Abstract

See full text

The present invention provides a stator assembly for an electromechanical hybrid transmission. The stator assembly is generally annular and defines a centrally located rotor aperture configured to accommodate a rotor. The stator assembly includes a stator core having a plurality of radially inwardly extending stator teeth, and a stator wire wound around each of the stator teeth to form a plurality of stator coils. Epoxy resin is applied between each pair of adjacent stator teeth. The epoxy resin defines a plurality of stator cooling channels located in close proximity to the stator coils, and a plurality of rotor cooling channels located in close proximity to the rotor aperture. A cooling medium is disposed within the stator cooling channels and the rotor cooling channels such that the stator coils and a later assembled rotor can be cooled.
