Abstract
In a magnetic bearing in which a first part (1, 20) is mounted magnetically relative to a second part (3, 10) and the second part (3, 10) has a Type II superconducting material (2) containing an anisotropic crystal or a plurality of grains formed of this anisotropic crystal, this crystal being anisotropic in that the superconducting current flows in current-carrying planes, the first part (1, 20) has a configuration of magnets (1; 6, 7, 8; 11, 12, 13, 14; 30, 31, 32, 34; 50, 51, 52, 53) with which the superconducting material (2) interacts, and the crystal itself or the crystal in the plurality of grains faces the first part (1, 20) with the normals on the current-carrying planes (a-b).
Claims10
A magnetic bearing comprising
- a Type II superconducting material (2) which is a melt-textured multigrain material and which is made of or contains a XxBa2Cu3O(7-δ) compound with X being a rare earth metal from the group Y, Sm, Nd, Tb, and with 1≦x≦1.6 and 0.01≦δ≦0.10,
- a first part (1, 20) and a second part (3, 10), wherein said first part (1, 20) has permanent-magnetic characteristics at least in some areas thereof and is mounted magnetically relative to said second part (3, 10), wherein said second part (3, 10) comprises the Type II superconducting material (2) and wherein said first part is connected with a polygon mirror (40).
