Abstract
A combination starter-generator device includes a power transmission assembly with first and second planetary gear set stages. One or more of the planetary gear set stages includes an idler gear and a ring gear. A clutch arrangement is coupled to effect a delivery mode in which power flows in a first power flow direction and a generation mode in which power flows in a second power flow direction. In delivery mode, input power is received in the first rotational direction from the electric machine and output power is provided in the first rotational direction to the engine as the first power flow direction. In generation mode, one or more of the planetary gear set stages receives input power in the first rotational direction and outputs power in the first rotational direction to the electric machine as the second power flow direction.
