The common ceiling fans that are available in the market use single phase induction motors, which are inexpensive but extremely inefficient. It is estimated that there are over 400 million ceiling fans in India, and when all these fans operate at medium speed (39W) for 7 hours a day, there is an electricity consumption of over 95500MU every day. This creates a huge pressure on the country’s electric grid, economy and the environment. Despite this high demand and the lack of efficiency, there were no significant changes to the core design of ceiling fans for decades.
Super fans are designed to address issues beyond efficiency such as speed fluctuations due to voltage fluctuations, inoperativeness in low voltages, capacitor failure, motor winding burning, overheating and lack of remote operation. In 2012, first Superfan model was released that consumed only 35 W while delivering same or better air delivery and increased functionality than regular fans which consume 75W. Subsequently other super energy efficient ceiling fan models with additional features that cater to different needs were released. Our innovative approach to BLDC ceiling fans has been recognized with a design patent.
