Permanent-Magnet Meissner Bearing
Author and Affiliation:
Robertson, Glen A.(NASA Marshall Space Flight Center, Huntsville, AL.)
Abstract: Permanent-magnet meissner bearing features inherently stable, self-centering conical configuration. Bearing made stiffer or less stiff by selection of magnets, springs, and spring adjustments. Cylindrical permanent magnets with axial magnetization stacked coaxially on rotor with alternating polarity. Typically, rare-earth magnets used. Magnets machined and fitted together to form conical outer surface.
