ABSTRACT:
A radial magnetic bearing system for use in turbomachinery, machine tools and so forth is disclosed. A rotary yoke made of a magnetic material is rigidly secured to a rotary shaft, and an electromagnet stator is rigidly secured to a casing. The stator is arranged to generate magnetic attraction forces radially at equi-angular spacings of 120.degree. within a plane perpendicular to the axis of the rotary shaft. Three displacement sensors are arranged such that each sensor measures displacement of the rotary shaft with respect to the casing in the direction of one of the three magnetic attraction forces, thus controlling the level of each magnetic attraction force.
