Abstract: PROBLEM TO BE SOLVED: To provide a rotor for a high-speed electrical machine. SOLUTION: This rotor for a high speed electrical machine is provided with a stack of several thick solid disks 1, which are adjacently aligned on a shaft. The solid disk 1 has a specified fastening face 5 on the end surface. A tie rod 2 penetrates the stack in the axial direction in a region of the fastening face 5. The tie rod 2 fastens the solid disks 5 mutually on the fastening faces 5. In order to save weight and material, a recessed part 8 having rotational symmetry for the central part adjacent to the peripheral region of each of the solid disks 1 is formed on at least one end surface of the solid disk 1.

Abstract: A rotor for a high-speed electrical machine is specified, which rotor is composed of a stack of several thick solid disks (1) axially lined up next to one another, the solid disks (1) having a defined pressing surface (5) at their end faces, and tie rods (2) passing through the stack in the axial direction in the region of the pressing surfaces (5). In this case, the tie rods (2) press the solid disks (1) against one another at the pressing surfaces (5). Furthermore, in order to save weight and material, a central, rotationally symmetrical recess (8) adjoining the marginal region of each solid disk (1) is provided on at least one end face of the solid disk (1).
