  • Electric motor
    Patent number: 4291248
    Abstract: An electric motor having exceedingly high efficiencies includes three induction coils equally disposed about a circular path, a toroidally-shaped armature is disposed within the induction coils. The armature has a non-magnetic segment placed therein, thereby creating a pair of poles. Gear means are disposed within the armature and are operatively coupled thereto to provide mechanical output energy. The motor is driven by sequentially connecting a D.C. voltage to each of the three induction coils for a prescribed time.
