Abstract

Front collector for an electrical machine, which equips, in particular, motor vehicles, of the type that includes collector sheets obtained by drawing, in a copper disc, radial grooves that allow a small thickness of material to survive between each of the sheets, the plurality of said sheets being next arranged on an insulating support, made of molded material, by means of anchoring means, characterized in that the copper disc comprises a tubular core and in that before molding the insulating support, the radial grooves, which they form protruding ribs on one of the faces of the disc, they are suppressed, by punching, at the height of the outer diameter of the tubular core in a radial length such that a crown of material of predetermined width is obtained, on the periphery of the disc, which tubular core and which crown are removed in the course of a further machining phase.
