置。 A three-electromagnetic magnetic bearing device comprising a rotating shaft or rotor, and three electromagnets arranged around and facing the rotating shaft or rotor to apply an attractive electromagnetic force to the rotating shaft or rotor, Three displacement detectors are provided to detect the gap between each of the electromagnets and the rotating shaft or rotor, and the displacement in the x and y directions perpendicular to the rotating shaft or rotor is determined from the detection signals of the three displacement detectors. A magnetic bearing device comprising: a command signal calculation circuit for a force that is calculated and acts to reduce the displacement to zero; and a calculation circuit that creates excitation command signals for the three electromagnets from the output signal of the calculation circuit. .
