PROBLEM TO BE SOLVED: To provide a superconductive magnetic bearing that can suppress magnetic field change to a level at which eddy current loss (Joule heat generation) exerts substantially no influence on a cooling plate of a stator coil even if the magnetic field change occurs owing to displacement of the axis of rotation of a rotor and up/down vibrations, and also can minimize a temperature rise of the coil by constituting a cooling member such that a copper-made cooling plate of a stator (superconducting) coil of the superconducting magnetic bearing has pipes 3A, 3B, made of highly heat conductive members of copper, etc., of about 1 mm in diameter of a simple plate material constitution of 2 mm in plate thickness, regularly arranged at intervals.SOLUTION: A superconducting magnetic bearing of a superconducting flywheel power storage system has a cooling constitution of a superconducting coil of a stator 1 such that pipes 3A, 3B made of highly heat conductive members are regularly arranged at intervals and plainly woven with an electric insulating material 3C.SELECTED DRAWING: Figure 3 |
