If cutting down on your monthly electricity bill sounds like a good plan, rethinking your ceiling fan might be the way to go. This is beneficial in several ways that you may have not thought about before.
First of all, whether you realize it or not, due to the climatic conditions, especially in India – the ceiling fan is running almost all day, sometimes in several rooms. This promotes air circulation and cools down the room on far less power usage than an air conditioner.
This continuous use of fans makes power saving far more useful – as the usage is much more. Another reason why this is a great idea is the limited investment it requires.
When investing in power-saving appliances we tend to think of heavy electrical items like washing machines, air conditioners, or refrigerators. Ceiling fans are cheaper than these appliances but can equally save power and money.
Conventional ceiling fans have existed over several years- all with the same motors which consumed more or less the same power.
These motors, known as induction motors use around 70-80 Watts – however, this is no longer the only option.
With technology constantly improving, ceiling fans have begun to incorporate motors that consume less power and have a longer life.
One such option available in the market is BLDC fans.
What are BLDC fans?
BLDC, which stands for brush-less direct-current motor contrary to the electromagnets in conventional induction motors uses a permanent magnet.
The permanent magnet generates a DC (Direct Current) magnetic field instead of the AC (Alternating Current) magnetic field that induction motors produce by passing AC current through the electromagnet.
The magnetic field generates motion, and depending on the current, can control and vary the speed of motion.
Also, the BLDC motors have an in-built inverter to convert DC to AC.
This allows the fans to consume lesser electricity, without negotiating on speed or air delivery. These BLDC motors also have other advantages like lowered noise generation, lighter and longer lifespan when compared to their induction motor counterparts.
Advantages of BLDC fans:
- Consumes far lower energy than its counterparts. In fact, where the regular motor consumes 70-80 Watts, the BLDC motor only needs 30-35 Watts. This reduced consumption results in up to 65% saving on the electricity bill.
- BLDC motors produce less heat as compared to induction motors on traditional fans. Since less electricity is lost in heat generation, the motor is far more efficient.
- These motors are more powerful and can offer a larger range of speeds for the operation of your fan. This is especially useful when the fan has to cover a larger area and circulate more air at higher speeds since BLDC motors can go up to 10,000 rpm.
- Since it consumes lower power, it can run for longer on backup power. This includes inverters or even solar power batteries.
- This motor is designed to undergo less wearing over the years of usage and will thus provide a longer lifetime for your fan as compared to other conventional motors in the fans.
- BLDC fans are also a lot less noisy as compared to the induction motor powered fans, and can even run at high speeds with low noise production.
Disadvantages of BLDC fans:
- Although for household purposes BLDC motors promise better efficiency, when it comes to industrial application induction motors are a better choice. This is because magnetic losses tend to increase with an increase in machine size.
- Since this is a new and upcoming technology, finding service centres or repair shops for these motors may be a little harder than finding something for the induction motors that are well known and understood among mechanics.
BLDC fans versus Normal ceiling fans
Akin to the transition from incandescent lights to LED bulbs, the emergence of BLDC fans seems promising enough to replace the popular traditional induction motor fans.
This is mainly due to the amount of power it saves and as a result of which the money it can save on electricity also.
Below is a quick comparison between the power requirements of a BLDC fan versus that of an induction motor fan for various speeds, varying from 1 to 5.
To change the speeds on a regular ceiling fan it uses a regulator, which may be one of two types.
1. Resistance Based: The resistance of the regulator is varied to alter the voltage supplied to the fan. However, this is not an efficient option as a lot of energy is lost as heat energy due to resistance.
2. Switch Based: Another type, more commonly found these days functions by cutting down the voltage to alter the speed of the fan. This switch-based fan has replaced most of the resistance-based options that were once in the market.
Contrary to all this, a BLDC fan takes in AC voltage and internally converts it into DC using SMPS. This is the main difference between BLDC and regular ceiling fans and is known as the commutation method.
In other words, this is the technique of altering the direction of flow of current in the motor responsible for the rotational movement.
Since BLDC motors lack the brushes, the commutation is done through the electronics part of the motor via a pre-set algorithm.
This is beneficial since over a period of time, due to mechanical contact in a brushed motor, the regular ceiling fan induction motors undergo wear and tear.
However, this frictional contact is eliminated in the BLDC motor making it more reliable in the long term.
Most trustworthy BLDC Ceiling Fans in India:
BLDC fans are popular in the market from an array of manufactures.
This ranges from those specializing in BLDC and other power consumption technology to brands that have stood the test of time and remained popular in the conventional fan market as well.
