Zusammenfassung:The invention relates to a method for operating an electric machine that is coupled to an internal combustion engine in a motor vehicle. The electric machine has a stator winding, a rotor winding, a field controller assigned to the rotor winding, and a power converter which is connected downstream of the stator winding and which comprises actuatable switching elements. An excitation current flowing through the rotor winding is specified dependent on an operating mode of the electric machine, and the electric machine is operated as a generator in a first generator operating mode in order to brake the motor vehicle, the braking energy that is recovered during the braking process being stored.
