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.
Claims3
An eccentric-motion motor comprising
- a stator defining a continuous closed surface pathway,
- a plurality of elongate permanent magnets disposed in an array at the closed surface, the magnets having enlarged end pieces being disposed to form the continuous closed surface pathway,
- an armature comprising a bar of ferromagnetic material disposed to roll on the closed surface pathway,
- an electrical conductor for receiving electrical current and helically spaced out of contact with and about the armature and out of electrical contact with the stator, said conductor suspended through electrically insulated apertures in the stator, the apertures having electrically insulated sleeves, the sleeves having an outer portion in contact with the aperture and an inner portion in contact with and compressed about leads of the conductor, and
- means for supplying electrical current of selectively alternatable polarity to the conductor to successively cause the armature to switch polarities and thereby be attracted toward and repelled from the permanent magnets to thus roll on the pathway.
