Brush ring for electric motor e.g. for machine tools, has current-conducting contact element consisting of fine, current-conducting fibres, preferably carbon fibres, fixed in current-conducting bearer element

摘要

The brush ring (3) has a current conducting contact element consisting of a number of fine, current-conducting fibres, preferably carbon fibres, fixed in a current-conducting bearer element (2). The bearer element with the brush rung is mounted on the rotor (6) or stator of the electric motor in a suitable manner.
