20 HP is 14.9 Kilowatts. We might suppose that the motor is 90% efficient, which makes the required input power about 16.5 KW. In 24 hours, that would use 397 kilowatt hours, costing $47 per day or so.
How much does it cost to run a 25 hp motor?
Re: Cost to operate a 25 HP Motor…
08 = $1.488 per hour.
How is motor running cost 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 does it cost to run an 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 does it cost to run a 1hp 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 much electricity does a 7.5 hp motor use?
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 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.
How much electricity does a 5 hp motor consume?
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 electricity is consumed if I run a 1 hp motor in 3 phase for 1 hour?
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 electricity does a 10 hp motor consume?
So a 10 hp motor will need 7680 watts when operating. In one hour the motor will consume 7.680 KWatt hours. If the units are charged at 10 cents each then then that equates to 10x 7.680 / 100 Dollars = 76.8 cents.
How many watts does a 25 hp motor use?
Re: how much electricity or units does it consumes,if a 25hp. motor runs for an h. One horsepower = 746 Watts. So 25 hp = 18,650 Watts.
How do you calculate the power consumption of a single phase motor?
Single phase power equations:
- Real Power. Wapplied = U I PF / 1000 (1) where. Wapplied = real power (kilowatts, kW) U = voltage (volts, V) I = current (amps, A) PF = power factor – 0.7 – 0.95.
- Total Power. W = U I / 1000 (2)
- Brake Horsepower. WBHP = U I PF μ / 746 (3) where. WBHP = brake horsepower (hp) μ = device efficiency.
How many units does a 1 hp motor consume?
17904 Watt-hour is equal to 17904/1000 units and 1 HP for 24 hours is 746 24. When the 1 HP motor is running continuously for 24 hours, 17.904 units of Power will be consumed.
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.
Does pool pump use a lot of electricity?
So, if you run your pool pump for 8 hours in one day, 1,864.25 multiplied by 8 and divided by 1,000 equals 14.9 kilowatt-hours. If you run your pump every day for an average of 30 days per month — 30 multiplied by 14.9 — your pump uses 447 kilowatt-hours in a month.
How many amps does a 1 HP pool pump draw?
Since it’s an aboveground pool pump it’s an uprated model and draws in the vicinity of 10 to 12 Amps at 120 volts.
