1. An electric machine arrangement, comprising:
an electric machine for driving an electrically drivable motor vehicle, having a stator and a rotor,
a component supporting the stator, and
an output element in contact with the rotor for conjoint rotation therewith,
wherein:
the stator is arranged supported relative to the rotor via at least a first bearing in such a way as to be decoupled from a rotary motion of the rotor, wherein the stator is supported with an interposition of a length compensation element in a direction of rotation and is connected to the component supporting the stator at least in an axially movable manner, wherein the length compensation element comprises a coupling rod, wherein the coupling rod is configured for supplying coolant to the stator and is hollow on an inside or is electrically conductive at least in regions for an electrical supply of the stator.
