Abstract
The present disclosure relates to electrical machines and methods for cooling active elements of electrical machines. More in particular, the present disclosure relates to generators and methods for cooling adjacent active rotor elements and/or adjacent active stator elements of a generator of a wind turbine, e.g. of a direct drive wind turbine. An electrical machine comprises a rotor including a plurality of active rotor elements, a stator including a plurality of active stator elements, and an air gap separating the active rotor elements and the active stator elements. The electrical machine further comprises a radiation absorber arranged between a first and a second adjacent active rotor elements or between a first and a second adjacent active stator elements.
