Commutators and brushes work in motors to transfer current to the rotor. The commutator is a segmented, cylindrical metal part attached to the rotor, which acts as a switch to direct current through the motor windings. Brushes, made of conductive materials like carbon, are pressed against the commutator and transmit current to the rotor windings.
