiling information related to price impact and will update that as well very soon. But first let’s look at all the three types:

Electric Regulator

Traditional regulators that were there in our homes in the past were mostly of this type. These regulators have resistors to decrease the voltage for the ceiling fan. The resistor heats up while decreasing the voltage and thus the electricity saved by reducing the fan speed is lost as heat in the regulator. The internal heat also damages the regulator in long run. These regulators are also bulky in size. They come for as low as Rs 40 a piece.ElectricRegulator

Electronic Regulator

Electronic regulators are the latest type of regulators available in the market. These are much smaller in size than the electric regulators. Electronic regulators use capacitors instead of resistors to decrease the voltage. Capacitors regulate the fan speed by regulating the waveform of power supply. These do not get heated up and thus save electricity when the fan is running at lower speeds (at higher speeds electricity consumption of fan is the same with both regulators).  These regulators save up to 40% at speed 1 and about 30% at speed 2 compared to electric regulators. There are 2 types of electronic regulators available:

    1. Movable Type: These regulators move smoothly and there are no stepped number (1 to 5) provided on theem. These regulators are better than electric ones but still can cause some distortion to the movement of the motor that causes it to heat up. This type typically costs Rs 100 apiece.MovableType
    2. Step Type: These regulators have numbered speed steps (typically 1 to 5). These regulators provide lower distortion to the movement of the motor and thus less heating. These are the most efficient type of regulator. This type typically costs Rs 200 apiece.ceiling_fan_regulator

If you run fans at low speeds in your house then a step type fan regulator is the best electricity saving option for you. Savings in electricity bills can recover the extra price you pay for it.Infographic11.png.png

I have 4 Crompton Greves (Model-High Speed) ceiling fans. The fan runs at very speedily even at level 1 and thereafter runs very fast at each level. Sometimes the speed gets unbearable for us specially during Rainy and Winter seasons. The regulators are not from the Crompton Greves.
Please suggest some solutions for this problem.

I’ve 4 electronic step type and 1 electric regulator in my home. Electric one is working fine while all the other electronic have problems of very low speed at 1-2-3-4 and very high speed at 5. After reading the comments here I learned that lot of people are facing these problem. I think either these regulators are of bogus quality (including branded regulators) or there is a problem with this technique of regulating fan speed.
We have sent satellite to Mars, can’t we have a good fan regulator.

Hi, I am using Orient wendy fans with Step Type electronics regulator. My both fans can not speed up in level 1,2, and 3. On level 4 they rotate at high speed. But in level 1, 2, and 3 they both are running at too slower speed. First 3 level can not make difference in fan speed. I also have contacted technician. But technical suggest us to use old Electric Regulator. What should I do? I am totally fainted with technician’s suggestion. Please help…..

The problems is only with Orient fans. The same regulators are working well with USHA fans in my house.

I too have Orient PSPO Fans and step type electronic regulators and after having replaced all regulators periodically not even a single regulator has been able to sustain for any long.
Do you mean the step up electronic regulators are a FAILED TECHNOLOGY and still being allowed to sell by Electrical authorities in the country and there is no quality control mechanism ?
Moving back to older technology of electric regulators that work on resistors is not a practical option as most homes do not have space in the board nor is it updated technology.
Regulators are meant to regulate speed for our comforts and not that we align our way of living as per capacitors wishes.
We expect a solution through this medium, else whats the point in having such forums online to just accept what is thrown by these vendors at us.

I am guessing I have the capacitor based regulators installed (they are not the older big protruding box type but small ones the same size as the switches themselves built into the board and the dial turns freely instead of in ‘clicks’ and speed of the fan is changed accordingly. Interestingly I found that it works with superfan also. The way I realized was that one day the knob was turned all the way down to ‘zero’ position and the fan won’t work at all – I didn’t notice it and I started worrying that my superfan, which I bought against the wisdom of my family members, has failed me. Then I noticed the knob and turned it to ‘full’ and thank goodness the fan started working again.

Secondly, I have a query based on a mistake made when the house wiring was done. In one of the bedrooms, the regulator is connected to the tubelight point instead of fan. So when I turn the dial, the tubelight (regular 36W T8) starts dimming and after a certain point it turns off. I am thinking of replacing this with an LED tubelight shortly so is it possible to continue using that regulator as a dimmer? Would I be doing any harm to the LED tubelight or any of it’s components? Is there any difference between using this one and an actual dimmer?

We have new ceiling fans in our home, there is step type regulators installed for each fan. At no. 5 these fans runs fast but at no. 4 they go very slow as if they are being run on no. 1 or 2. we have tried changing the regulator but of no use. Pls advise as it causes very discomfort to be in Very fast air when not required

I have brought a high speed ceilling fan. is it safe to Controlling it with Step Electronic regulator?

Hi Team,

I have recently purchase online an Ovastar Hand Blender-Mixer (OWHM-1014) most possibly china made, Delhi marketed. This has 5 speed settings probably field or winding tapped universal motor with carbon brushes and o/p 250W. I have used it a few times to make cakes and cookies and found that the RPM of speed setting 1 itself is so high, that there’s very small variation of RPM in other higher settings (one can say hardly any difference between speeds 1 to 5. I’d like to reduce the speed at point 1, 2 & 3.

Can you advice if adding some resistance or inductance/capacitance or triac-diac in the speed controller’s circuit points at 1-3 would help regulate the RPM of the motor to desired level? Or can I use regular ceiling fan regulators available in the market?

I am using capacitive type regulator.1.1 MFD,2.2MFD 3.3MFD capacitance are using.But variation in speed is too high.All five regulators have same problem.Can I increase the speed by increasing the capacity of the capacitor.
