Abstract
An electrified drivetrain system that maximizes power density, is readily packaged, and improves drivability is described. It includes a propulsion system having an axial-flux rotating electric machine, a torque converter having a selectable one-way clutch, and an output member that is couplable to a drivetrain. The axial-flux rotating electric machine include a first rotor coaxially arranged with a first electric stator. The torque converter includes a fluidic stator, a pump, a turbine and a torque converter clutch. The axial-flux rotating electric machine is arranged coaxially with the torque converter. The first rotor of the axial-flux rotating electric machine is coupled to the pump of the torque converter, and the turbine of the torque converter is rotatably coupled to the output member.
