Abstract

PURPOSE: To manufacture endurable commutators at low cost and simplify manufacturing processes by baking a cylindrical carbon part, plating it, fixing terminals to the plating layer and forming commutator pieces.
CONSTITUTION: A cylindrical carbon part 1 is formed by compression-forming powder carbon, then baked at about 2800°C to graphitize and next plated to form a plating layer 1a on the surface. Next, a doveloped plate 2 consisting of terminals 3 and a connecting part 4 is rounded in a cylindrical form, inserted into the carbon part 1 and fixed to the plating layer 1a. Next, a resin part 6 is formed around the carbon part 1 and the terminals 3 by resin molding or the like and the ends of the terminals 3 are bent to form risers 7. Finally, longitudinal notches 9 are made radially to separate the carbon part 1 and the connecting part 4 and thus commutator pieces 8 are formed.
