    • An arrangement for limiting the terminal voltage in an alternator has a fixed stator winding acting on rectifiers and an excitation winding which rotates with the alternator rotor. The arrangement also has a controller and a first slip ring contact which load the excitation winding with excitation current as a function of the magnitude of a delivered voltage, and at least one free-wheeling valve which is conductive during a controller-side interruption of the excitation current and is connected in parallel with the excitation winding. The arrangement includes an auxiliary winding on the rotor. The auxiliary winding continues the excitation winding in the same direction of winding, with the auxiliary winding and the excitation winding being connected at a first connection point. A second slip ring contact operatively connects the first connection point to a machine terminal supplying excitation current. A zener diode is connected in series with auxiliary winding, and a third slip ring contact operatively connects the auxiliary winding to a ground terminal of the alternator or of the controller.
