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. Webto switch current in the motor windings. Instead, the commutation of the windings of a BDC motor is done mechanically. A segmented copper sleeve, called a commutator, resides on the axle of a BDC motor. As the motor turns, carbon brushes slide over the commutator, coming in contact with different segments of the commutator.
