Abstract

A commutator is manufactured by transversaly machining an elongate or cylindrical copper member on one side thereof for providing anchoring elements, whereafter the copper member as cylindrically rolled up is connected with a cast commutator body and is transversely cut for the mutual separation of the commutator elements. The anchoring elements are provided by subjecting the copper member to a plough up action from an undercut sticking and ploughing tool or tool set, whereby raised ribs are produced along the sides of the tool. With this production method the anchor ribs as constituted by compression displaced copper will show a high strength, whereby the method is applicable for the manufacturing of commutators even for high performance requirements.
