Abstract
A hybrid system includes an electric motor/generator or eMachine with a stator received in a cooling sleeve. The stator is pressed into the cooling sleeve to form a press-fit connection. The press fit connection has sufficient strength to carry the complete torque generated by the eMachine, so the stator will never move relative to the sleeve through the life of the hybrid system.
