Abstract:
A planar carbon segment commutator, comprising:a commutator base of insulating material, the base having a rotational axis, front and rear surfaces extending, at least in part, transversely to the rotational axis, and a plurality of first apertures extending through the base; a plurality of commutator terminals, each of the commutator terminals comprising: a terminal portion having a cutting edge for cutting insulation on a connector portion of a winding and a slot which, in use, straddles and grips said connector portion, and a contact portion extending through one of said first apertures in the base and being bent at an angle which is substantially perpendicular to the terminal portion so as to lie against or in close proximity to the front surface of the base; and a plurality of carbon commutator segments formed on the front surface of the base and over the contact portions, respectively, of the terminals.
