“…10,11 Traditionally, superconducting bulks are used in the production of high-speed bearings or maglev trains, but nowadays they are showing great potential in the growing field of energy storage, where they can be used to manufacture levitating flywheels. 12,13 Single-domain superconducting bulks can be produced by various methods. The two most common methods are topseeded melt growth (TSMG) and top-seeded infiltration growth (TSIG).…”

“…In MAGLEV trains the magnets are inserted in the guideways and the superconductors are in cryostats located below the cars [6]. A parameter important for the application is the distance between both components during FC [7,8]. The larger the FC distance, the larger the levitation force but the weaker the system stability.…”

Increased levitation force in a stable hybrid superconducting magnetic levitation set-up

We present results obtained with an original hybrid set-up permitting to increase strongly the levitation force of Superconducting Magnetic Levitating (SML) systems. We compare levitation force measurements carried out with this set-up to measurements carried out with a conventional one. We investigate the stability of the proposed system by measuring the lateral (or restoring) force. We show how to calculate the measured levitation and lateral forces from: i) those measured in the conventional configuration and ii) the repulsive force between the magnets included in the system. We discuss the conditions of stability of the proposed system as well as the consequences that its introduction could have on the future of SML MAGLEV trains.

“…Due to the potential applications like energy storage systems [12][13][14], levitating vehicles [15][16][17][18][19] high-speed bearings [20,21], etc., this subject has become of great interest in the last three decades. The force measurement is done by varying the distance HTS-PM and therefore many types of measurement systems have been designed to measure the force in one, two or three spatial dimensions [22][23][24]. Important characteristics of the superconductors like critical currents, magnetization, etc., can be deduced from these measurements [25,26].…”

The interaction forces, attraction (suspension) and repulsion (levitation) between a permanent magnet and different bulk Yttrium-based superconductors were carried out with an automatic system developed in our group, which is reproducible, reliable and low cost. Two superconducting samples of YBa 2 Cu 3 O 7−δ (YBCO) prepared by solid-state reaction method (S) and by the melt-textured growth method (MTG) were used. Both samples were characterized by XRD technique and presented the characteristic peaks and intensity relations of the YBCO-123 superconducting phase. Oxygen deficiencies δ > 0,15 and δ < 0,10 for the S and MTG samples respectively, were observed. Both samples displayed different hysteresis behavior in the Force (F ) vs. Distance (z) measurements when they were field cooled (FC) and zero field cooled (ZFC). This behavior agrees with hysteresis loops observed in magnetization measurements. Both levitation and suspension phenomena were observed in the MTG sample with large hysteresis loops of the force. On the contrary, the S sample with small hysteresis loops did not show a suspension force, only displayed a slight levitation force.
