1. A propulsion system, comprising:
an axial-flux rotating electric machine including a first rotor coaxially arranged with a first electric stator;
a second electric stator coaxially arranged with the first rotor and the first electric stator;
a torque converter, including a fluidic stator, a pump, a turbine and a torque converter clutch;
a selectable one-way clutch coupled to the fluidic stator;
wherein the axial-flux rotating electric machine is arranged coaxially with the torque converter;
wherein the first rotor of the axial-flux rotating electric machine is coupled to the pump of the torque converter;
wherein the turbine of the torque converter is rotatably coupled to an output member;
wherein the first rotor is interposed between the first and second electric stators;
wherein the first rotor includes a first plurality of radially oriented permanent magnets affixed to a first side of a disc-shaped backplate;
wherein the first rotor includes a second plurality of radially oriented permanent magnets affixed to a second side of the disc-shaped backplate;
wherein the first electric stator comprises a disc-shape device having a first plurality of electrically conductive windings;
wherein the first plurality of radially oriented permanent magnets are arranged adjacent to a first side of the first plurality of electrically conductive windings in an axial orientation and are separated by a first air gap; and
wherein the second plurality of radially oriented permanent magnets are arranged adjacent to a second side of the first plurality of electrically conductive windings in the axial orientation and are separated by a second air gap.
