<P>PROBLEM TO BE SOLVED: To provide a magnetic bearing and a stabilization method of the magnetic bearing by which the bearing capacity does not vary regardless of the temporal deterioration of the magnetic levitation characteristic and the rotational loss of a high temperature superconducting bulk body in the magnetic bearing using the high temperature superconducting bulk body. <P>SOLUTION: The magnetic bearing using the high temperature superconducting bulk body is provided with, the high temperature superconducting bulk body 4 which is built in a rotating shaft 3, an electromagnet 5 as a magnetism generator which is arranged on a fixed side so as to apply electromagnetic force as levitation force or guide force on the high temperature superconducting bulk body 4, and the electromagnetic force adjustment means to adjust the electromagnetic force which is generated by the electromagnet 5. <P>COPYRIGHT: (C)2009,JPO&INPIT |
