Abstract
A bearing structure has one or two (figs 2, 5) pairs of axially spaced permanent magnetic bearings 3, 4 for radially supporting a rotor 1 at two supporting points in a non-contact manner. Thrust forces F1, F2 of each magnetic bearing in a pair act in opposite axial directions and a pivot 5a on an axis 7 of the rotor 1 bears a shaft end 5b of the rotor 1 when the shaft end 5b is displaced in an axial direction from the neutral position where all thrust forces acting on the rotor balance. The magnetic bearings 3, 4 may attract or repel (figs 4-6) and be orientated axially or radially (figs 4-6) of the rotor 1. To cope with excessive rotor displacements in both axial directions, a further stop 6 (8 fig 4) or second pivot (figs 7, 8) may be used. Stop 6 may also space the magnets 4a, 4b to prevent sticking. Two pairs of magnetic bearings may be concentric (fig 2). The rotor may be for a motor, fan or polygonal mirror.
