Abstract
An electric machine includes a stator core and a hairpin winding. The stator core defines slots that are circumferentially arranged between an inner diameter and an outer diameter of the stator core. Each slot has a plurality of pin positions that is arranged in a direction that extends from the inner diameter toward the outer diameter. The hairpin winding has a plurality of paths of interconnected hairpins that correspond to a first electrical phase of the electric machine. The hairpins are arranged to occupy a portion of the pin positions according to a pattern that repeats at angular intervals along a circumference of the stator core. The pattern includes hairpins occupying each pin position within a first of the slots, harpins occupying exactly half the pin positions within a second of the slots, and harpins occupying exactly half the pin positions within a third of the slots.
