ABSTRACT:
In a fractional horsepower DC motor, wire of an armature coil is connected to a commutator segment by hot forging a tang of the segment onto the wire to grip it. A piece of solder is positioned adjacent the wire and tang during forging to coat the wire during forging and fill in cavities between the wire and tang, thus enhancing the electrical and mechanical connection.
