Abstract
A rotor segment of an electric machine may include a rotor shaft and a laminated core, which is arranged on the rotor shaft in such a way that a gap dimensioned sufficiently large in the radial direction for the passage of a cooling medium is produced between an outer surface of a hollow cylinder shell and an inner surface of the laminated core. The rotor segment may further include two pressure elements that are held on the rotor shaft in a stationary manner such that the pressure elements axially clamp the laminated core. Further, at least one of the pressure elements is designed as a holding segment allowing cooling medium to pass through.
