A rotor for a synchronous machine of a motor vehicle includes an excitation coil configured to generate a magnetic field necessary for rotation of the rotor in a stator of the synchronous machine. The rotor also includes a supply circuit, to which energy is fed contactlessly such that the supply circuit supplies the excitation coil with the energy. The rotor also includes a demagnetization circuit configured to demagnetize the excitation coil, which, upon collapse of the energy supply of the excitation coil, diverts a current flowing through the excitation coil into a circuit branch in which at least one component for demagnetization is arranged, wherein the at least one component is also configured to perform a protection function to protect the supply circuit against an induced voltage generated at the excitation coil.

Rotor for a synchronous machine

An electrical synchronous machine is provided for a rail-free vehicle. The vehicle has drive wheels and the synchronous machine is designed to generate a torque, which propels the vehicle, at the drive wheels. The synchronous machine has a stator and a rotor which rotates around the stator, wherein the stator has a stator winding of at least three-phase construction for forming a rotating stator magnetic field, and wherein the rotor has at least one rotor winding which is designed for forming a rotor magnetic field. A method for at least partially circumferentially establishing a current-excited synchronous machine provides a rotor yoke, provides a large number of rotor poles, fastens the rotor poles to the rotor yoke for forming a rotor, provides a stator, and inserts the stator into the rotor.

Electrical synchronous machine and method for at least partially circumferentially producing an electrical synchronous machine

A rotor element or a star disk which is designed to be arranged on an electrically excited rotor of an electric machine, includes a base which is designed to be arranged in an insert between the axial end of a laminate stack of the rotor and at least one end winding of the rotor. At least one fin is fastened on the base and is designed to protrude in the insert through the at least one end winding axially out of the at least one end winding.
