why generaotr rating is in kva and dc motor in kw?

Answer Posted / sathishkumar

generator is a source and the losses only due to current
(iron loss) and voltage (copper loss) so there is no power
factor involved so capacity is P=V*I in terms of KVA.
where as in motor there is either inductive load(laaging
P.F)or capacitive load(leading P.F)involved so capacity is
P=V*I*power factor i.e interms of KW.
