BLDC motors have an advantage where they can spin at varying speeds. Hence, they consume less electricity than those appliances fitted with conventional motors.
Let us look at the BLDC fan versus normal fan power consumption to understand the concept better.
You can use our ceiling fan power consumption calculator to know the consumption figures. The calculation requires you to input the following data.
- The rated power of the ceiling fan
- The average daily usage
- The electricity tariff in your area
Let us consider the consumption figures of two normal fans and BLDC fans.
|Parameters||Crompton Super Briz Deco 1200mm||Usha Striker Galaxy 1200mm||Usha Heleous 1220mm Premium BLDC Ceiling Fan||Atomberg Renesa 1200mm BLDC Ceiling fan|
|Rated Power in Watts||70||80||43||28|
|Daily usage in hours||10||10||10||10|
|Electricity Tariff in Rs||7||7||7||7|
|Daily consumption in units||0.7||0.8||0.43||0.28|
|Monthly consumption in units||21||24||12.9||8.4|
|Annual consumption in units||252||288||154.8||100.8|
|Monthly electricity bill component in Rs||147||168||90.3||58.8|
From the above power consumption calculations, we can see that the BLDC fans consume far less power than the regular ceiling fans. Admittedly, the BLDC motor fans are expensive, but one can comfortably recover the cost within a year or two.
