Abstract

A rotor for a commutator machine, having a rotor shaft, a rotor body containing a rotor winding, and a commutator, which has an insulation material body non-rotatably supported on the rotor shaft and has a number of commutator lamellas that are disposed on the insulation material body. Connection lugs that are bent away from the commutator lamellas for connecting connection wires of the rotor winding, in order to use the advantageous ultrasonic torsion welding process to mechanically and electrically connect connection lugs and connection wires without changing the rotor geometry, the insulation material body, is axially supported against the end face of the rotor body oriented toward the end face.
