Abstract
A rotor for a high-speed electrical machine is specified, which rotor is composed of a stack of several thick solid disks axially lined up next to one another, the solid disks having a defined pressing surface at their end faces, and tie rods passing through the stack in the axial direction in the region of the pressing surfaces. In this case, the tie rods press the solid disks against one another at the pressing surfaces. Furthermore, in order to save weight and material, a central, rotationally symmetrical recess adjoining the marginal region of each solid disk is provided on at least one end face of the solid disk.
