Abstract
In a hybrid transmission, a traction motor is mounted between a dry clutch module and a manual gearbox. A slave cylinder is mounted within the rotor of the traction motor to reduce axial length. The rotor is fixedly coupled to an engine crankshaft. The stator may be cooled by circulating engine coolant through the housing. The stator and the rotor may be cooled by spraying transmission fluid into a sealed motor cavity.
