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.
Claims7
An electromechanical energy conversion device comprising, in combination:
- (a) housing means;
- (b) three induction coils equally disposed about a circular path and affixed to said housing means forming a stator;
- (c) toroidally-shaped armature means disposed within said induction coils, said armature means including only one permanent magnet and a segment of non-magnetic material, said non-magnetic material comprising 60 degrees of said toroid with said permanent magnet comprising 300 degrees of said toroid;
- (d) gear means connected to said armature means by equally spaced rotatable members in contact therewith, said gear means including an output shaft operatively coupled thereto;
- and
- (e) timing and distribution means connected to each of said coils for a predetermined time period during each cycle.
