Recent Developments in Light Duty Cranking Motors

Several new features have been developed for light-duty cranking motors which reduce costs, improve manufacturing productivity, and improve reliability. These include a face type commutator which combines the function of current collection and connection to the armature windings, fully insulated plastic molded brushgear, a single field coil to replace the four coils of a conventional four pole field system, a five roller extruded roller clutch, and a solenoid with a two part sintered iron body.
