This calculator estimates the crucial full load amps (FLA) your motor will draw at its rated horsepower. Enter the motor’s voltage (line-to-line voltage between any two phases) and horsepower. For a more precise calculation, include the motor’s efficiency (typically 90-95%).
14 mar 2016 · Three Phase Load Calculating kVA and kW (Three Phase) Formula: kVA = V x I x √3 ÷ 1000 Where: V = Volts generated I = Amps available P.F. - Power factor of load (Usually 0.8) √3 = 1.732. To calculate the current (Amps) I = kVA x 1000 ÷ V x √3. three-phase-load-calculator.xls (770 KB)
You can use this example to see how the 3-phase power calculator works: A 100 amps motor on a 240V 3-phase circuit with a 0.9 power factor produces 37.41 kW of electrical power. Insert these 3 quantities in the calculator, and you should get the same result.
