If you are planning to buy a new fan or upgrade your old ones, the bldc vs normal fan comparison becomes essential. This article will dive deep into how these two types of fans work, their advantages and disadvantages, and which one offers better value for money.
Understanding Normal Fans
Normal fans, also known as AC induction motor fans, have been around for decades. They are affordable, durable, and widely available across urban and rural markets.
How Normal Fans Work
- A normal fan runs on a single-phase AC induction motor.
- The stator produces a rotating magnetic field when electricity passes through copper windings.
- This induces current in the rotor, causing it to spin and rotate the blades.
- The speed of the fan is controlled by a regulator, which reduces voltage to slow down rotation.
Characteristics of Normal Fans
- Power Consumption: Around 70–80 watts at full speed.
- Speed: 300–400 RPM depending on the design.
- Cost: Typically between ₹1,200 and ₹2,500 in India.

Understanding BLDC Fans
BLDC fans use Brushless Direct Current motors and electronic controllers. Unlike induction motors, they don’t rely on brushes and commutators for current switching. Instead, permanent magnets and smart electronics handle the process.
How BLDC Fans Work
- The AC supply is converted into DC using an electronic driver circuit.
- Permanent magnets on the rotor interact with the electronically controlled stator field to rotate smoothly.
- Since there are no brushes, friction is minimal, leading to higher efficiency.
Characteristics of BLDC Fans
- Power Consumption: Only 28–35 watts at full speed.
- Speed: Around 300–380 RPM, stable even at low voltages.
