Abstract:
An electric machine includes a stator core defining circumferentially-arranged slots each having radial pin positions arranged to define radial layers and a hairpin winding including a first path of interconnected hairpins disposed in the stator core. The hairpins are arranged such that a leg portion of each hairpin is routed through a radial pin position of each slot wherein at least one uniquely-pitched hairpin is provided along the first path to induce a first shift in a trailing portion of the first path.
