Abstract
A turbogenerator () has a rotor () having a cylindrical rotor body (), which at each of the two ends merges into a shaft end (), and in a middle section has the electromagnetically active region () of the rotor (), in which the rotor () is assembled from a plurality of rotor parts which are interconnected and arranged in series on the rotor axis (). With such a rotor, lower losses and temperatures in the end region of the rotor, and overall a higher limit rating or a broadened output range, become possible as a result of the fact that the rotor body () in the active region () is formed of an easily magnetizable material, especially a first steel, and in that the end sections of the rotor body () which are located outside the active region () and the shaft ends () are formed of a material with reduced magnetizability or of a non-magnetic material, especially a second steel.
