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

Answer Posted / hemraj

generally,the rating of any machine is decide by losses of
that machine depends on what factor.losses in gen. are
depend only on generated voltage & gen. current. so rating
of gen. is in kva.
in dc motor losses are depend on voltage & current and this
losses are also depend on application of dc motor i.e power
factor of load which is connected to that dc motor. so
rating of dc motor is in kw.
