Web30 sep. 2024 · When the poles of the rotor move under the armature conductors on the stator, the magnetic field cuts the armature conductors. Therefore, EMF is induced in these conductors by the electromagnetic induction. This induced EMF is of alternating nature because field poles of alternate polarity successively pass by the armature conductor.
