Abstract
A rotating electrical machine includes a rotor configured to rotate about an axis. The rotor includes a rotor lamination stack having a plurality of sheets pressed into a composite assembly in an axial direction and being radially divided into an inner mechanical part and an outer electrical part. A rotor winding is disposed in the electrical part of the rotor lamination stack. A stator is concentrically surrounding the rotor. A plurality of shear bolts is disposed in the mechanical part and configured to reach through the rotor lamination stack. A plurality of further bolts is disposed in the electrical part, the plurality of shear bolts and a plurality of further bolts being configured to press the plurality of sheets in the axial direction.
