Question: How Much Does It Cost To Run A 100 Hp Electric Motor?

How do you calculate the power consumption of an electric 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 1 HP pool 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 much power does a 50 hp electric motor use?

For our purposes, assume the motor has an efficiency of 92% ( or 0.92). So divide the output (50 HP) by the efficiency (0.92), to get the energy required to be input into the motor, to get 50 HP. So — 37,300 Watts / 0.92 = ~ 40,500 Watts is required to be input to the motor to get the 50 HP output.

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 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 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 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.
