1. A method for producing an electrically-conducting and mechanically solid connection between insulated armature winding wires and wire-engaging hooks on the lamellas of a commutator comprisingengaging said insulated winding wires with said hooks,before bending the hooks to engage the commutator, at least partially destroying the insulation on the winding wires in the area of engagement with the hooks, thereby producing insulation residue,bending the hooks to bring the ends of the hooks into contact with the commutator while removing any residue of insulation from the engaging surfaces by ultrasonic oscillations, andultrasonically welding said hook ends to the lamellas of the commutator.
