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. Electricity costs are based on kilowatts (kW), so divide watts by 1000 to convert to kilowatts (20,760 wats/1000 = 20.76 kW). Record the time the motor is in operation.

How many watts is a 0.5 hp motor?
A 0.5hp motor uses about 380W of power if it is running at 100% rated load. It can use more power than that if it is under load. If it is not under load it will use less than 0.5hp. In one minute it will use Power x 1/60 Watt hours.
How do you calculate kwh 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.
How is motor wattage calculated?
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 much power does a 5 hp motor use?
Therefore, the power consumed by a 5 HP motor performing at 80% efficiency will be: Output mechanical energy: 5 HP X 746 Watts = 3,730 Watts or 3.73 kW. As the output mechanical energy is the result of the motor performing at 80% efficiency, the power consumed by the 5 HP motor will be 3.73 kW X 100 ÷ 80= 4.66 kW.

How many watts does it take to run a drill?
It depends on several factors, but the average cordless drill charges with a battery that needs 25 to 100 watts, whereas most corded drills need 800 to 1,200 watts to operate. The reason that corded drills require so much more is that they draw a constant current.

How many watts does a pressure pump use?
Energy usage of pumps
The energy consumption of pumps increases as the pumps get more powerful. For example, pumps rated at about 35L a minute use about 600 watts when they are pumping, while pumps rated at 45L a minute can consume about 800 watts.
How do I convert kW to units?
Just like the odometer on your vehicle that shows the actual distance travelled by the vehicle, electricity meter shows the amount of electricity that is used. So a 100-Watt bulb if kept on for 10 hours will consume: 100 x 10 = 1000 Watt-Hour = 1 Kilowatt-Hour (kWH) = 1 units (on your meter).
How much power does a 100 hp motor use?
This 100-horsepower centrifugal pump motor, if fully loaded, should be consuming nearly 80,000 watts (80 kW).
