WebJan 23, 2024 · 3 phase motor amps calculation. If we know the watts rating and efficiency of the motor then we can calculate the amperage of the motor or current rating of the … WebAug 16, 2024 · Amps = HP × 746 V × η × PF. Thus, the current in amps is equal to horsepower times 746 divided by the voltage times the efficiency η times the power factor. For example, let’s find the current draw in amps of a 1 horsepower motor that runs at 120 volts with a 90% efficiency. Amps = 1 HP × 746 W 120 V × .9. Amps = 746 120 V × .9. nene by manomano chord and lyric
