Abstract:
A stator core assembly for an alternator having a rotor assembly which presents a rotating, alternating polarity magnetic field, the stator core assembly having an annular core defining an outside diameter, an inside diameter, and a plurality of radially projecting winding slots opening to the inside diameter but terminating short of the outside diameter, the core further defining a lead side and an opposite non-lead side, the stator core assembly further comprising:(a) at least two electrical conductors designated as conductor A and conductor B, (b) the conductors positioned into the winding slots where: n=number of phases of the stator core assembly, m=number of the winding slots in the stator core, with the winding slots numbered 1 through m, L=number of layers of the conductors A and B in the winding slots, wherein a pair of the conductors A and B define one layer, said one layer comprising: (c) a first lead of conductor A is placed into a slot number 1 with the conductor A first lead extending from the stator lead side end, (d) a first lead of the conductor B is placed into slot number n+1 with the conductor B first lead extending from the stator lead side end, (e) the conductor A is placed into the slot number n+1 thereby forming an end loop on the non-lead side end and lying in the slot number n+1 radially shifted inwardly from the conductor B, wherein the pair of the conductors A and B lying in the same slot define a layer L, (f) the conductor A is placed into a slot number 2n+1 thereby forming an end loop on the lead side, (g) the conductor B is shifted into the slot number 2n+1 thereby forming an end loop on the non-lead side and lying in the slot number 2n+1 radially shifted inwardly from the conductor A; wherein the conductors A and B positioned as recited herein the preceding section (a) though (g) for all the slots numbered through m+1âˆ’n, thereby forming a first layer L, and (i) the conductor A extending from the slot number m+1âˆ’n on the lead side end thereby defining a conductor A second lead, and the conductor B extending from the slot number 1 thereby defining a conductor B second lead.
