A method for manufacturing a rotor for an electric machine, for example, a permanent-magnet excited rotor for a high-speed a.c. machine, the rotor including an inner part constituting a rotor body and an outer part including a capsule tube which, when the rotor is completed, surrounds the rotor body with a shrinkage fit, includes fixing a first of the parts in a vertical direction in relation to a counter-support, and releasing the second part from a location above the first part so that it will fall within the fixed first part under the influence of gravity.
