ABSTRACT:
In a magnetic bearing system, wherein the gap between relatively moveable elements is controlled by variation of magnetic force therebetween, light is directed from one of the members onto the other member, and reflected back, the reflected light being converted to an electrical signal. The magnetic force between the members is controlled as a direct function of the magnitude of the reflected light. The optical system may include optical fibers for directing the light, and markings may also be provided on the other member to enable determination of relative speed between the members in a further transducing system.
