Abstract
Official abstract text for this publication.
A rotating electric machine includes a rotor, having a rotor laminate stack extending in the direction of a machine axis and having a rotor winding, the rotor winding forming a winding head at each of the ends 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 the axial direction, in order to intercept centrifugal forces by means of 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 virtue of the bolts being fastened to the winding head rim in each case on a T-shaped hammer profile, 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.
