Slip-ring configuration in electric motors and generators, slip-ring body and method for retooling slip-ring bodies

摘要

A slip-ring configuration for electric motors and generators is provided, in which brushes made of carbon materials and slip rings of a slip-ring body are electrically conductively connected to each other. The slip rings include metallic rings of standard construction as a slip-ring base and an electrically conductive sliding layer made of a graphite material. The sliding layer has a thickness which amounts to a maximum of 11% of a radius of the slip ring and is electrically conductively fastened to the periphery of the metallic slip-ring base by gluing. A method for retooling slip-ring bodies having metallic slip rings includes machining the metallic slip rings and gluing on a sliding layer.
