Abstract
In one aspect, an improved electric transmission assembly is provided that includes a hydrodynamic bearing. The electric transmission assembly includes a stator arranged inside of an outer housing. A rotor is configured to be rotatably driven by the stator. The rotor can include a rotor shaft having a first gear configured to driveably engage with a differential. A hydrodynamic bearing is arranged between the rotor shaft and the outer housing. The hydrodynamic bearing is formed from a non-conductive material. Specifically, the hydrodynamic bearing can be formed from a polymeric or plastic material. In one aspect, the hydrodynamic bearing is formed from a non-metallic material.
