Amperage will fluctuate depending on several factors. These factors include but are not limited to input voltage, motor rpm, and motor brand. For example a 1.5 HP Baldor motor turning 3450 rpm draws 13.4 amps on 120 volt service.

## How many amps does a 1.5 hp motor use?

Watts = Watts ÷ Efficiency. Amps = Watts ÷ Volts. Amps = (HP × 746) ÷ Efficiency ÷ V.

---|---|---|

1.5 HP | 10.4 A |
120 V |

## How many amps does a 0.5 hp pump draw?

**0.5hp is** 373W, so @ 220V thats 1.7**amps** secondary side, primary side **will** be at least double that approx 3.5**amps**.

## How do I convert hp to amps?

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.
