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. Quite similarly, a higher power factor is proportional to higher power output. You need to input the amps, voltage, and the power factor (it’s between 0 and 1, specific for each circuit):Īs you can see, the more amps and volts you have, the more powerful 3-phase electric motor you have. You can freely use this calculator to convert amps to kW in a 3-phase circuit. 3-Phase Power Calculator: Amps To kW (1st Calculator) That one converts kW to amps in 3-phase circuits, very important in electric motor design. Note: Later on, we will also see how we can use the 3-phase current formula to design a 3-phase motor amps calculator. We can use this equation to design the 1st calculator: 3-phase power calculator (check below). It converts watts into kilowatts because we usually prefer to deal with kW instead of W.īecause we need to use the power factor to calculate the kW from amps, this formula is also known as the ‘3-phase power factor formula’.
