Abstract
A rotor for an electrically excited drive machine includes: a coil per rotor pole with, in each case, one first energizable coil unit, and a rotor core for holding the coils of the rotor poles. The coils have, in each case, at least one second energizable coil unit per rotor pole. The rotor has an interconnecting unit which is designed to interconnect the at least two coil units per coil in a manner which is dependent on an operating point of the electric drive machine in order to set the number of windings of the coil, and in order to electrically connect the coils of the rotor poles for configuring a rotor winding with an overall number of windings which is dependent on the numbers of windings of the coils.
