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