BLDC Fans Explained: Know What Makes BLDC Fans A Must Have In Indian Households

Today, the majority of our population uses ceiling fans in their homes. But the most common aspect each buyer considers while buying fans is its energy efficiency, durability, maintenance cost, etc. Today, in this blog, we will discuss BLDC (Brush-Less DC) fans.

BLDCs are energy-efficient fans that have efficient control over rotational speed and torque. These fans operate with electronic commutation and thus eliminate the need for commutators and brushes. Such designs lessen wear and friction, thus requiring lower maintenance and enhancing the lifespan.

BLDC Fans30 watts0.030 units0.45 units164.25 unitsRs. 985.5

On average, in India, the cost of electricity per unit is around Rs. 6 for residential homes. The price differs from region to region, but the average remains around Rs. 6 per unit.

The above table shows that with BLDC ceiling fan, you can save approximately Rs. 1500 in a year. Additionally, Rs. 1500 is the basic price difference between BLDC fans and ordinary fans. Thus, to summarize, if your fan runs for around 15 hours in a day and your electricity cost exceeds Rs. 6/unit, then you will recover the cost invested in the BLDC fan in nearly 2 years in the form of energy savings.

One of the primary advantages of BLDC fans is they are highly energy efficient. Compared to conventional motors, these fans convert more electrical energy into mechanical power and thus ensure minimum wastage.

Let’s discuss some additional advantages of BLDC fans.

Advantages of BLDC fans

●  Lower maintenance cost: BLDC fans don’t use brushes between the rotor and stator. This feature further reduces the maintenance cost.

●  Better Performance: These fans are controlled electronically. Hence they are good at regulating speed and motor torque. Hence these fans give highly-efficient performances.

Durable: As there are no brushes present, the chances of a spark are reduced, which could otherwise cause damage to the motor. This increases the durability of BLDC fans.

●  Lower noise levels: Because of friction, ordinary fans usually cause some degree of noise. However, in BLDC fans, there is zero friction, and hence the noise levels are considerably low.

Lower possibility of failure: BLDC motors work on an electronic control system, while traditional fans work on a mechanical commutation system. Thus BLDC has fewer chances of wear and tear.

More torque: BLDC fans are known for delivering greater torque to give superior performance than regular fans.

Higher efficiency: Because of improved control systems in BLDC fans, monitoring and controlling torque can be done with greater ease.

Lower heat generation: The traditional fan motor contains an electromagnet, which heats the motor and does not cool quickly. In contrast, the BLDC fan motor does not have an electromagnet at the center, which prevents overheating.

BLDC Technology

Although BLDC technology has been in the market for a couple of decades and is widely used in industries for high-torque motors, such technology was never implemented in ceiling fans.

Traditional fans consume a significant amount of energy, typically around 70-90 watts. However, BLDC fans have significantly reduced power consumption by up to 65%, with many models only using 28 watts of energy. Due to this lower energy consumption, these fans can lead to substantial savings on your electricity bills, making them increasingly popular as ceiling fans.

Let’s have a look at some of the salient features of BLDC fans:

●  In-app voice command: You can regulate these fans through your mobile app.

●  Performance analytics: Through mobile apps, you can know the run time, power consumption, and amount of electricity saved with these fans.

Compatibility with Alexa and Google Home: You can link your BLDC smart fans with Alexa or Google Home.

Bluetooth control: Even if you don’t have Wi-fi at home, these fans can switch to Bluetooth when needed.

Sleep mode: As per your setting your smart BLDC fan can decrease the speed after every 2 hours.

●  Smart remote: The BLDC fan remotes can even operate from a distance of 20ft.

●  Fan with LED lights: Many BLDC fans come with LED lights.


To conclude, BLDC fans are undoubtedly a must-buy product for every home. They are energy-efficient, which helps reduce your energy bills, and they come equipped with smart features such as timer and sleep control modes. If you are looking to upgrade your home’s fans, BLDC fans are a smart choice.

Moreover, these fans require less maintenance due to the absence of brushes in their design. Additionally, they operate with less noise and boast greater durability, making them an ideal choice for long-term use.
