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.
Is kW same as HP?
Please provide values below to convert kilowatt [kW] to horsepower (metric), or vice versa.

|Kilowatt [kW]||Horsepower (metric)|
|0.1 kW||0.1359621617 horsepower (metric)|
|1 kW||1.3596216173 horsepower (metric)|
Which is bigger kW or HP?
Kilowatt is a unit used in SI (metric) system while horsepower is not a standard unit. Horsepower is not a well-defined unit, but Kilowatt is a well-defined unit. Horsepower has many forms such as break horsepower, metric horsepower, Boiler horsepower etc. Kilowatt only takes one form.
How many kW is a 3hp motor?
Three Phase Motors
How much work can a 2 hp motor do in 1 hour?
So Here, Power = 1/2 H.P or 373 Watts or 0.373 kilo Watts. Time = 1 Hours.
How much power does a 2 hp motor use?
How many watts does a 2 HP motors have? If a 2 horse power motor is doing 2 horsepower of work then in the load about 1500 Watts of energy is used in the load.
