For the past few years, we have heard the terms BLDC fan, BLDC ceiling fan, and BLDC motor, which are nothing more than new ceiling fan technology. While traditional ceiling fans have been tried and tested and are now nearly 100 years old, BLDC technology is new and highly efficient in energy consumption and silent operation.
If you are thinking and are one of those curious about this new BLDC Fan technology and why it is so different from a regular fan, then continue reading. Then, in this guide, we will learn everything there is to know about the BLDC ceiling fan.
As you may recall, we used to buy new fans with a warranty of 2-3 or 5 years, but they will last for the next 10 to 20 years if the capacitor or coil is replaced when it burns out. But times have changed, and we now have new technology for the BLDC fan, and in the article What is a BLDC Fan?, we will know the BLDC Fan price, BLDC Fan features, why a BLDC Fan is different from a normal ceiling fan, compare it to a normal fan, and learn everything step by step.
What is BLDC Fan (What is BLDC Motor)
Let’s know the full form of BLDC, which is a brushless direct current fan. “BL” and “DC” are associated with brushless and direct-current fans. A BLDC ceiling fan is one type of ceiling fan that consumes less electricity than a normal induction fan. It’s also called an energy-saving fan or brushless DC fan. Let us go over this in greater detail.
A BLDC fan is meant for use with a BLDC motor in a ceiling fan called a BLDC fan. A BLDC motor effectively uses 90% of its flowing current. It consumes less electricity than an induction motor or a regular ceiling fan, saving up to 60% of the power.
Additionally, it is worth noting that, in a BLDC ceiling fan, a DC motor or DC current is used. Though all of the electric appliances in our home run on AC current, the inverter stores it as DC current. So the BLDC fan contains a PCB that converts DC current to AC current, allowing it to be used with an inverter while using the least power.
What is BLDC Fan Technology
As mentioned, a BLDC motor does not have a brush, so it does not generate heat like a regular induction motor or a normal fan. It also has two parts, like a normal fan: the rotor and the stator.
Rotor: A BLDC ceiling fan has a permanent magnet used in the rotor that sticks to the rotor.
Stator: Copper winding is used in the stator, which produces magnetic flux after the electricity supply.
An electric motor has two parts: the rotor and the stator. When the same ends of two magnets touch (south and south, north and north), they push each other and make the rotor move. We must keep changing the magnet ends to keep the rotor moving continuously. An electronic device called a drive, or a PCB in a BLDC fan, does this automatically by changing the magnet ends in the stator; this way, the motor moves continuously.
BLDC Fan vs Normal Fan
BLDC fans are extremely quiet and produce no heat. You may not need to perform routine maintenance as a regular fan. The BLDC fan can be controlled remotely and looks more appealing than a standard fan. You can use a BLDC fan in conjunction with your IOT devices. However, BLDC fans are costly. You could get three standard fans instead of one BLDC fan. However, in terms of long-term use, they are much more energy efficient.

A standard ceiling fan requires regular maintenance, and its coil burns if the voltage fluctuates. A regular ceiling fan cannot be controlled by a remote and is not as smart as a BLDC fan, but it is three times less expensive. Normal ceiling fans consume a lot of power, but BLDC fans are extremely energy efficient.
The disadvantage of a normal ceiling fan
- You can’t make them smart because it is just an electrical fan.
- Regular ceiling fans consume a lot of power, so they could be more energy efficient.
- They heated much, and overheating can burn the copper coil and interior windings.
- You can’t make a regular fan an IOT-enabled or smart fan.
Advantages and disadvantages of a BLDC ceiling fan or motor.
Pros:
- Less overall maintenance due to the absence of brushes.
- Low noise due to the absence of brushes.
- Higher speed range and lower electric noise generation.
- Long lifespan without maintenance.
- It has no mechanical commutator and associated problems.
- High efficiency and high output power-to-size ratio due to using a permanent magnet rotor.
- Smaller motor geometry and lighter in weight.
- Less electromagnetic interference.
Cons:
- These BLDC fans are so expensive.
- The electronic controller or PCB required to control this motor is expensive.
- Requires complex drive circuitry.
- Need of additional sensors.
