How do you calculate kwh of a motor?

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).

How many kwh does a 5 hp motor use?

1 Horsepower is equal to 745.7 watts of electrical power, so in theory a 5HP motor operating at 100% efficiency will consume about 3.728kW of power. In one hour, it will use 3728.5 kilowatt-hours.

How do you calculate the kW of a 3 phase 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 do I convert HP to kwh?

Multiply the number of horsepower-hours by 0.7457 kilowatts per horsepower-hour to convert to kilowatt-hours. In this example, you would multiply 60 by 0.7457 to get 44.742 kilowatt-hours.

How many kilowatts does an HP motor run?

746 watts per Hp but, rule of thumb figure 1KW per Hp to allow for efficiency losses. So 10 KWH would run a 10 Hp motor for 1 hour.

How much electricity does a 100 hp motor use?

Expect actual operating costs to vary. For example, a 460-volt, three-phase, standard efficiency 100 HP motor operating under full load for 8,760 hours per year will probably cost just over $48,000 per year to operate at an electric rate of $0.10 per kWh.

How much electricity does a 30 hp motor use?

Designed power capacity of a motor 30 HP,at 415 V, 3 phase power factor 0.8 (assumed). Full load current is , one HP is 745 w, 30 HP is 30 x 745 =23.35 kW, W = V x I x pf, 23.35 = 415 x I x 0.8, I = 23.35 divided by 415 x 0.8 = 67 amps.

What is the 3 phase power formula?

3-Phase Calculations. For 3-phase systems, we use the following equation: kW = (V × I × PF × 1.732) ÷ 1,000.

How many kW is a 10 hp motor?

Which is greater HP or kW?

James Watt is also the reason we have the measurements watt and kilowatt, most commonly used to measure electricity. Obviously, a kilowatt is 1,000 watts. … To convert kilowatts to horsepower, we multiply the number of kilowatts by 1.34. The result is that 80 kilowatts is roughly equivalent to 107 horsepower.
