Question: How Much Power Does A Motor Use?

How much power does a 7.5 hp motor consume?

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 is motor horsepower calculated?

Horsepower (hp) = voltage x amperage x % EFF x power factor x 1.73/746.Voltage is the average of the three voltages measured: (A-B + A-C + B-C)/3.Amperage is the average current of the three-phase measured: (A+B+C)/3.% EFF is motor efficiency per motor nameplate.More items…

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 many units of electricity will be consumed if we run a 1 HP 3 phase motor for 24 hours?

59.76 unitsUnit consumed = Power in kW X numbers of hours of operation. = 59.76 units. Hence units burnt (consumed) by 3 HP motor in 24 hours will be 59.76, if the motor efficiency is 90% and motor is fully loaded. In actual, motor load will be less than full load and units consumed will be less accordingly.

How much power does a 3 HP motor use?

How much electricity does a gate motor use?

In standby, an electric gate system will use about 100 watts per day. With electricity costing around 15p per KWh this translates to 1.5p per day.

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 1 hp motor consume?

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 2 hp motor consume?

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 many kW is a 20 hp motor?

In those countries where the Imperial system is practiced, mechanical or imperial horsepower is used, which is approximately equal to 745.7 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
