The winding overhang of the rotor of an electrical machine is subject to strong centrifugal forces during operation, especially when the machines run at high speed. The winding overhang support prevents the production of relative movements between the winding overhang and the rotor base. These movements result in strong mechanical stresses on the winding bars. The winding overhang support includes an inner ring and an outer ring between which the winding bars are arranged in the region of the winding overhang, the outer ring being shrunk on the inner ring and both the outer ring and the inner ring being interspaced from the lamination stack.
