What is a BLDC motor?

A brushless direct current (BLDC) motor is a type of electric motor that uses an electro-magnet to generate electricity. The magnets are located inside the rotor, which spins around in a fixed position on its shaft. As this occurs, it creates a magnetic field that moves back and forth through wires attached to each pole of the magnet.

These two poles are arranged, so that their polarities are not aligned with each other at any given point during operation; instead, they're perpendicular to one another—they're 'hyperextended' as it were—and produce currents along them as they rotate past each other. It allows for high power output because there's no need for friction between parts such as bearings or gears, which would otherwise slow down rotation speed and reduce efficiency.

Why do ceiling fans use BLDC motors?

A BLDC motor uses an electronic speed controller (ESC) to adjust the amount of power sent to each armature. The speed controller watches for changes in current and voltage, then adjusts its output accordingly. It allows it to operate at a much lower frequency than traditional DC motors—a result that makes them ideal for use in ceiling fans because they're so efficient at transmitting energy down their shafts without creating too much noise or vibration.

Benefits of fans using BLDC motors:

  1. The advantage of brushless direct current (BLDC) motors is that they are more energy efficient. The BLDC motor uses less power than the traditional AC (Alternating current) and DC (Direct current) counterpart motor. Hence, it can lead to significant savings when running your ceiling fan.
  2. Another advantage of using a BLDC motor in a ceiling fan is that they are quieter than traditional AC (Alternating current) and DC (Direct current) fan units. It means you can enjoy your favourite music or television show without worrying about the noisy sound of the fan, or you can sleep through the night without waking up to loud noises or vibrations caused by the fan.
  3. The BLDC motor is designed to help reduce the weight of ceiling fans and makes them easier to install in any area of your home or office. 
  4. Additionally, since they do not require much maintenance compared to traditional motors, they are also very durable—meaning less frequent servicing costs over time.


Many people think ceiling fans are just decorative pieces of equipment. That's true, but they're also great tools when it comes to regulating the temperature in your home and business space. 

A brushless direct current (BLDC) motor is used in ceiling fans because it is more efficient and reliable than its predecessors. It uses fewer parts, is easier to maintain, has a longer lifespan, and requires less maintenance than a regular traditional motor.

Now that you know about the BLDC motor, you can make informed decisions if you intend to buy or purchase one. Well, Anemos gives you the power to choose one of the best BLDC ceiling fans based on your needs/requirements.
