Abstract: In a generator with an indirectly gas-cooled, in particular air-cooled, stator winding (21), the end regions of the stator bore (23) are to be designed in such a way that the conductor bars are shielded as effectively as possible by the laminated stator core (20) against magnetic fields inducing eddy currents, but, on the other hand, a specific radial dimension between the rotor retaining ring (12) and the laminated stator core (20) is ensured. According to the invention, for this purpose, the end region of the stator bore is designed with four axial zones having a different diameter profile. A first zone (I) is the interior of the stator with the constant nominal stator bore diameter (DI). Toward the end face of the stator is arranged a second zone (II) with a stator bore diameter (DII) widening toward the end face.
