How much power does a 1 hp motor consume?
1 Horsepower is equal to 745.7 watts of electrical power, so in theory a 5HP motor operating at 100% efficiency will consume about 3.728kW of power. In one hour, it will use 3728.5 kilowatt-hours.
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.
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 much power does a 3 HP motor use?
Single-Phase Motors – HP and Full-Load Currents
|Power||Full Load Current (amp)|
How much does it cost to run a 1 hp electric 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 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 much does it cost to run a 100 hp 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.
What is absorbed power of a motor?
Absorbed power is the expected power drawn by the load. Most loads does not operate at its rated capacity, but at lower point. The motor is typically sized so that the rated capacity of the motor exceeds the expected absorbed load by some conservative design margin.
What is the formula for power consumption?
The first step in calculating your energy consumption is to figure out how many watts each device uses per day. Just multiply your appliance’s wattage by the number of hours you use it in a day. This will give you the number of watt-hours consumed each day.
How do you calculate power consumption?
Just like the odometer on your vehicle that shows the actual distance travelled by the vehicle, electricity meter shows the amount of electricity that is used. So a 100-Watt bulb if kept on for 10 hours will consume: 100 x 10 = 1000 Watt-Hour = 1 Kilowatt-Hour (kWH) = 1 units (on your meter).
How do you calculate the power consumption of a 3 phase motor?
Calculate three-phase motor power consumption by multiplying amps by volts by the square root of three (W = AV(sqrt 3). For example, if the motor is drawing 30 amps at 250 volts, you have 30 x 250 x sqrt 3 (about 1.73) = 12,975 watts).
How much power does a 3/4 hp motor use?
|Approximate Starting Wattage||Approximate Running Wattage|
|1 1/2 Horsepower||3200||1600|

How many amps does a 1 HP 3 phase motor draw?
Here are the Full Load Amp (FLA) values for typical 230VAC and 480VAC 3 phase motors.
|Motor horsepower||Full load amps 230VAC||Full load amps 460VAC|
