Abstract

PURPOSE: To produce a perfectly-bearing-frictionless motor of simple mechanism by composing it of a magnetic ring core, magnetized with both flanks differing in polarity, and a fixed magnetic column core and then by turning the magnetic ring core through the induction of an AC magnetic field while supporting the magnetic ring core by repulsion between the magnetic column core and magnetic ring core.
CONSTITUTION: Flanks of magnetic ring core 1 differ in polarity, and both ends of magnetic column core 2 also differ in polarity. Magnetic column core 2, penetrating magnetic ring core 1, is arranged with both ends fixed to support frame 3 while magnetic poles are equalized in direction. Rotor iron core 4 is fixed on the inside circumferential surface of magnetic ring core 1, and stater iron core 5 on the circumferential surface of magnetic column core 2. When a stator winding provided to iron core 5 is excited to provide a revolving magnetic field, turing force is generated across rotor iron core 4 and magnetic ring core 1 rotates on a holding axis as a rotation axis by the repulsion of magnetic column core 2. Since no frictional force operates, the magnetic ring core can turn at a high speed and this motor can be miniaturized on the whole.
