Abstract
A stator for an electric machine is formed in stratified layer forming a core having axial slots, and a plurality of hurdle-shaped conductors. Each conductor includes first and second uprights disposed in the slots, and a bridge connecting the uprights and extending circumferentially over a core end surface. The first upright is radially closer to a core central axis than the second upright. Each bridge steps radially outward from the first upright to the second upright. Radially adjacent bridges nest next to one another without crossing over one another. A junction between the first end of the bridge and the first upright defines a radially outward-facing ledge, and a junction between the second end and the second upright defines a radially inward-facing ledge. Each bridge passes over the outward-facing ledge of its radially inwardly adjacent conductor and passing over the inward-facing ledge of its radially outward adjacent conductor.
