COMMUTATOR FOR FLAT MOTOR AND METHOD OF MAKING SAME

摘要

The invention provides a commutator for a flat motor which includes fan-shaped brush contact pieces (2) and connection pieces (3) raised up from said brush contact pieces and electrically integral therewith wherein a plurality of segments (4) made of conductive material are arranged spaced in an annular pattern in such a way that said connection pieces are positioned at an inner edge, said segments are insulated from each other by an insulator material member (5), top ends of said connection pieces are bent to an inverted U-shape, their free ends (3b) are buried in said insulator material, and connection wires of an armature winding may be pushed into the slits (6) made at the top ends of said connection pieces so as to connect the segments with the armature winding. The invention also provides a method of forming such an armature.
