If BLDC motors are implemented in all ceiling fans sold by 2020, 70 Terawatt hours per year could be saved and 25 million metric tons of carbon dioxide equivalent emissions per year could be avoided, globally
LESSER NOISE
Title 3
As BLDCs do not have mechanical contact between the rotors and the brushes, there is minimal noise generated due to its operation.
PRECISE SPEED CONTROL
In BLDC fans, an electronic control circuit is used for speed control. As a result, the speed control is more precise.
Works Better With Inverters
Due to the low electric consumption, BLDC fans run longer on inverter. This is especially helpful during summers when power shortages are frequent.
DISADVANTAGES
HIGH INITIAL COST
Price of BLDC fans typically start from around Rs. 3000 onwards. A normal fan on the other hand costs from Rs. 1200 onwards.
LIMITED TECHNICIANS
BLDC fans have electronic components which makes it imperative to trust only brand service centres for repairs. Installation too should be carried out by professionals with necessary expertise. Else, your fan's performance will not be optimal.
