## How many kiloWatts does a 50 hp motor use?

So — 37,300 Watts / 0.92 = ~ 40,500 Watts is required to be input to the motor to get the 50 HP output. In terms of kiloWatts (kW), — the terms that your electric company charges you — this is approximately **40.5 kW**.

## How much power does a 1hp motor use?

When the 1 HP motor is running continuously for 24 hours, **17.904 units** of Power will be consumed.

## How much electricity does a 1 horsepower motor use?

The 1 HP motor consumes **746 Watts** regardless of how many hours it is running. Watt and HP are not units of energy. It will consume in 1 hour. 746 KWH of energy.

## How do I calculate power?

**Power is equal to work divided by time**. In this example, P = 9000 J /60 s = 150 W . You can also use our power calculator to find work – simply insert the values of power and time.

## How much power does a motor use?

Calculate the power the motor consumes while in operation. The equation is **W = AV(sqrt 3)** where A is amperes, V is volts, and sqrt 3 is the square root of 33 (about 1.73). W is the power consumption in watts. For example, if the electric motor uses 50 amps at 240 volts, the wattage is 50 x 240 x 1.73, or 20,760 watts.

## How do you calculate the power of a motor?

**Power = (Force x Distance) / Time**

For electric motors, power or horsepower can be calculated from the torque and speed. For example, if you have a motor rated for 3,000 RPM and 6 in-lbf then the horsepower is calculated below.
