Abstract
A method for detecting a fault in a generator unit that has an electrical machine including a rotor winding and a stator winding and a rectifier connected thereto, via which the electrical machine is connected to an electrical system of a motor vehicle. Whether or not the fault exists is determined as a function of an excitation current traversing the rotor winding of the electrical machine and as a function of a setpoint value of the excitation current.
