description	A method for switching off a current-excited synchronous machine of a motor vehicle, the current-excited synchronous machine having a rotor supplied by an excitation circuit of power electronics and a stator supplied via a bridge circuit of the power electronics, the method including interrupting a current supply to the rotor and the stator. The method further includes switching over the excitation circuit of the power electronics to a first freewheeling position, whereby energy contained in the excitation circuit and in the rotor is fed into a first energy store via a first feedback arrangement, and switching over the bridge circuit of the power electronics to a second freewheeling position, whereby energy contained in the bridge circuit and in the stator is fed into a second energy store via a second feedback arrangement.
