Abstract
A brush assembly for an electric motor comprises a brush for making sliding contact with a commutator, the brush being fitted to an end of an elongate resilient electrically conductive brush arm fixed to a brush mounting plate. The brush and brush arm are arranged to ensure that the brush contacts the commutator at a single point in the vicinity of a side face of the brush so that the resilient urgings of the brush arm causing the brush to bear on the commutator surface creates a lateral twist in the elongate brush arm.
