We know that
KW=KVA*PF
Therefore according to this eq if pf is known then the rating will be in KW either rating will be in KVA.
In the generator pf is depend on the load because it convert mechanical to electrical energy.but in motor electrical convert into mechanical energy in which pf is constant.
Therefore generator rating in KVA & motor rating in KW.
