Abstract
A rotor body for a rotor of a rotating electric machine, in particular a turbogenerator, has at least one pole axis extending perpendicularly to a longitudinal center axis of the rotor body. At least one section of the rotor body has at least two layers produced from different materials, which layers are arranged in alternation, wherein the materials differ from each other with respect to the electrical conductivity thereof. A layer sequence direction of a layer structure formed by the layers extends perpendicularly to the pole axis and to the longitudinal center axis.
