The new Super Efficient Fan use a different type of electronic motor, which is also called Brushless DC (BLDC) motor. This new technology with efficient blade designs makes ceiling fans far more efficient, and the fans consume 30-35 Watts of electricity, which is about 50% less than the old regular fans. Some of such ceiling fans have air delivery of 220-230 m3/min that makes them almost the same in performance as compared to the regular ceiling fans.
As per BEE specifications, these changes should allow super efficient fans to give:
a.None or very low degradation in performance at lower voltages;
b.Reliable even under high ambient temperature;
