 # Quick Answer: How Much Electricity Does A 3/4 Hp Motor Use?

## 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 many kW is a 20 hp motor?

There is also metric horsepower which has been used in Europe since the beginning of the 19th century. It is equivalent to roughly 735.5 watts….Hp to kW Conversion Table.HorsepowerKilowattsRounded Kilowatts10 hp7.45699872 kW7 kW15 hp11.18549808 kW11 kW20 hp14.91399744 kW15 kW25 hp18.6424968 kW19 kW16 more rows

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

Our 1 hp example pump uses 1.75 Kw per hour; whereas a 2 hp motor of the same type (UST1202) would draw 2.4 Kw per hour. That’s around 24 kWh per day, or around 720 kWh per month, just running only 10 hors per day. During the heat of the summer, many pumps need to run longer to maintain clear water.

## How many amps does a 1 HP 3 phase motor draw?

## How much electricity does a 1 hp motor use?

Here, we have a 1 HP motor. So, 1 HP for 24 hour = 746×24= 17904 Watt-hour which is equal to 17904/1000= 17.904 units. Hence, 17.904 units of Power will be consumed by the 1 HP motor when run continuously for 24 hours.

## How much power does a 3 HP motor use?

## 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 is motor RPM calculated?

RPM = (120 * Frequency) / # of poles in the motor….By formula:((Synchronous Speed – Rated Full Load Speed) / (Synchronous Speed)) * 100% = Slip Rating.((1800RPM-1750RPM) / 1800RPM) * 100%= (50RPM/ 1800RPM) * 100%(50RPM/ 1800RPM) * 100%= . 027 * 100%. 027 * 100% = 2.7%Slip Rating = 2.7%

## How long can an electric motor run continuously?

You should anticipate, given proper attendance, that the motor can run continuously for the life of its brushes, which should be in the range of six months to a year.

## How much electricity does a motor use?

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 do you calculate the power consumption of a 3 phase motor?

Calculate three-phase motor power consumption by multiplying amps by volts by the square root of three (W = AV(sqrt 3). For example, if the motor is drawing 30 amps at 250 volts, you have 30 x 250 x sqrt 3 (about 1.73) = 12,975 watts).
