Claim 12:
13. A method of forming a stator assembly, the method comprising:
forming a first single-layer winding of a first electrically conductive member including a plurality of turns around a first stator tooth projecting radially inward towards a rotor from a base portion,
wherein the first electrically conductive member has a thickness in the radial direction that is less than its width in a direction perpendicular to the radial direction;
forming a second single-layer winding of a second electrically conductive member including a plurality of turns around a second stator tooth projecting radially inward towards the rotor from the base portion,
wherein the second electrically conductive member has a thickness in the radial direction that is less than its width in a direction perpendicular to the radial direction,
wherein the first stator tooth and the second stator tooth are adjacent to each other,
wherein forming the first single-layer winding comprises forming a single-layer winding such that a width of each of the plurality of turns of the first electrically conductive member increases in a first circumferential direction from a distal portion of the first stator tooth to a proximal portion of the first stator tooth adjacent the base portion and forming a single-layer winding such that a width of each of the plurality of turns of the second electrically conductive member increases in a second circumferential direction from a distal portion of the second stator tooth to a proximal portion of the second stator tooth adjacent the base portion such that a slot between the first stator tooth and the second stator tooth is substantially filled,
wherein forming each of the first and second single-layer windings comprises forming a single-layer winding such that a turn thickness in the radial direction of each of the plurality of turns of the first and second electrically conductive members increases from the proximal portions of the first stator tooth and the second stator tooth adjacent the base portion to the distal portions of the first stator tooth and the second stator tooth;
placing a thermally conductive member in thermal contact with an entire radial length of the first electrically conductive member at a longitudinal end face of the first single-layer winding; and
placing an end bell in thermal contact with a longitudinal end face of the thermally conductive member.
