Abstract:
An electromagnetic bearing apparatus having five degrees of freedom includes two radial magnetic bearings. Each of the radial bearings consists of two pairs of electromagnets. The electromagnets of one pair are arranged opposite one another around a rotating shaft, and the other pair is arranged in the same perpendicular plane as the preceding pair. The pairs of electromagnets in the two radial bearings are respectively controlled to stabilize the rotating shaft to obtain automatic regulation, in which deviation of the shaft in a radial sense is compensated according to the component of shaft radial deviation and deviating velocity and the gyro-effect which will be caused by the perpendicular compensating torque to compensate the future rotation in the perpendicular component.
