Pole Pitch, Coil Span, Back Pitch, Front Pitch in Armature Winding | DC Machine | Lap & Wave Winding

Pole Pitch, Coil Span, Back Pitch, Front Pitch, Commutator Pitch in Armature Winding of DC Machines are explained in this video. Lap and Wave winding are explained. Full Pitch and Short Pitch Winding are explained. Progressive and Retrogressive winding, Open and Closed winding, Simplex and Multiplex winding (Duplex, Triplex etc.), Single layer and two layer winding etc. terminologies of winding are also explained. At 7:39 there is a mistake. I am writing pole pitch =Z/pole =Z/slot . That is a mistake. Z/slots is wrong. It would be slots/p. I have mistakenly interchanged slots with poles in the last equation. Correction is explained as below: Z = no. of conductors = no. of slots in single layer winding, because each slot carries only 1 conductor. No. of poles = P No. of pole pairs = P/2 = p Pole pitch = Z/p = Slots/p Music: Acoustic Breeze Royalty Free Music from Bensound www.bensound.com
