Abstract
In electric machines having gas-cooled rotor windings which consist of part conductors (5,6) which are placed on top of each other and have an E or U section, relative movements between the part conductor pairs occur during shaft rotation which generate copper abrasion. Such relative movements are inexpensively prevented by a 'covered' riveting of the part-conductor pairs.
