  • Patent number: 5365134
    Abstract: A direct current motor having an armature supported between magnetic pole plates having pairs of dual pole shoes extending between the plates in diametric opposition with respect to the periphery of the armature is energized by direct current through a pair of iron coil cores at opposite sides of the armature and connected with the magnetic pole plates. In other embodiments, the magnetic flux pattern facing the armature is longitudinally divided by a groove in the respective pole of the pairs of pole shoes facing the armature. Wiring and electrical current controls connect a DC source to the coils and armature for operating the armature and providing a selected torque with a minimum of ampere drain from the DC source.
