Abstract
A disc rotor machine for a motor vehicle drive is disclosed that includes a disc-shaped stator. The stator has a plurality of core segments-, which are distributed in a circumferential direction and are rigidly connected to one another by means of at least one retaining ring, and a plurality of coil windings each extending around a core segment. The disc rotor machine also comprises a rotor which is mounted rotatably relative to the stator, the rotor having a first rotor disc arranged adjacent to the stator towards a first axial side and a second rotor disc arranged adjacent to the stator towards a second axial side opposite the first axial side, which rotor discs can be driven by a plurality of coils of the stator which are distributed in a circumferential direction and include the core segments and coil windings. The disc rotor machine further comprises a cooling device which cools the coils during operation, the stator having a carrier wheel which accommodates the coil windings and is connected to the at least one retaining ring, the carrier wheel forming a cooling channel portion of the cooling device that directly accommodates at least one of the coil windings.
