Abstract
Embodiments of the invention provide an electric machine module including an electric machine with a stator assembly. The stator assembly includes a plurality of stator laminations and the plurality of stator laminations include a plurality of different outer diameters. The plurality of stator laminations are positioned relative to one another to form radially-extending fins. At least one circumferential coolant channel is defined along the circumference of the stator assembly by the plurality of stator laminations at least partially between the radially-extending fins.
