Environment and brushes for high-current rotating electrical machinery

摘要

A high-current electrical machine, comprises a stationary and a moving member and at least one current collector brush disposed between the members and in frictional contact with one member; where the brush comprises a plurality of flexurally independent, metal fibers, and where a non-oxidizing gaseous medium containing water vapor, contacts the interface of frictional contact of the brush to provide a lubricating effect.
