Fans are an integral part of most of the Indian households, running for hours, without any notice. Most of us do not even realize that ceiling fans consume more electricity than a refrigerator in a house. In fact, after air conditioners, it is the second biggest contributor to electricity bills in any household.
When we are switching to LED lights, Solar inverter and so many other green and clean source of energy while thinking of reducing the electricity bill, surprisingly ceiling fans are the most ignored appliance.
Now, since we know, ever thought of reducing power on ceiling fans consumed using a technology called Brushless DC Motor or simply BLDC motor?
Normal Fans runs with an induction motor and BLDC fans operate with BLDC motor. An induction motor uses a series of coils powered by AC input voltage to create magnetic fields in the stator (static part) and induce magnetic field in the rotor (rotating part).
A BLDC fan composes of three main components -stator, rotor and shaft. BLDC motors, permanent magnets are the rotor which creates a magnetic field and the electromagnets are on the stator. A commuter then charges the electromagnets in the stator to rotate the rotor a full 360-degrees.
Due to sensor less electronic control and frictionless commutation, BLDC fans produce less heat with higher efficiency.
BLDC fan lifespan is more than a normal ceiling fan because there is no heat generated in BLDC Motor increasing the lifespan of ceiling fan bearings, reducing the chances of the winding failure because of the usage of high thickness copper wire.
BLDC fans are better! Know how?
- Lower Electricity Consumption (70% savings)
- Longer backup on any Inverters, both solar as well as regular.
- Improved reliability.
- Quiet and Noiseless.
- Longer lifetime.
- These fans come with a remote-control unit. Switch on and off the fans easily from your comfort zone.
- These BLDC motor fans also have timer and sleep mode. So, you decide for how long you want it to run.
- The technology also has the facility to reduce the speed of the fan gradually after the set time. Less speed, hence less electricity consumption. Saves the pain of getting up at night to control the regulators.
Intelizon is one among those brands who have started retailing fans equipped with BLDC motors. In India, where electricity is still a major problem in most of the parts, switching to BLDC fans is one the brightest idea to combat the challenges of huge power consumption.
As per some theory, replacing the AC motors with BLDC motors can reduce energy consumption by about 40 million kilowatt hours (kWh), which is huge. BLDC motors are smaller, more energy efficient and have better speed control than the age-old traditional fans, still most of the household have their appliances run AC motors.
IIT Bombay has already replaced 3000 induction fans with BLDC fans. When are we going to replace our living and bedroom ceiling fans with BLDC fans?
