Abstract:
1. A rotating electric machine comprising: a rotor, which comprises a rotor laminate stack extending in a machine axis direction and having a rotor winding, the rotor winding forming a winding head at each end of the rotor laminate stack, said winding head being fastened to a winding head rim, which is arranged concentrically within the winding head and adjoins the rotor laminate stack in an axial direction, in order to intercept centrifugal forces by bolts radially passing through the winding head, and a fastening of the winding head to the winding head rim being designed to safely absorb axial expansions of the winding head, the bolts are fastened to the winding head rim on a T-shaped hammer profile, which extends in the axial direction and is mounted in an axially movable fashion in an associated axial T-shaped groove in the winding head rim, additional couplers are also provided that transmit the axial expansions of the winding head onto the T-shaped hammer profile, the additional couplers include a radial part and an axial connector being provided between the winding head and the T-shaped hammer profile, and the T-shaped hammer profile engages with said radial part, which is bent back radially outwards, behind the winding head and is connected to the winding head on said radial part by said axial connector.
