    摘要: A direct current motor having an armature axially supported between magnetic pole plates having opposing pairs of pole shoes extending in interdigital parallel opposition with respect to the periphery of the armature between the pole plates adjacent the armature, is energized by direct current through a pair of coils interposed between and connected with the magnetic pole plates. The respective ends of selected pole shoes are connected with pole plates of like polarity magnetic flux and similarly the remaining of pole shoes are connected at their respective ends with pole plates of opposite polarity magnetic flux density. Wiring and electrical current controls connect a DC source to the coils and armature for providing a maximum torque and speed drive shaft with a minimum of ampere drain from the DC source.

    摘要: A rotary electric dynamo machine in which the ripple component in the output occurs at a higher frequency. One half of the pole faces have a nonuniform airgap while the other half have a uniform air gap and cover a noninteger slot distance. The armature has an odd number of slots. Instead of the usual ripple component at the slot frequency, a dynamo constructed as described above, surprisingly, has a predominant ripple component at twice the slot frequency.
