Abstract
The small motor has a rotor with commutator segments and a stator supporting the pivoted arms that hold the brushes. Each arm is spring loaded. Two hooks ensure that the arms remain within their required pivot limits. Each hook engages at one end around the pivot of the arm and locates at the other inside a hole in the frame. The helical springs that load the arms engage at one end in the frame and at the other end along the arm. the brushes are approximately at right angles to the axes of the arms and are diametrically opposite one another.
