1. An electric machine arrangement, comprising:
an electric machine having a stator and having a rotor, and a transmission arrangement driven via the rotor, wherein the transmission arrangement is arranged at least in regions in a receiving space formed within the rotor, wherein the transmission arrangement has a first sub-transmission configured as a reducing stage for reducing a rotational speed of the rotor and a second sub-transmission configured as a differential transmission, wherein the first sub-transmission is configured as a planetary transmission, wherein the second sub-transmission configured as the differential transmission is a planetary transmission and the first sub-transmission and the second sub-transmission have a common ring gear;
wherein the second sub-transmission as the differential transmission has, in addition to the common ring gear, a first set of planetary gears, a second set of planetary gears, and a sun gear that is connected in a rotationally fixed manner to a first output shaft.
