Mr. Sanjeev Pandey is a first generation entrepreneur who started his career with USHA fans in 1995. Since then he has served for almost all the major brands in Kolkata like KHAITAN ELECTRICALS, POLAR INDUSTRIES, ORIENT ELECTRIC,BAJAJ FANS etc. He understood that saving electricity is what every consumer is looking for and no one is making energy efficient ceiling fans. After a log of research in Mumbai for last 3 years he has developed a BLDC ceiling fan. A brushless DC (BLDC) motor is a synchronous electric Motor powered by direct-current (DC) electricity and having an electronic commutation system, rather than a mechanical commutator and brushes. In BLDC motors, current to torque and voltage to rpm are linear relationships. This linearity provides an excellent opportunity to use the BLDC motor in the conventional ceiling fans. This paper presents practical implementation of such BLDC motor for ceiling fan application along with the actual power measurements in comparison with conventional ceiling fans.
