Abstract
There is provided a flat type commutator which secures fixing of carbon (graphite) commutator pieces to both metal plate with terminals attached thereto for connecting winding and electrically insulating support, and which can be manufactured easily and at a low manufacturing cost. A flat type commutator with the brush slide-contact surface thereof being perpendicular to the axial direction of a rotor, wherein a plurality of commutator pieces 3 mutually isolated by slits 4 are directly fixed to an electrically insulating support 1, and a metal plate 5 for connecting said commutator pieces, each having terminals 6 for connecting windings is fixed on the outer peripheral surface of said each commutator piece 3 which is in parallel with the axial direction of the rotor. In the manufacture of this flat type commutator, there is simutaneously done the formation of the commutator piece 3 and fixing of the commutator piece 3 to the electrically insulating support 1 and the metal plate 5 for connecting the commutator piece.
