(Summary description)The brush motor invented in the 19th century is commutated by a rotary switch called commutator/brush on the motor shaft. It consists of a rotating cylinder, divided into multiple metal contact sections on the rotor. These segments are connected to the wire electromagnet windings on the rotor. Two or more fixed contacts called "brushes" are made of a soft conductor similar to graphite and pressed on the commutator. When the rotor rotates, the sliding electrical contacts are brought into contact with the continuous part. The winding provides current. Whenever the rotor rotates 180°, the commutator reverses the direction of the current applied to a given winding, so the magnetic field produces torque in one direction.
