Cooling system for a stator assembly

A stator assembly is provided having a generally annular stator core including a plurality of radially inwardly extending stator teeth. A stator wire is wound around each of the plurality of stator teeth to form a plurality of stator coils. Each of the plurality of stator coils are spaced apart to at least partially define a plurality of generally axially extending cooling channels through which a cooling medium, such as oil, flows. Additionally, the plurality of stator teeth each include a respective flanged end portion each adapted to retain an axially extending strip member. The strip member at least partially defines the cooling channel. The cooling medium operates to cool the plurality of stator coils. In the preferred embodiment, at least a portion of the flow of the cooling medium within the cooling channel is turbulent. Additionally, an electromechanical hybrid transmission is disclosed with the stator assembly provided.
