Abstract: The invention relates to a rotor for a synchronous machine of a motor vehicle, the rotor having: an excitation coil (LER) for generating a magnetic field needed for rotation of the rotor in a stator of the synchronous machine; a power supply circuit (1R) which can be supplied with energy in a contactless way so that the power supply circuit (1R) supplies the excitation coil (LER) with energy to generate the magnetic field; and a demagnetisation circuit for demagnetising the excitation coil, which, when the energy supply to the excitation coil (LER) breaks down, diverts a current flowing through the excitation coil (LER) into a circuit branch containing at least one demagnetising component (DZR1), the at least one component (DZR1) also having a protective function for protecting the power supply circuit from an induction voltage generated at the excitation coil (LER).
