SUPERFAN – FAN RE ‘INVENTED’
Superfan’s patented original design has brought numerous innovations to a stagnant Indian ceiling fan industry. The following are a select few that shows why Superfan is ‘Fan reinvented’. BLDC Ceiling Fans Super Energy Efficient Ceiling Fan (35 W) Superfan broke the 35W barrier to enable an Indian ceiling fan to enter the super energy-efficient category of appliances. This novel design has been awarded two patents (2873/CHE/2009 and 3505/CHE/2012). Sensor-less BLDC control One of the challenges in BLDC technology was to minimize the failures of hall sensors. Superfan introduced the first ceiling fan in India with no hall sensor for position sensing. This was accomplished by developing a robust back EMF sensing in the firmware. Active Power Factor Correction The SMPS (Switch Mode Power Supply) is integrated with Active Power Factor Correction (APC).[a] Superfan has a power factor of 0.99* while running at the top speed. At the lowest speed (step speed 1), its p
