Summary:A rotor (5) for a high-speed electrical machine comprises a rotor shaft (51), the shaft (51) comprising a rotor core (55) and a rotor sleeve (56). A compensation element (57) is arranged between the rotor core (55) and the rotor sleeve (56) to absorb differences in thermal expansion of the rotor core (55) and the rotor sleeve (56). The rotor (5) is designed to be suited for use in a high speed electrical machine at more than 100'000 revolutions per minute.
