ABSTRACT:
A magnetic bearing assembly for levitating a movable member in either rotation or linear translation comprises a three-loop magnetic circuit in which permanent magnets establish a quiescent or fixed flux across four magnetic gaps arranged to provide restoring forces transverse to the direction of gap flux; the resulting inherent instability in the longitudinal direction is overcome by an electric feedback control system which supplies control currents in a pair of coils associated with the magnetic gaps for modulating the permanent magnetic flux therein and thereby provides stabilizing longitudinal magnetic forces. The configuration may be generalized by simple extension to a (2n + 1) loop magnetic circuit with (n + 1) coils.
