1. An axial flux machine comprising: a stator located between a first rotor disk and a second rotor disk
wherein:
a central support flange defining a first lateral face and a second lateral face and dividing the stator into a first stator half and a second stator half and having formed flow openings from the second stator half to the first stator half, the central support flange having a plurality of annular segment-like window cutouts which are separated from one another by webs and are distributed uniformly around a central opening for a hub of the stator and in which a plurality of iron cores are held centrally by a groove via the webs;
a first, left stator cover which is mounted on the first lateral face of the central support flange and has a collection channel formed on an outer periphery; and
a second, right stator cover which is mounted on the second lateral face of the central support flange and has a distribution channel formed on an outer circumference, wherein a cooling agent flow from the distribution channel through the flow openings to the collection channel is defined.
