One horsepower = 746 watts or .746kW. Run the motor for an hour and this will equal .746 kWh.
you need the current of motor or the KW/HP rating
To answer this question the motor voltage and amperage is needed.
Look at the motor nameplate and it shoud have the amp draw on it. If the nameplate is missing, then the amp draw depends on what type of motor it is. The basic calculation to get you in the ball park would be as follows: 1 HP = 0.75 KW 7.5 HP = 5.63 KW Assume the efficiency of the motor is 80%, then the power supplied will need to be 5.63/0.8 = 7.04 KW amp draw = 7040/220 = 32 amps <<>> For calculation purposes the electrical code book states that a 7.5 HP motor draws 40 amps.
The first thing that has to be done is find the amperage of the motor. Amps = HP x 746/1.73 x E x %eff x pf. Amps = 10 x 746 = 7460/1.73 x 208 x .85 x .86 = 7460/179 = 42 amps. A standard motor's efficiency between 5 to 100 HP is .84 to .91. A standard motor's power factor between 10 to 100 HP is .86 to .92. The formula for kilowatts is kW = I x E x 1.73 x pf/1000 = 42 x 208 x .86 = 7513 kW Use this kW number times the amount of hours the motor runs to get kW/h. Use that figure for kW/h times the rate you pay for a kW/h in your area to give you the answer that you are looking for.
To convert bhp to kW simply multiply the bhp figure by .7457
To convert horsepower (hp) to kilowatts (kw), you can use the conversion factor of 0.746. Therefore, for a 100 hp motor, the power in kilowatts would be 100 hp * 0.746 = 74.6 kW.
A 7.5 kW motor is equal to 9.916 horsepower.
How to calculate motor kw for cranes
About 1/2 hp
To calculate the electricity consumption for a 208 HP motor for one hour, you would need to know the motor's efficiency and the voltage it operates at. Typically, you can use the formula: Power (kW) = (HP x 0.746) / Motor Efficiency Once you have the power in kW, you can multiply it by the number of hours to determine the electricity consumption in kilowatt-hours (kWh).
200 hp requires about 149kW
To calculate the kilowatts per hour used by a 1.5 hp electric motor, you first convert horsepower to kilowatts: 1.5 hp is approximately 1.12 kW (1 hp ≈ 0.746 kW). If the motor runs continuously for one hour, it would consume about 1.12 kWh. However, the actual consumption may vary based on the motor's efficiency and load conditions.
what formula is used for calculate flow rate of pump vs kw
600 KW
you need the current of motor or the KW/HP rating
To answer this question the motor voltage and amperage is needed.
The conversion factor is 0.746. So, hp x 0.746 = kW
