Abstract
An electric machine has a stator that comprises a plurality of laminations with teeth and cooling apertures about a central opening. When the laminations are stacked to form the stator core, the teeth of adjacent laminations cooperate to form slots disposed circumferentially about the central opening that are configured to receive a plurality of stator windings, and the cooling apertures angularly spaced about the central opening cooperate to form cooling manifolds that extend along a length of the stator core. A portion of the laminations has their cooling apertures offset from other laminations in the stack in a manner to create a plurality of flow paths transverse to the manifolds. The transverse flow paths extend angularly between laminations and adjacent manifolds. A header assembly directs flow into and out of the stator core.
