摘要：
Superconductors, especially high Te ones, are the most attractive materials to design stable and fully passive magnetic suspensions which have to control five degrees of freedom, The hybrid superconducting magnetic suspensions present high performances and a simple cooling mode?, They consist of a permanent magnet bearing, stabilized by a suitable magnet - superconductor structure. Several designs are given and compared In terms of forces and stiffnesses. The design of the magnet bearing plays an important part. The superconducting magnetic bearing participates less in levitation but must provide a high stabilising stiffness. Tills is achieved by the magnet configuration, a good material in term of critical current density and field cooling. A hybrid superconducting suspension for a flywheel is presented, This system consists of a magnet thrust bearing stabilised by superconductors interacting with an alternating polarity magnet structure. First tests and results are reported. Superconducting materials art: magnetically melt-textured YBaCuO.
