WebThree-phase current I (A) is equal to 1000 times of real power divided by the 3 times of multiplication of voltage between the line to neutral and power factor. I(A) = 1000 × P(kW) / (3 × PF × VL-N (V) ) While considering the line to line voltage, it will become I(A) = 1000 × P(kW) / ( √ 3 × PF × VL-L (V) ) Let us take a simple example. WebAug 8, 2024 · Three Phase AC Motor FLA (Amperes) = (P [kW] × 1000) / (V × 1.732 × cos ϕ) What percentage of FLA should a motor run? Most electric motors are designed to run at 50% to 100% of rated load. Maximum efficiency is usually near 75% of rated load. Thus, a 10-horsepower (hp) motor has an acceptable load range of 5 to 10 hp; peak efficiency …
