Power rating for electrical machines indicates the required supply voltage for smooth running of that machine, it also shows the permissible maximum amount of current which can easily flows through the machine and there will be a chance of breakdown in the machine if those parameters goes beyond this limit.

Why is motor rated in kW?
Motor is rated in kW since it specifies the capacity of the motor to drive its load. It is the active power (kW) that is of interest when a motor drives a load. The motor converts the active power that it draws from the mains into mechanical power that the load consumes/demands. … Thus, a motor is rated in terms of kW.
How is motor rating calculated?
Multiply the motor voltage by the full-load current. The result is in watts. Divide watts by 1,000 to give kilowatts. For example, 230 volts x 20 amps = 4,600 watts; 4,600 watts divided by 1000 = 4.6 kilowatts.
What do motor codes mean?
Codes are defined in MG 1-10.37. 2 by a series of letters from A to V. Generally, the farther the code letter from A, the higher the inrush current per hp. A replacement motor with a “higher” code may require different upstream electrical equipment, such as motor starters.
How can you tell if a motor is VFD?
Three major factors should be considered when determining if a motor is compatible with a VFD: the motor winding insulation, motor bearings and pump operating speed range.
How do I know if a motor is 3 phase?
3 phase motors will have 3 power wires (usually labeled L1, L2, L3) while single phase will only have two wires and a ground.
Is kVA equal to kW?
1. Convert the Real Power in Watts to Apparent Power in kVA (Kilovolt amps). Watts divided by 1000 times the power factor is equal to kilovolt-amps.
kVA And kW Relation for AC And DC Circuits.
|DC Circuit||Power Factor=1||kW= kVA|
What is kW rating of motor?
Three Phase Motors
|MOTOR RATING||HP||APPROX. F.L.C. AT LINE VOLTAGE|
What is rated power kW?
kW stands for kilowatt. A kilowatt is simply 1,000 watts, which is a measure of power. So, for example, the 10,000 watt electric shower in the top bullet point above could also be called a 10 kilowatt shower. … So a 1,000 watt drill needs 1,000 watts (1 kW) of power to make it work, and uses 1 kWh of energy in an hour.
How many kW is a 10 hp motor?
Horsepower (metric) to Kilowatt Conversion Table

|5 horsepower (metric)||3.67749375 kW|
|10 horsepower (metric)||7.3549875 kW|
|20 horsepower (metric)||14.709975 kW|
|50 horsepower (metric)||36.7749375 kW|
How many amps is 3 horsepower?
Common Horsepower to Amps Conversions
|3 HP||20.7 A||120 V|
|3.5 HP||24.2 A||120 V|
|4 HP||27.6 A||120 V|
|4.5 HP||31.1 A||120 V|
What is BKW of motor?
Bkw (brake kilowatts) is the power actually required to drive a piece of equipment. In this context, kw would be the power rating of the chosen driver. (Oftentimes the next standard size larger than the bkw.) … It stands for brake kilo watt.
What does SFA stand for on a motor?
Service Factor Amps, or S.F.A., represents the amount of current the motor will draw when running at the full Service Factor. In the example nameplate, the S.F.A. is eight amps at 230 volts. Continually exceeding the S.F.A. shown on the nameplate can shorten motor life.
