摘要： The present disclosure relates to electrical machines, cooling systems and methods for cooling active elements of electrical machines. More in particular, the present disclosure relates to cooling systems and methods for cooling active rotor and/or stator elements of a generator of a wind turbine, e.g. of a direct drive wind turbine. A cooling method comprises supplying a cooling fluid to an air gap through one or more primary inlets of an electrical machine for cooling a plurality of active elements of a rotor of the electrical machine and/or a plurality of active elements of a stator of the electrical machine separated by the air gap. The method further comprises reversing a direction of flow of the cooling fluid such that the cooling fluid is extracted from the electrical machine through one or more primary inlets.

摘要： Generator (4), in particular of a wind turbine (1), for producing electrical power comprising
- a stator (5) comprising stacked lamination sheets (21, 21a, 21b, 21c) and stator windings (18), wherein the lamination sheets (21, 21a, 21b, 21c) each comprise a stator tooth area (29) radially extending from a stator yoke area (33), and
- a rotor (6) comprising magnets (11), in particular permanent magnets (11), and being rotatable around a rotational axis (14) extending in an axial direction (13), wherein the magnets (11) and the stator windings (18) face each other via an air gap (10) between the stator (5) and the rotor (6), the air gap (10) extending in a circumferential (22) and axial direction (13),
wherein the at least one axial stack (40) of lamination sheets (21, 21a, 21b, 21c) further comprises at least one cooling channel (43) for a cooling fluid having at least one inlet opening (44) on an air gap side (45) and at least one outlet opening (46) at a radially opposite non-air gap side (47) of the stack of lamination sheets (21, 21a, 21b, 21c), characterized in that the inlet openings (44) and the outlet openings (46) are arranged in a staggered manner in axial direction (13), wherein each inlet opening (44) is associated with two axially shifted outlet openings (46) such that cooling fluid entering the cooling channel (43) through the inlet opening (44) flows axially in opposite courses and radially to the respective associated outlet openings (46).
