MAGNETIC POLE SHOE DC MOTOR ASSEMBLY

摘要

A direct current motor (10) having an armature (28) axially supported between magnetic pole plates (15-16, 17-18, 19-20) having opposing pairs of pole shoes (50-52; 60-62) 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 (24, 25) 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 (69) and electrical current controls (68) connect a DC source (B) to the coils and armature for providing a maximum torque and drive shaft speed with a minimum of ampere drain from the DC source.
