Abstract
An electric machine is provided. The electric machine may comprise an inlet and a stator fluidly coupled to the inlet. The stator may comprise a first cooling channel formed in the stator with a first cross-sectional area. A second cooling channel may be formed in the stator and have a second cross-sectional area. The first cross-sectional area may be less than the second cross-sectional area. The electric machine may also include an outlet fluidly coupled to the stator. A stator assembly is also provided. The stator assembly may include a first channel with a first cross-sectional area and a second channel with a second cross-sectional area. The second cross-sectional area may be less than the first cross-sectional area.
