The invention relates to a rotating electric machine (10), in particular a hydrogenerator, comprising a rotor, which comprises a rotor laminate stack (12) extending in the direction of a machine axis (20) and having a rotor winding (15a, b), the rotor winding (15a, b) forming a winding head (15) at each of the ends of the rotor laminate stack (12), said winding head being fastened to a winding head rim (13), which is arranged concentrically within the winding head (15) and adjoins the rotor laminate stack (12) in the axial direction, in order to intercept centrifugal forces by means of bolts (18) passing radially through the winding head (15), and the fastening (16, 17, 18, 21) being designed to safely absorb axial expansions of the winding head (15). In such a machine, simple and secure fastening is achieved by virtue of the fact that the bolts (18) are fastened to the winding head rim (13) in each case on a T- shaped hammer profile (17), which extends in the axial direction and is mounted in axially movable fashion in an associated axial T-shaped slot in the winding head rim (13). |
