When you talk of power savings, the first appliances that people try to curtail the use of are the ACs and refrigerators. However, do you know that your ceiling fan can consume more power than the fridge?
The regular ceiling fans are the second highest power consumer after the AC. However, you can reduce the electricity consumption of the ceiling fans by switching over to the BEE 5-star rated ceiling fans.
Going one step further and using the fans with the BLDC motors can help you conserve more power than the regular fans.
What are BLDC motors? How are they useful?
The advantages the Brushless motor has over the traditional Brushed motor are as follows.
- High torque to weight ratio
- More torque per watt
- Enhanced reliability
- Reduction in noise
- Longer lifespan
The housing supports the windings in the BLDC motor. It explains why you can cool the motor by conduction. It does not require any airflow for the internal cooling thereby implying that the motor parts have full protection from dirt and other foreign matter. The Super-Efficient fans of today use these BLDC motors instead of the traditional ones.
Atomberg Technologies used these BLDC motors to manufacture the Gorilla Fans, the Super-Efficient fans. These motors help to reduce your electricity consumption by an average of 65% per month.
Normal Fans vs. BLDC Fans
This table should help you understand the difference between the traditional fans and the ones with the BLDC motors.
|The speed of the Fan||BLDC Motor Fans||Traditional Ceiling Fans|
|1||6 Watts||16 Watts|
|2||10 Watts||27 Watts|
|3||14 Watts||45 Watts|
|4||19 Watts||55 Watts|
|5||28 Watts||75 Watts|
Thus you can see that the BLDC motor fans consume less power as compared to the traditional ceiling fans. We shall now translate these power savings in absolute terms to understand how the BLDC fans can save you money in the long run.
The fans run for about 15 hours a day on an average. With this assumption let us compare the economics of the regular fans and the BLDC motor fans.
|Regular Fan||BLDC Motor Fan|
|Approximate Cost||₹ 1600||₹ 3300|
|Consumption of power||75 Watts||28 Watts|
|Hourly Consumption||0.075 units||0.028 units|
|Daily Consumption||1.125 units||0.42 units|
|Yearly Consumption||410.625 units||153.30 units|
|Costs (₹ 6 per unit)||₹ 2463.75||₹ 919.80|
This table shows that you recover the difference in the cost of the two fans within two years (within the first 15 months).
Other than the savings in consumption of electricity, you have additional benefits to the BLDC Motor fans.
Thus, we have seen that the BLDC motor fans are extremely energy efficient.
