摘要： 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.

摘要： A rotating electric machine includes a rotor configured to rotate about an axis. The rotor includes a rotor laminate stack having layered laminations pressed in an axial direction to form a composite, the rotor laminate stack being radially divided into an inner mechanical region and an outer electrical region. A rotor winding is disposed in the electrical region of the rotor laminate stack. A stator concentrically surrounds the rotor. A press plate is configured to press the layered laminations in the axial direction, the press plate being radially divided into a separate inner press plate and a separate outer press plate so as to correspond to the radial division of the rotor laminate stack.
