The three phase windings of the synchronous machines are always connected in star with neutral earthed. Star connection of windings eliminates the 3 rd harmonics from the line emf. Double layer winding: Stator windings of alternators are generally double layer lap windings either integral slot or fractional slot windings. FIELD: electrical engineering; three-phase windings for ac synchronous and induction motors. SUBSTANCE: proposed asymmetric fractional-pitch winding placed in z - 15 slots on 2p = 6s poles is double-layer m'= three-belt winding with slots per pole per phase q = z/3p = 5/3 assembled of 3 pc coil groups alternating as 2 1 2 1 2 2 2 2 1 repeated c times; novelty is that slot pitch of concentric. It is also to be noted that for fractional slot winding double layer winding is a must and hence conductors per slot must be an even. Assuming number of slots per pole per phase as 2.5 Total number of slots = 2.25 x 3 x 96 = 648. Total number of conductors = 2 x 3 x T ph = 6 x 82 = 492 Hence number of conductors per slot = 492/648 = fraction.
