In a three-axis control magnetic bearing that actively controls and constrains the remaining two degrees of freedom and passively constrains the remaining two degrees of freedom, an adjustment weight is provided on the rotating shaft or rotating body to ensure that the center of gravity of the rotating shaft or rotating body is the center of gravity of the radial magnetic bearing. A magnetic bearing device characterized by being located at the center.
