Abstract (en)

[origin: WO2007128379A1] A rotor exhibits a carbon commutator (4). For the manufacture of the rotor, an insulating support (9) is positioned on the rotor shaft (1). The insulating support (9) features lugs (13), around which the winding ends (8) of the rotor coils (3) are wound; after removal of the insulation, the winding ends (8) are provided with an electrically conductive adhesive. The commutator (4) is then put on the lugs (13) with the winding ends (8). By means of this process, the winding ends (8) are mechanically and electrically directly connected to the corresponding commutator segments.
