DC machines are broadly of two types viz Motor or generator.
Both works on the principle of electomagnetic induction.
Generator:- Due to relative motion between magnetic flux
and winding, an emf is induced in it.
Motor: Due to the current flowing through the winding and
magnetic field flux, a force is experienced by the
conductor.
