Abstract: According to one embodiment, an electric rotary machine includes a stator (12) including a stator core (24) and a stator coil, a first bracket (16) covering one end surface of the stator core, a second bracket (18) covering the other end surface of the stator core, and a rotor (28). A first flow path formation part (40) provided on an outer periphery of the stator core includes a first flow path (F1) extending from one end of the stator core to the other end thereof in the axial direction and a second flow path (F2) extending from one end of the stator core to the other end thereof in the axial direction. A first bracket includes an annular peripheral wall (16a) with an opening end opposed to the one end surface, a bottom wall (16b) opposed to the one end surface with a gap therebetween, and a second flow path formation part (48) formed as a part of the peripheral wall. The second flow path formation part defines an external air flow path (RA) and an internal air flow path (RI).

Abstract: 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.
