A compact assembly of two magnetic couplers for coupling two coaxial angular shaft movements through a vacuum barrier. Each coupler includes two concentric rings of radially oriented magnets, arranged to provide magnetic coupling in a radial direction between corresponding magnets in the rings. A relatively large number of magnets in each ring ensures stiff coupling between rings, but unwanted circumferential coupling between adjacent magnets in each ring is minimized by the presence of a flux ring associated with each ring of magnets. The flux rings pro...
A dual magnetic coupler mechanism, comprising: a first coupler, having a primary ring of magnets and a secondary ring of magnets, said secondary ring concentric with and generally coplanar with the primary ring, each ring being mounted for rotation about a common axis, and each ring containing a plurality of radially oriented magnets, wherein magnets in the primary ring are magnetically coupled, in a radial sense, with corresponding magnets in the secondary ring; a second coupler similar to the first coupler, also having a primary ring of magnets and a s...
