Hammond motor hp to amps chart
WebUse this formula to estimate motor horsepower. Horsepower (hp) = Voltage x Amperage x % EFF x power factor x 1.73/746. Where: Voltage is the average of the three voltages measured: (A-B + A-C + B-C)/3. Amperage is the average current of the three phase measured: (A+B+C)/3 % EFF is motor efficiency per motor nameplate. Power factor is … WebHorsepower (hp) = Voltage x Amperage x % EFF x power factor x 1.73/746. = 472V x 20A x 0.90 x 0.85 x 1.73/746 = 17 Hp. The quickest method to closely estimate motor …
