Gas-cooled rotor for a turbo-generator with air gap pick up. Each rotor slot comprises a conductor bundle with a large number of tangentially extending cooling channels, which are connected to an inlet chamber (17) on one side of the conductor bundle and an outlet chamber (18) on the other side of the conductor bundle. The conductors of the conductor bundle are fixed with respect to each other by means of a plurality of radial rods (8) embedded into the conductor bundle, and a small, radially inner portion and a small, radially outer portion of the conductor bundle are fixed in the tangential direction by means of an inner (12) and an outer (10) spacing device, respectively. The slot wedge member is provided with a plurality of substantially evenly distributed inlet channels (19) and intermediate, substantially evenly distributed outlet channels (21). A plurality of inlet channels and a plurality of outlet channels are formed in a wedge portion which lies between two spacing bodies (10) located adjacent to each other in axial direction and belonging to the radially outer spacing device. |
