Abstract
A stator includes an elongate core defining an inner volume to receive a rotor of an electric machine. The core includes a yoke and an array of teeth extending from the yoke toward the inner volume. The array of teeth defines slots between each pair of adjacent teeth in the array. Each slot includes a first slot region adapted to hold at least a portion of a conductive winding and a second slot region adapted to hold at least a portion of a conductive winding. The first slot region is defined by two non-parallel opposing slot side portions, and the second slot region is defined by two parallel opposing slot side portions.
