Patent ID: 8860278

Claim:
A 3-phase electric machine comprising: a stator assembly comprising: a stator having 72 slots; and first and second windings that are arranged in each of said 72 slots, the first and second windings each having a width in a radial direction and a thickness in a direction perpendicular to said radial direction, wherein a ratio of said width to said thickness is between 3.0:1 and 4.5:1; wherein the 72 slots include 8 different groups of 9 adjacent slots, each of the 8 different groups of 9 adjacent slots including: a first set of the first and second windings that are connected to a first one of three phases and that are arranged in first, second, and third adjacent ones of the 9 adjacent slots; a second set of the first and second windings that are connected to a second one of the three phases and that are arranged in fourth, fifth, and sixth adjacent ones of the 9 adjacent slots; and a third set of the first and second windings that are connected to a third one of the three phases and that are arranged in seventh, eighth, and ninth adjacent ones of the 9 adjacent slots; and a rotor assembly including a plurality of slots.
