# Question: How much electricity does a motor use?

Contents

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 do you calculate power consumption of a motor per hour?

Electric Motor power consumption Formula:

The total power consumption E(kWh) is equal to 0.746 times of multiplication of total operating hours t(h) in hour, the rated power P(HP) in HP and the X percentage of the load. Total Power consumption = 0.746 * Horsepower * load percentage * Operating Hours.

## How many units does a 1 HP motor consume?

There is a 1 HP motor here. 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 electricity does a 1/4 HP motor use?

Approximate Running Wattage

Approximate Starting Wattage Approximate Running Wattage
Split Phase 1/3 Horsepower 1950 450
Split Phase 1/2 Horsepower 2600 600
Capacitor Start Induction Run 1/8 Horsepower 850 275
Capacitor Start Induction Run 1/4 Horsepower 1050 400

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

30 HP rating is equivalent to 22.5 KW. Power consumption for 1 hour duration shall be 22.5 KWH. Therefore 22.5 units will get consumed..

## Which motor consumes more electricity AC or DC?

AC motors are generally considered to be more powerful than DC motors because they can generate higher torque by using a more powerful current. However, DC motors are typically more efficient and make better use of their input energy.

## How much electricity does a 10 hp motor use?

10HP = 7460 Watts. This is the output power of the motor. It depends on the load on it. If it is running at full load, it will be 7.46 kWhrs plus around 10% for the efficiency loss so call it 8 kWhrs per hour.

## How many watts does a 25 hp motor use?

25 hp = 18,642.5 Watts according to my calculator.

## 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 many watts does a fridge consume?

Therefore monthly power consumption of my refrigerator is – 460 kWh / 12 – 38.33 kWh of electricity. Hence daily power consumption of my refrigerator is – 38.33 kWh / 30 – 1.278 kWh of electricity. In terms of electricity bill it translates to Rs 12.

## Is 1 HP equal to a horse?

Does one horsepower equal one horse? Not quite. It’s a common misconception that one horsepower is equal to the peak power production of a horse, which is capable of a maximum of around 14.9 horsepower. By comparison, a human being is capable of approximately five horsepower at peak power production.
