Abstract

The invention relates to a rotor, in particular for a current-excited synchronous machine, comprising a rotor main body which has a plurality of rotor teeth, the rotor teeth being wound with a conductor material in order to form a winding, the conductor material having conductor ends which, in order to produce an electrical connection, are pressed axially against a stop via a contact element, and the contact element or the stop being designed to electrically connect, in the circumferential direction, at least two conductor ends.
