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.
Claims5
An eccentric-motion motor comprising
- a stator which includes
- a generally annular frame of ferromagnetic material, and
- a plurality of posts projecting generally radially inwardly from the frame, the inner ends of the posts beinq spaced apart from one another so that each post defines a segment of a segmented circular pathway circumscribing an interior space,
- an armature disposed in the interior space to move from segment to segment along the segmented circular pathway, said armature being made of a magnetically attractable material, and
- means for energizing the posts of the stator to cause them to develop electromagnetic forces in a predetermined sequence to attract and cause the armature to roll along the segmented circular pathway.
