Abstract

The invention relates to a method and device for producing an electric machine, an electric machine with a commutator, having commutator hooks for fixing electric wire windings with solder arranged between the commutator hooks and the wire winding and two electrodes arranged adjacent to each other which are pressed against the commutator hooks. An electric current is passed through the commutator hooks by means of electrodes such that the solder melts and forms a connection to the wire winding.
