1.	When coil sides are pole pitch apart, the DC armature winding is called as ___________(a) Multiplex(b) Fractional-pitch(c) Full-pitch(d) Pole-pitchThis question was addressed to me in an internship interview.The origin of the question is Armature Winding and Commutator in division Armature Windings of DC Machines
Answer» Correct choice is (c) Full-PITCH To explain: Pole pitch is called as center to center distance between two adjacent poles. When measured in electrical degrees ONE pole ITCH is equal to 1800. Coil span is simply a peripheral distance between two sides of a coil. If the coil span is equal to the pole pitch, then the armature winding is said to be full pitched coil.
