Abstract
A gas-cooled generator has a rotor rotatable about an axis, a stator surrounding the rotor concentrically and a rotating exciter connected to the rotor. The stator, rotor and exciter are arranged along the axis on a common base frame. A first cooler configured to cool the rotor and stator and second cooler configured to cool the exciter are connected to one another for the exchange of cooling gas via the base frame. At least one tube running in the base frame provides the connection between the first and second coolers.
