How many kW does a 3 phase motor produce?

You can jump to 3-phase amps to kW formula and calculator here. To get an idea of how these calculators work, here is the screenshot of the 3-phase power calculator: Example of how 1st calculator works: A 3-phase motor that draws 90A and runs on a 240V circuit with a 0.8 power factor will produce 29.93 kW of electrical power.

How does a 3-phase power calculator work?

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.

How do you calculate power in a 3-phase AC circuit?

Here’s the 3-phase power equation: P (kW) = (I (Amps) × V (Volts) × PF × 1.732) ÷ 1,000 As we can see, the electrical power in the 3-phase AC circuit depends on: I (Amps): Electrical current, measured in amps. The more amps we have, the more power we have in a three-phase circuit. V (Volts): Electrical potential, measured in volts.

What is the power factor of a 3-phase circuit?

Power factor is defined as a ratio between real power and apparent power. If current and voltage are in phase, the power factor is 1. In the 3-phase circuit, current and voltage are not in phase; thus the power factor will be anywhere between 0 and 1. This accounts for the real/apparent power ratio and is sometimes expressed as RMS current.

How do you calculate 3 phase current?

We get the 3-phase current formula like this: I (Amps) = P (kW) × 1,000 ÷ (V (Volts) × PF × 1.732) Using this power formula, we can, for example, do a 3-phase motor kW to amps calculation. Do note that if a 3-phase motor with lower voltage and lower power factor will draw more amps to produce the same power output.

How many amps are in a 3-phase circuit?

At 1.0 power factor, the amps in 3-phase power in this situation is 28.87 amps. On a 3-phase circuit (with a 0.6 power factor), the 3-phase power calculator shows that the same 6 kW appliance draws 48.11 amps. To see why we get different amperage on a 3-phase circuit, let’s first check how these amps are calculated using the 3-phase power formula:
