Abstract
A current transmission device for a separately excited synchronous machine includes a stator comprising a ferrite core and a rotor having a further ferrite core. At least one coil can be arranged at the ferrite core, at least one further coil can be arranged at the further ferrite core, the rotor is connected to the stator in a rotatably supported manner, and at least one of the ferrite cores comprises a plurality of ferrite segments which are receivable in a receiving matrix so that current can be transmitted contactlessly between the coil and the further coil by induction.
