What is BLDC Technology and How Does It Save Up to 65% Electricity?
BLDC stands for Brushless Direct Current. Traditional ceiling fans use AC induction motors with heavy copper windings and mechanical friction, wasting energy as heat. BLDC fans use permanent neodymium magnets and an electronic inverter driver board, reducing power draw from 75 Watts down to 28 Watts at maximum speed.
Benchmark Energy Comparison (16 Hours/Day for 1 Year):
- 28W 5-Star BLDC Fan (Atomberg / Orient / Havells):
Annual Energy: (28W × 16 hrs × 365) ÷ 1,000 = 163.5 Units / year. - 75W Conventional Induction Ceiling Fan:
Annual Energy: (75W × 16 hrs × 365) ÷ 1,000 = 438.0 Units / year. - Annual Units Saved: 438.0 - 163.5 = 274.5 Units / year per fan (~62.6% energy reduction).
