How much power does a 30 hp motor use?

Designed power capacity of a motor 30 HP,at 415 V, 3 phase power factor 0.8 (assumed). Full load current is , one HP is 745 w, 30 HP is 30 x 745 =23.35 kW, W = V x I x pf, 23.35 = 415 x I x 0.8, I = 23.35 divided by 415 x 0.8 = 67 amps.

How much electricity does a 25 hp motor use?

Getting back to the question 25 horse power ideal motor consumes around (746*25 = 18650) Watts in an hour. Or around 18.65 Kw of energy.

How much electricity does a 20 hp motor use?

If the motor actually delivers 20 horsepower (hp) of mechanical power, then the motor will draw 49 amps.

How many kwh does a 50 hp motor use?

So — 37,300 Watts / 0.92 = ~ 40,500 Watts is required to be input to the motor to get the 50 HP output. In terms of kiloWatts (kW), — the terms that your electric company charges you — this is approximately 40.5 kW.

How much electricity do motors use?

The annual energy cost of running a motor is usually many times greater than its initial purchase price. For example, even at the relatively low energy rate of $0.04/kWh, a typical 20-horsepower (hp) continuously running motor uses almost $6,000 worth of electricity annually, about six times its initial purchase price.

How much electricity does a 1.5 hp motor use?

1.5 hp = 1 kw =0.3 kwh for 20 minutes per day. Thus the energy required per day is = 1.119/3 = 0.373 kWh.

How do you calculate power consumption of a motor per hour?

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 do I calculate power?

Power is equal to work divided by time. In this example, P = 9000 J /60 s = 150 W . You can also use our power calculator to find work – simply insert the values of power and time.

How do you calculate the power consumption of a single phase motor?

Single-Phase Calculations

Basic electrical theory tells us that for a single-phase system, kW = (V × I × PF) ÷ 1,000. kW = (V × I) ÷ 1,000.

How much power does a 10 hp motor consume?

There 746 watts for every 1 horse power. So a 10 hp motor will need 7680 watts when operating. In one hour the motor will consume 7.680 KWatt hours. If the units are charged at 10 cents each then then that equates to 10x 7.680 / 100 Dollars = 76.8 cents.

How much electricity does a 2hp motor use?

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. Two horse powers are approximately equal to 1,5 kW. That means if you run that pump for one hour it’ll use 1,5 kWh of energy.

How many watts does a 220 well pump use?

Consumer reports says a well pump runs about 700 watts. Multiply that by 3 to get a rough estimate of the starting wattage for the pump and you run about 2100 which still leaves plenty of wiggle room in terms of wattage.

How much power does a 2 hp motor use in one hour?

1 HP = 745 Watts, So 1/2 HP = 372 Watts . Current consumption at 220 V would be 1.7 Amps. In one hour -0.372 kWh (Units).
