# Quick Answer: How Much Power Does An Electric Motor Use?

## How many amps are in a horsepower?

For example, an engine at two horsepower with 230 volts would be calculated as two horsepower times 746 watts, which equals 1492.

Divide the number calculated in Step 1 by the amount of volts to calculate watts.

In the example, 1492 would be divided by 230, which equals about 6.49 amps.

Check the calculations..

## Why is 1hp equal to 746 watts?

The term ‘Horse Power’ was defined in 18th century around the time when steam engine was invented. Power of engines was compared with capacity of a horse, and the term Horse Power came into use. The base unit HP is defined as 550 Foot- Pound per second. Its equivalent in metric system is 746 Watts (0.746 KW).

## 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.

## What is absorbed power of a motor?

Absorbed power is the expected power drawn by the load. Most loads does not operate at its rated capacity, but at lower point. The motor is typically sized so that the rated capacity of the motor exceeds the expected absorbed load by some conservative design margin.

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

Single-Phase Motors – HP and Full-Load CurrentsPowerFull Load Current (amp)(hp)(kW)208 V21.513.232.318.753.830.87 more rows

## How much electricity does a 30 hp motor use?

Total power consumption of the motor will be W =root 3 ×VL ×IL ×PF. That will be 1.732 ×415 ×25 ×0. 8 =14360 watts and it will be 14360 ÷1000 =14.36 kW, and motor was run for a period of 1 hour, so it will be 14.36 ×1 =14.36 kwh.

## How much does a electric motor cost?

Industrial electric motors can cost anywhere from a few hundred dollars to hundreds of thousands of dollars. Generally the size rating (Horsepower, Kilowatt, Megawatt, etc.) as well as the speed (RPM or Revolutions Per Minute), Input Voltage, and frame size all factor into the price.

## How much electricity does a 2 hp motor use?

So coming to your question, if you are running the pump for one hour then your motor would have consumed 1.49KW × 1hr = 1.49 KWh. If it is for 2 hours, then 1.49KW × 2hr = 2.98 KWh. This is how the energy( KWh)consumed by the motor is determined.

## How do you calculate the power of a 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 much electricity does a water motor use?

A typical water pump’s wattage can vary between 250 watts to 1,100 watts. Take the wattage of the specific water pump and multiply it times how many hours a day it runs. Then, multiply it by how many days a year it runs, and divide by 1000. This will give the amount of kilowatt-hours the pump is using.

## How much electricity does a 5 hp motor consume?

If this motor is delivering 5 H.P. of power then electrical power it consumes is equal to 5 H.P. + Power loss in motor. Energy consumed = 5 H.P. × 1 hour = 5 H.P. hour = 5 × 746 Watts hour = 3730 Watts hour ( I did this multiplication in mind, If it’s right then yayyy!) Peace.

## 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 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.
