Methods and systems for an electric motor system are provided. In one example, a motor system is provided which comprises a first electric machine rotationally coupled to a second electric machine by a planetary gear set that has three components: a ring gear, a sun gear, and a carrier with a plurality of planet gears. In the system, the first electric machine varies in size from the second electric machine and one of the planetary assembly components is permanently grounded.
