Abstract A torque/force transfer apparatus which includes an annular ring having tein permanent first magnets side by side about the interior of the ring. The first magnets are arranged so as to alternate in polar orientation to present an inside circumference of alternating north and south magnetic poles. A cylindrical central member has therein permanent second magnets side by side about the exterior of the central member. The second magnets are arranged so as to alternate in polar orientation to present an outside circumference of alternating north and south magnetic poles. A strut assembly is pivotally attached to a center of a side of the central member and has arms extending radially outwardly from the central member center and is provided with planetary members rotatably connected each to one of the arms. The planetary members each have therein permanent third magnets side by side about the exterior of the planetary member, the third magnets being arranged so as to alternate in polar orientation to present an outside circumference of alternating north and south magnetic poles. Each of the planetary members substantially bridges an annulus defined by the ring inside circumference and the central member outside circumference, whereby rotation of the central member causes, by magnetic flux, rotation of the planetary members which cause, by magnetic flux, rotation of the ring.

Claim 1
Independent Claim
227 words
A torque/force transfer apparatus comprising: a rigid annular ring having therein permanent first magnets side by side about the interior of said ring, said first magnets being arranged so as to alternate in polar orientation to present an inside circumference of alternating north and south magnetic poles; a cylindrical central member having therein permanent second magnets side by side about the exterior of said member, said second magnets being arranged so as to alternate in polar orientation to present an outside circumference of alternating north and south magnetic poles; a strut assembly pivotally attached to a center of a side of said central member and having arms extending radially outwardly from said central member center each of said arms being individually pivotally attached to said central member; planetary members rotatably connected each to one of said arms, each of said planetary members having therein permanent third magnets side by side about the exterior of the planetary member, said third magnets being arranged so as to alternate in polar orientation to present on outside circumference of alternating north and south magnetic poles, each of said planetary members substantially bridging an annulus defined by said ring inside circumference and said central member outside circumference; and whereby rotation of said central member causes, by magnetic flux, rotation of said planetary members which cause, by magnetic flux, rotation of said ring.
Claim 2
Dependent Claim
227 words
A torque/force transfer apparatus comprising: a rigid annular ring having therein permanent first magnets side by side about the interior of said ring, said first magnets being arranged so as to alternate in polar orientation to present an inside circumference of alternating north and south magnetic poles; a cylindrical central member having therein permanent second magnets side by side about the exterior of said member, said second magnets being arranged so as to alternate in polar orientation to present an outside circumference of alternating north and south magnetic poles; a strut assembly pivotally attached to a center of a side of said central member and having arms extending radially outwardly from said central member center each of said arms being individually pivotally attached to said central member; planetary members rotatably connected each to one of said arms, each of said planetary members having therein permanent third magnets side by side about the exterior of the planetary member, said third magnets being arranged so as to alternate in polar orientation to present on outside circumference of alternating north and south magnetic poles, each of said planetary members substantially bridging an annulus defined by said ring inside circumference and said central member outside circumference; and whereby rotation of said central member causes, by magnetic flux, rotation of said planetary members which cause, by magnetic flux, rotation of said ring.
Claim 3
Dependent Claim
