Abstract
An eccentric-motion motor for driving a utilization mechanism includes a stator defining a closed surface pathway, an armature composed of a permanent magnet rollably disposed on the closed surface pathway, a series of electromagnetic elements disposed in the stator along the closed surface pathway, circuitry for successively energizing the electromagnetic elements to cause them to attract and/or repel the armature so that it rolls along the closed surface pathway, and a coupler mechanism for coupling the armature to the utilization mechanism so that as the armature is caused to roll, the utilization mechanism is powered by the operation of the motor.
Claims2
An eccentric-motion motor comprising:
- a stator defining first and second spaced-apart, side-by-side annular tracks, said first track being unbroken and made of an electrically conductive material, and said second track comprising a plurality of separated segments and made of an electrically conductive materials,
- a generally cylindrical armature made of a ferromagnetic, electrically conductive material and disposed to roll on the first and second tracks,
- a plurality of electromagnetic elements disposed in the stator generally in series and adjacent at least one of the tracks, each of said elements operating to attract the armature when electrical current is supplied to that element to thereby cause the armature to roll on the tracks toward that element,
- a current source coupled to said first track, and
- a plurality of first conductors, each coupled between a respective segment of the second track and a respective electromagnetic element to carry electrical current from the respective segment to the respective electromagnetic element when the armature is in rolling contact with such segment.
