How much electricity does a 1 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 much electricity does a 1 hp pump use?

A 1 hp sump pump SHOULD draw about 750 watts running and about 15-1800 starting. Also know, how many watts does a water pump use? A typical water pump’s wattage can vary between 250 watts to 1,100 watts.

How much does it cost to run a 1 hp motor?

Our 1 hp (standard) example UST1102 motor above will cost between $1-$5 per day, depending on what your power company charges per kWh, and on how many hours per day the pump is running, which changes within the season. This will result in a monthly cost of $30-$150.

How do you calculate the power consumption of a single phase motor?

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 many units of electricity will be consumed if we run a 1 HP 3 phase motor for 24 hours?

Electrical Input Power = (Output Power/Efficiency). Assuming 90% efficiency, Input Power = 0.746/0.9 = 0.83kW. So, the consumed units of electricity = Power in kW X numbers of hours of operation = 0.83 units (assuming the motor is running for an hour).

How much power does a 2 hp motor use?

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 much does it cost to run a 100 hp electric motor?

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 power 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.

How much power does a 1.5 HP pool pump use?

It’s not uncommon for a 1.5 horsepower pump to use 1500 – 2000 watts. This is unfortunate, because most pools only need 1/4 to 1/8th horsepower for circulation. Higher power may be needed for tasks like vacuuming the pool.

What is the formula for power consumption?

The first step in calculating your energy consumption is to figure out how many watts each device uses per day. Just multiply your appliance’s wattage by the number of hours you use it in a day. This will give you the number of watt-hours consumed each day.

How many kW is an amp?

How do you calculate motor kW?

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 much power does a 7.5 hp motor consume?

Let us assume that motor is operating at full load so it will consume 7.5 hp or 5.59 or 5.6 kW approx. Let us assume motor has efficiency of 90 %, motor at full load gives around 90 % efficiency, so the power input to motor is 5.6/0.9=6.22 kW. Energy consumption in 2 hrs = 6.22×2=12.44 KWh or 12.44 unit.

How do I calculate unit per hour?

If you use 1000 Watts or 1 Kilowatt of power for 1 hour then you consume 1 unit or 1 Kilowatt-Hour (kWh) of electricity. So the reading on the electricity meter represents the actual electricity used.
