Abstract
An axial-flow machine has a dimensionally stable assembly, a machine shaft, a rotor fastened on the machine shaft and provided with a rotor hub, permanent magnets disposed circularly around the machine shaft, an adhesive and a brace, which is disposed on the outer circumference of the rotor and encircles it in closed manner and which urges the permanent magnets with a radially inwardly directed tension force, and stators disposed on both sides of the rotor. The permanent magnets are seated on the rotor hub via first adhesive joints equipped with adhesive and adjoin one another via second adhesive joints equipped with adhesive, wherein the permanent magnets, the rotor hub, the brace and the adhesive form the dimensionally stable assembly, the radial and axial dimensional stability of which is determined substantially by the radial tension force of the brace on the permanent magnets.
