Abstract: Electric machine assemblies are disclosed. The electric machine assembly includes a stator, a rotor movably coupled with the stator, a starter ring gear component fixedly coupled with the rotor on a first side of the stator, and a transmission coupler fixedly coupled with the rotor on a second side of the stator opposite from the first side. Further disclosed are engine systems and methods of assembling the same, where the engine system includes an engine block with a crankshaft, as well as the electric machine assembly operatively coupled with the engine block such that the starter ring gear component is fixedly coupled with the crankshaft and the rotor on a first side of the stator.
