Abstract

A rotor cap for an electric generator, e.g., a high-speed turbogenerator, is disclosed, along with a production method for such rotor cap. The rotor cap is at least partially made of fiber-reinforced plastic material. The rotor cap may have cooling fluid passages, e.g., extending in an axial direction, in the area of the fiber-reinforced plastic material.
