Abstract

See full text

An electric machine includes a stator core having a plurality of stacked laminations that are arranged in sets that each define a circumferentially extending slot through a thickness of the set. The sets are circumferentially rotated relative to each other in sequence such that each slot only partially overlaps with one or more adjacent slots to form a continuous helical cooling path around the stator core. Windings are supported on the stator core.
