Three Phase AC Motor FLA (Amperes) = (P [HP] × 746) / (V × 1.732 × cos ϕ × η) Where: P [HP] , P [kW] = Motor power rating (HP or kW), V = Motor rated voltage (Volts), η = Motor efficiency in decimal form, cos ϕ = Motor power factor, 1000 = Conversion factor to convert kW to W, 746 = Conversion factor to convert HP to W.

This calculator will also give you motor amps and recommended breaker size, starter size, heater size and conduit size. Enter the motor horsepower and voltage. Motor HP: ½ ¾ 1 1½ 2 3 5 7½ 10 15 20 25 30 40 50 60 75 100 125 150

10/02/  · How much power does a 20 hp motor use? If the motor actually delivers 20 horsepower (hp) of mechanical power, then the motor will draw 49 amps. How do I know how
