# Best answer: How do you calculate motor horsepower?

Contents

The quickest method to closely estimate motor horsepower is to use a digital clamp meter to measure current and voltage to the motor, and then perform a simple calculation. Use this formula to estimate motor horsepower. Horsepower(hp)= Voltage x Amperage x % EFF x power factor x 1.73/746.

## What is the current for 1 hp motor?

## How many horsepower is a 1000 watt motor?

Watts to horsepower conversion table

Watts (W) Mechanic horsepower (hp(I)) Metric horsepower (hp(M))
700 W 0.938715 hp 0.951735 hp
800 W 1.072817 hp 1.087697 hp
900 W 1.206920 hp 1.223659 hp
1000 W 1.341022 hp 1.359622 hp

## How do you identify motor power?

By taking the voltage and multiplying it by the associated current, the power can be determined. A watt (W) is a unit of power defined as one Joule per second. For a DC source the calculation is simply the voltage times the current: W = V x A.

## How do you find the KW of a motor?

Multiply the motor voltage by the full-load current. The result is in watts. Divide watts by 1,000 to give kilowatts. For example, 230 volts x 20 amps = 4,600 watts; 4,600 watts divided by 1000 = 4.6 kilowatts.
