Method of producing a flat commutator and a flat commutator produced according to said method

A method for producing a flat commutator comprising the steps of:

• forming a hub body from insulating molding compound,
• molding said hub body onto a conductor blank provided with radial grooves and filling said radial grooves with molding compound to form a composite part defined by said hub body and conductor blank,
• machining said composite pan by chip-removing tools on an end face of the conductor blank turned away from the hub body such that an annular inner fixation ridge made of molding compound remains on an end face of said composite part, said annular inner fixation ridge having a tapered outer edge that decreases in a machining direction,
• adhesively bonding an annular carbon disk on the machined end face of the composite part to form a commutator blank,
• subdividing said annular carbon disk into carbon segments by cutting into said molding compound that fills the radial grooves, and
• subdividing said conductor blank into conductor segments,
• whereby electrically conductive connections are established between said annular carbon disk and said conductor segments.
