A rotor (10) of an electric machine, especially of a hydrogenerator, comprises a rotor yoke (12) with axial winding slots (13) which are arranged in a distributed manner on the outer periphery and into which winding bars (14, 15) of the rotor winding are inserted, the winding ends (16, 17) of which, which emerge axially from the rotor yoke (12), form an end winding (11) which is retained against the acting centrifugal forces by means of a retaining device (19,.multidot., 28) which comprises a number of radial bolts (24). With such a rotor, a secure fixing of the radial bolts is achieved by the radial bolts (24) having heads (25) which are connected to the shank (31) in a fixed manner. |
