Do BLDC fans run hassle-free for years?

Posted by Anemos Lifestyle Pvt. Ltd. on

BLDC motors/fans are the new revolutions in the fan industry. It is only a matter of time before smart super-efficient BLDC fans replace all old inefficient induction motor fans. In today’s energy-efficient world, BLDC fans are a hit as these fans are of the type that consumes lower electricity than normal induction fans and thus are also called energy-saving fans. Using a BLDC motor in the ceiling fan, we can save 60% electricity on the ceiling fan. Moving forward, the complete sort of BLDC is Brushless DC.

BLDC fans are fans with a BLDC motor. For a BLDC motor, no brush is used between the rotor and the stator for transferring electricity supply hence called ‘Brushless DC motor’.

Discover the BLDC ceiling fan technology and how BLDC fan works:


BLDC Motor:


Rotor: In BLDC ceiling fans permanent magnet has been used in the rotor.

Stator: Copper winding is used in the stator, which produces magnetic flux after the supply of electricity.

When two same polarities (Eg. S & S, N & N) take place on the rotor and stator, magnetic force pushes the rotor to a rotational movement. For the continuous rotation in the rotor, we have to change polarity in the stator, so each time the same polarity takes place on the rotor and stator, that helps to continuous rotation in the rotor. An electronic drive is used for continuous changes in polarities in the stator

BLDC Drive:

In the BLDC Drive, the following main components are used.

SMPS: SMPS is used for converting AC supply into DC supply.

Microcontroller: A microcontroller receives the input data from the remote control and gives output data accordingly to the inverter.

Inverter: After receiving a signal from the Microcontroller, the inverter drives to the motor.



BLDC technology has been within the marketplace for a few years now, and it's widely utilized in industries where high torque motors are required. What was missing to date was its application in ceiling fans. But this is often rapidly changing as of today.

Normal Ceiling Fan Vs BLDC Ceiling Fan


The lifespan of BLDC fans is longer as compared to that of a normal ceiling fan because there is no heat generated in BLDC Motor, thus increasing the lifespan of ceiling fan bearings; also, there are fewer chances for winding failure thanks to the utilization of high thickness copper wire within the winding.

The main difference between ordinary DC and BLDC fans is the commutation method used by the motor. Commutation is a technique of changing the direction of current in the motor for rotational movement. In a BLDC motor, as there are no brushes, the driving algorithm completes the commutation within the Electronics.

The main advantage is that the commutators can undergo wear and tear over some time due to mechanical contact during a brushed motor; this is eliminated in BLDC Motor, making the motor more rugged for long-term use. BLDC Motors generate less heat than the normal induction motors and operate at a wide Voltage rating (say 140Vac-265Vac) at a stable speed. Due to these differences in BLDC motors, the BLDC fans run hassle-free for years.

Some manufacturers give 5 years warranty on BLDC motors, whereas induction motor manufacturers give only a year or two.
