A synchronous machine having a rotor with a plurality of salient poles which are supported by a rotor rim. The rotor rim is arranged by means of a hollow annular device in mechanical connection with a rotor hub, cooling gas flowing into the annular device relatively close to the hub and leaving at the rotor rim, flowing through cooling ducts in the rotor and stator, through a cooler and out into a cooling gas space which includes a plurality of guide vanes arranged so that the cooling gas on its way from the cooler to the hollow, annular device passes through the guide vanes and is thus put in rotation around the axis of rotation of the rotor. |
