摘要

An object of the present invention is to provide an apparatus for controlling the contact pressure of an object supported by the magnetic bearing using a magnetic bearing, for example, an inflating pressure control device, an inflating pressure control method, an object contact parameter control method, And an object alignment control device. To this end, the present invention provides a magnetic bearing device comprising: a magnetic bearing unit disposed at both ends of a roller unit for pressing a contact object and for supporting the roller unit in a noncontact manner; A first calculation unit that is connected to the magnetic bearing unit and calculates a bearing support force by the magnetic bearing unit; and a control unit that compares the bearing support force with a reference force to which the roller unit should press the contact object, A second calculation unit for determining whether a difference value between the roller unit and the roller unit is included in an allowable range, A control unit having a third calculation unit for calculating a current value; And an electric current applying unit for applying the electric current value to the magnetic bearing unit, an input pressure control method, an object contact parameter control method, an object position alignment control method, and an object position alignment control apparatus using magnetic bearings do.
