Can a dc motor works as a dc generator. If yes , then how?

Answer Posted / sonuram

dc motor and dc generator work based on the mauchul
induction .motor change the electric energy in to mechanical
energy but generator change the mechanical energy in to
electric energy.both construction same.if we supply the
output of generator used as input of motor then we change dc
generator as dc motor.
