WebMotional EMF of DC Motor. When the armature is stationary, no motional e.m.f. is induced in it. But when the rotor turns, the armature conductors cut the radial magnetic flux and an e.m.f. is induced in them. As far as each individual coil on the armature is concerned, an alternating e.m.f. will be induced in it when the rotor rotates.
