Abstract
In a rotating electrical machine, in particular a generator, different components, such as, for example, rotor, stator rod and end zone, are cooled as required by associated external fans, whereby the cooling power requirement is reduced. The method for cooling includes a plurality of cooling fans arranged for cooling different components of the machine, wherein a cooling fan is individually controlled in its cooling performance in accordance with the temperature of the associated component.
