How do you calculate amperage for single phase?
Amps calculation with line to line voltage
- I(A) = P(W) / (√3 × PF × VL-L(V) ) So amps are equal to watts divided by square root of 3 times power factor times volts.
- amps = watts / (√3 × PF × volts) or.
- A = W / (√3 × PF × V) Example.
- I = 330W / (√3 × 0.8 × 110V) = 2.165A. Amps calculation with line to neutral voltage.
How do you calculate amps on a motor?
Given horsepower and volts, it is possible to calculate amps. The calculation of amps uses Ohm’s Law, which is amps times volts equals watts. Multiply the horsepower by 746 watts. For example, an engine at two horsepower with 230 volts would be calculated as two horsepower times 746 watts, which equals 1492.
How many amps is a 1 hp motor?
AMP DRAW BASED ON HORSEPOWER
|HP||1 Phase Amps|
|115 volt||230 volt|
How do I convert HP to amps?
How to convert horsepower to amps? Hp to amps formulas
- Single-phase AC. I = P * 746 / (V * PF * η) ;
- Three-phase AC, line-to-line voltage. I = P * 746 / (√3 * V * PF * η) ;
- Three-phase AC, line-to-neutral voltage. I = P * 746 / (3 * V * PF * η) .

How to calculate amps for two phase motor?
Two-phase Amps = [HP * 746] / [E * %age Efficiency * PF * 2] Example: Determine the current flowing through a two-phase, 0.5 HP, 220 volt motor having an efficiency rating of 90% and a power factor of 0.92. Solution: Current = [0.5 * 746] / [220 * 0.88 * 0.9 * 2] = 1.07 Amps
