Electric axial flux machine with pretensioned stator components, and electric machine assembly comprising such an electric axial flux machine

An electric axial flux machine comprising a stator with at least one stator half, a rotor arranged in an axial direction relative to the stator and rotatably mounted relative to the stator, and a rotor shaft contacting the rotor in a non-rotatable manner, wherein a magnetic force acts between the rotor and the stator in the axial direction, wherein a preload pushes the at least one stator half away from the rotor in order to counteract the magnetic force, and wherein the at least one stator half itself generates the preload due to its rigidity, wherein the at least one stator half has a first stator half and a second stator half which are connected to one another radially on an outside, wherein the stator has a stator housing which has a first half shell, which defines an outer side of the first stator half, and a second half shell, which defines an outer side of the second stator half, and the first half shell or the second half shell has an inherent rigidity that causes the preload which counteracts the magnetic force, and wherein the preload is applied such that at least one of the first or the second half shell has such a shape in a free state, before the stator halves are exposed to a strong magnetic field and are connected to the rotor shaft via a bearing arrangement, that extends continuously and increasingly away from the rotor, starting from a radially outer region towards a radially inner region.
