Abstract
A rotor for a current-excited electric machine includes a rotor inductor having one or more electrically conductive rotor windings, and at least one slip ring for providing a slip-ring current to the rotor. The rotor also includes a rotor DC-to-DC converter which is designed to convert the slip-ring current flowing via the slip ring into an excitation current through the rotor inductor, the excitation current being increased by a conversion factor.
