Abstract:
An electric machine has a stator that comprises a plurality of laminations with an outer periphery, and each of the laminations has teeth about a central opening such that when the laminations are stacked side-by side to form the stator core, the plurality of teeth of adjacent laminations cooperate to form slots disposed circumferentially about the central opening that are configured to receive a plurality of stator windings. Each of the laminations has a plurality of cooling apertures angularly spaced about the central opening. The cooling apertures of adjacent laminations 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 path transverse to the manifolds and angularly between laminations and adjacent manifolds.
