How is fan motor power calculated?
Divide the fan’s power consumption, measured in kilowatts, by 0.746 to convert it to horsepower. If, for instance, a fan consumes 4 kW: 4 / 0.746 = 5.36 horsepower. Multiply the result by the fan’s efficiency. If the fan operates, for instance, at 80 percent efficiency: 5.36 x 0.80 = 4.29 horsepower.
