PROBLEM TO BE SOLVED: To provide cooling ducts in an electric machine for enhanced stator cooling duct performance.SOLUTION: An assembly 100 includes a plurality of packages 102 of stacked laminations 104, each package including an outermost lamination having a plurality of radially extending spacer blocks 106. The plurality of radially extending spacer blocks and adjacent axially spaced laminations define a radial cooling duct 122, and the outermost lamination includes a plurality of recesses such that a flow through the cooling duct flows over the plurality of recesses. In one embodiment, at least one adjacent axially spaced lamination defining the radial cooling duct also includes a plurality of recesses. |
