Abstract
An electric machine includes a stator formed from a plurality of stator laminations arranged in a first lamination group and a second lamination group. The first lamination group and the second lamination group form a tortuous flow path that extends across the stator. The first lamination group includes at least two of the plurality of stator laminations joined together. The at least two of the plurality of stator laminations include a first plurality of cooling channel defining members. The second lamination group includes a second plurality of stator teeth and a second plurality of cooling channel defining members. The second plurality of cooling channel defining members of the second lamination group are circumferentially offset from corresponding ones of the first plurality of cooling channel defining members of the first lamination group.
