Abstract (en)
[origin: WO2021083764A1] The invention relates to an axial flux machine (10), in particular a single-sided axial flux motor, for an electrical machining device (34), having a machine shaft (12), in particular a motor shaft, a disc-shaped stator (20) and a disc-shaped rotor (14) which is arranged adjacent to the stator (20) in the axial direction (A) of the machine shaft (12), wherein the stator (20) is formed as a winding carrier (22) with a plurality of stator teeth (44) for at least one stator winding (24) and the rotor (14), which is connected to the machine shaft (12) in a rotationally fixed manner, can be set in a rotational movement relative to the stator (20). According to the invention, the rotor (14) of the axial flux machine (10) has a rotor yoke (62) which is designed as a bidirectional fan (64) or which is permanently connected, in particular bonded, to a bidirectional fan (40) by a joining process, the bidirectional fan (40) having at least one radial (66) and one axial air flow direction (68) for cooling the axial flux machine (10), in particular for cooling the stator (20) and the rotor (14). The invention also relates to an electrical processing device (34) with an axial flux machine (10).
