## How many amps is my 7.5 hp motor?

How to Convert Horsepower to Amps

1. Amps = (Horsepower × 746) ÷ Efficiency ÷ Volts.
2. Watts = Horsepower × 746.
3. Watts = Wattsη
4. Amps = Watts ÷ Volts.
5. Amps = HP × 746V × η × PF.

## How much power is needed to run a motor?

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 is at 7.5 hp. A motor’s efficiency tends to decrease dramatically below about 50% load.

## How many amps does a 1.5 HP 220v motor draw?

The 1.5 HP Baldor motor that turns at 1725 will draw 18 amps according to its name plate.

## How do you find the amperage of 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.
