WebThe cure was the introduction of 'high resistance brushes' made from graphite (sometimes with added copper). Although the resistance was of the order of tens of milliohms, they were high resistance enough to provide a gradual shift of current from one commutator segment to the next. The term brush remains in use. WebOur carbon brushes enjoy an outstanding reputation in the printing industry across the globe. The materials we use with a high metal content also ensure perfect electric current transfer under the toughest operating conditions. High operational reliability is achieved thanks to a combination with adapted pressure systems.
