BLDC- Brushless Direct-Current motors convert electric energy to mechanical energy. Intelligent speed control, high torque, and low maintenance characterize DC motors. Robotics and heavy-duty vehicles are among the fields of application for DC motors. A closed-loop controller receives power from the BLDC through an inverter.

The revolutionary feature makes the BLDC motor a futuristic need.

1. Robotics and heavy-duty vehicles are among these industries.

2. A closed-loop controller receives power from the BLDC via an inverter.

3. Current passes to its windings to control the speed and torque of the control unit.

4. BLDC motors have high efficiency, with low maintenance requirements. 

5. They are more stable and long-lasting.

What is BLDC Fan Technology?

BLDC fan technology is creating a buzz in the market. It is energy efficient and helps in cost-cutting over electricity bills. A brushless direct current motor (BLDC) functions on direct-current electricity. BLDC motors contain permanent magnets rather than electromagnets used in induction motors.

The permanent magnet contains less heat loss and energy compared to electromagnets. A BLDC motor converts alternate current into DC. That works at power fluctuations and on low voltage. The BLDC Fan Technology in Energion Stylus helps save energy and makes your living room more stylish and aesthetic.

The BLDC motor has three working components: the rotor, stator, and shaft. It uses a sequence of gears to convert electrical into mechanical energy. A BLDC fan driver attains their power from SMPS.

Advantages and Disadvantages of BLDC Fan

Like every technology has two sides: BLDC fans also have advantages and disadvantages.

Advantages of BLDC fans

1. Traditional Ceiling fans run on AC motors. Yet, fans with BLDC technology use brushless DC engines that cut power consumption by 65%.

2. BLDC winding has thick copper cables to ensure a longer lifespan with low winding issues. These fans do not get overheated.

3. The carbon brushes are absent from the rotor and the stator of the BLDC fan. Hence, there is no hidden maintenance cost involved in the replacement of brushes.

4. BLDC fans maintain high torque to secure high-quality performance.

5. An induction motor has carbon bruises that create friction, which creates noise. A BLDC fan has zero friction, hence creating minimal noise.

6. BLDC motors comprise electronic control systems. That promotes fewer possibilities of collapse because of wear and tear. An induction motor fan has a mechanical commutation unit.

Disadvantages of BLDC fans

1. BLDC fans are expensive compared to an induction motor fan. The setup comprises an electronic controller in BLDC. An ordinary fan motor has an inexpensive mechanical commutation system.

2. BLDC fans produce minimal vibrations at low voltage, which causes resonance. But, it is adjustable.

3. The BLDC technology is new to fans, and it is difficult to find an experienced technician to install it.

4. BLDC motor has complicated wiring to install. Because of the presence of an electronic control unit that links to electromagnets

Importance of BLDC fan in Day to Day Life

Fans are an integral part of every individual’s life, irrespective of weather. We don’t realize that the fan runs for hours and consumes more units than a refrigerator. Fans are the major contributor to our electricity costs.

1. BLDC fans consume considerate power. It consumes a minimal current lowered by 65% compared to an induction motor fan.

2. BLDC motor runs on low current so can run longer on solar, regular, and inverters.

3. They operate on a remote control that promotes luxury and comfort hand-in-hand.

4. BLDC fans provide a comfort zone by facilitating timer and sleep mode as functions.

5. BLDC fan has the next-generation technology. That facility sets specifications like speed reduction at different points in time

How much money does a BLDC fan save in a year? 

Calculate your savings on BLDC fans here

An ordinary induction motor fan consumes about 80 Watts. A BLDC motor fan’s 35 Watt consumption. We operate a fan for almost 8 hours, 365 days per year. Let’s assume the residential power consumption rate is Rs 7 per unit.

A traditional fan will consume around 233.6 units (80 Watts 0.08*8*365) that cost around Rs 1635.2 (233.6 units * 7)

A BLDC fan consumes 87.6 units (30 Watts = 0.03*8*365) that costs around Rs 613.2 (87.6*7)

That saves us around Rs. 1022.per year. Most fans work 8+ hours per day goes up to 1500-2000 bucks.
