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

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 energy consumption 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 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 3 HP motor use?

If the motor is fully loaded, it will provide output power of 3HP = (3 X 0.746) kW = 2.24 kW. Electrical input power = output power / (Efficiency /100). Unit consumed = Power in kW X numbers of hours of operation. = 59.76 units.

How much power does a 1.5 hp motor use?

So, 1.5 HP= 1119W=1.119KW or lets say 1.12 KW. So, we see power consumed by motor is 1.12 Kilo Watts. But, we pay for energy consumed by us measured by Energy meter.

How much electricity does a 5 hp motor consume?

Therefore, the power consumed by a 5 HP motor performing at 80% efficiency will be: 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 power does a motor consume?

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).

How many kW is equal to 1 unit?

A unit (as mentioned on the electricity bills) is represented in kWH or Kilowatt Hour. This is the actual electricity or energy used. If you use 1000 Watts or 1 Kilowatt of power for 1 hour then you consume 1 unit or 1 Kilowatt-Hour (kWH) of electricity.

How much electricity does a 20 hp motor use?

Measure all three phase-to-phase voltages, and average them.

In our 20 hp motor example, let’s say we measure 226, 230 and 234 volts, giving an average of 230 volts.

What is the difference between HP and kW?

Obviously, a kilowatt is 1,000 watts. To convert kilowatts to horsepower, we multiply the number of kilowatts by 1.34. The result is that 80 kilowatts is roughly equivalent to 107 horsepower.

Is 1hp equal to 1 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.

How much is 1 kW?

One kWh represents the amount of energy needed by a 1000-Watt device (such as a clothes iron or a microwave oven) to operate continuously for one hour. The US Energy Information Administration reports that, on average, a kilowatt-hour costs about $. 13 USD across the country.

How do I convert HP to kWh?

Multiply the number of horsepower by the time the power is exerted. For example, if you have a 20-horsepower motor running for three hours, you would multiply 20 by 3 to get 60 horsepower-hours. Multiply the number of horsepower-hours by 0.7457 kilowatts per horsepower-hour to convert to kilowatt-hours.

How much power does a 50 hp electric motor use?

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 do you calculate the current of a 3 phase motor?

Use the Ohm’s law formula: Power (watts) = Voltage (volts) x I current (amps). Arrange the equation for three-phase power to solve the current (amps): Current (amps) = power (watts) ÷ voltage (volts) ÷ square root of 3 (1.732) ÷ power factor; I = P ÷ (V_1.
