ABSTRACT:
An electric motor has a can-like casing and an end cap. Brushgear is mounted on a frame prior to insertion into the motor. The frame holds the brushes of the brush gear away from a commutator of the motor by means of resilient arms which engage the brush gear. As the frame is inserted into the motor the arms come against a post which bends the arms to disengage them from the brush arms so that the brushes settle onto the commutator.
