motors are rated in kw why because for motor the load is mechanical load. only active power converted to mechanical power is significant and in motor rotational losses,frictional and windage losses, we cant express these losses in VA, only expressed in KW. hence the motor rating in KW

the motor having voltage rating above 480 volt is hv motors and motor having rating below 480 volt is lv motors. generally motor above 185 kw is hv or mv motor and motor below 185 kw is lv motor.
you need the current of motor or the KW/HP rating

The mechanical load of a motor determines the necessary output power rating of an electric motor. As mechanical loads are defined in terms of watts (or, in North America, horse power), then motor's output must be rated in watts, too.The so-called 'power' rating of a transformer is determined by the rated voltage and the rated current of its secondary winding. The product of these two quantities is the transformer's rated 'apparent power', expressed in volt amperes.Incidentally, the symbol for "kilowatts" is "kW", not"KW's"!

The equivalent rating for a 750-watt motor is approximately 1 horsepower (hp).

Motors are rated according to their output power, expressed in watts or kilowatts (or horsepower, in North America). This is because the motor's rating must be matched to the power requirements of its mechanical load.
Because the kilowatt is used to measure power. So, if you want to define the output power of a motor, it is usual to use kilowatts.

It depends on the current rating of the armature winding, which will determine its input power. It's output power then depends on the motor's efficiency.
A 7.5 kW motor is equal to 9.916 horsepower.
The kW rating of a transformer can be calculated by multiplying the kVA rating by the power factor. For example, if the power factor is 0.8, then the kW rating of a 100 kVA transformer would be 80 kW. You can also use the formula: kW = kVA x power factor.
Depends upon the Kw rating of the generator. The higher the Kw rating the more fuel will be used.
