DISC BLANK FOR PRODUCING COMMUTATOR LAMINATIONS

摘要

The invention relates to a disc blank (18) for producing commutator laminations of a disc commutator and also to a commutator lamination and to a disc commutator formed with such commutator laminations, wherein the disc blank (18) is formed as a multi-layer body and has a shaped carbon body with a continuous first layer and with a contact arrangement which forms a second layer interrupted by transition regions in such a way that the transition regions do not have any contact material.
