Abstract
A rotating electric machine, e.g. hydrogenerator, includes a rotor, including a rotor laminate stack extending in a machine axis direction and having a rotor winding which forms a winding head at each of the ends of the rotor laminate stack. The winding head is fastened to a winding head rim, which is arranged concentrically within the winding head and adjoins the rotor laminate stack in the axial direction, to intercept centrifugal forces by bolts passing radially through the winding head, and a fastening designed to safely absorb axial expansions of the winding head. Simple and secure fastening is achieved by the bolts being fastened to the winding head rim in each case on a T-shaped hammer profile, which extends axially and is mounted, axially movable, in a T-shaped groove in the winding head rim, additional couplers are provided that transmit axial expansions of the winding head onto the hammer profile.
