Abstract:
1. A method of producing an electric motor with a commutator, wherein the commutator comprises at least one commutator hook for mounting at least one electric wire winding, the method comprising: arranging a solder between the at least one commutator hook and the at least one wire winding; pressing a pair of electrodes that are arranged adjacent to each other and angled to each other against the at least one commutator hook; passing an electric current through the at least one commutator hook via the pair of the electrodes to melt the solder and form a connection to the wire winding; pressing a free shank of the at least one commutator hook about a bending area formed at a mating surface against the mating surface with the pair of the electrodes, wherein the at least one wire winding is positioned between the free shank and the mating surface; and; mechanically pressing the free shank with the pair of the electrodes in a direction of the mating surface prior to passing the electric current through the at least one commutator hook.
