Interakcija feromagnetnih in superprevodnih permanentnih magnetov: superprevodna levitacija

 

Superprevodni magnetni ležaji na osnovi visokotemperaturnih superprevodniki bodo nove načine prevoza in logistike v mestih približali stvarnosti. Prednost superprevodne magnetne levitacije je, da je pasivno stabilna brez kakršnega koli elektronskega nadzora, a vseeno generira privlačne in odbojne sile, ki držijo tako mirujoče kot hitro gibajoče se vozilo v stabilni viseči ali stoječi legi. To so izvrstni pogoji za posamično tirno vozilo s kabino za 4 ali 5 potnikov, ki je na voljo na poziv. Ta vozila bodo brez hrupa levitirala nad tiri iz permanentnih magnetov iz redkih zemelj ter prihranila energijo in čas potovanja. Velik korak naprej v tej viziji smo napravili v Dresdnu. Odprli smo največji svetovni raziskovalni in testni laboratorij za transportne sisteme z visokotemperaturnimi superprevodnimi magneti za levitacijo in vodenje v kombinaciji s tirom iz permanentnih magnetov. Vozilo za 2 osebi, opremljeno z linearnim pogonom, brezstičnim dovodom energije, drugim zavornim sistemom ter raznovrstnimi testnimi in merilnimi sistemi vozi po 80 m dolgi ovalni progi. V predavanju bomo opisali načelo superprevodne levitacije s pripetjem pretoka v visokotemperaturnih superprevodnikih in ga eksperimentalno ponazorili z različnimi modelnimi železniškimi sistemi. Predstavili bomo pregled raziskovalnega laboratorija SupraTrans II ter prihodnje smeri razvoja magnetne levitacije in ležajev na osnovi superprevodnikov za avtomatizacijsko tehnologijo, transport in medicinske namene v pogojih povečane težnosti. Spregovorili bomo tudi o superprevodni lebdeči deski, ki jo je nedavno predstavil Lexus. 

Predavanje bo v angleščini.

Lepo vabljeni!

Interaction of Ferromagnetic and Superconducting Permanent Magnets: Superconducting Levitation

 

 

New means of urban transportation and logistics will become realistic with superconducting magnetic bearings using bulk high-temperature superconductors. The advantage of super­con­ducting magnetic levitation is that it is passively stable without any electronic control, but with attracting and repelling forces to suspend a vehicle pendant or standing upright from zero to high speed. These are perfect conditions for a rail-bound, individual transport with cabins for 4 to 5 passengers, requested call by call. They will levitate without noise over a track made of rare-earth permanent magnets, saving energy and travel time. A big step forward in this vision has been made in Dresden. The world largest research and test facility for transport systems using bulk high-temperature superconducting material in the levitation and guidance system, in combination with a permanent magnet track, was put into operation. A vehicle for 2 passengers, equipped with linear drive propulsion, a noncontact energy supply, a second braking system, and various test and measurement systems is running on an 80 m long, oval driveway. In the presentation, the principle of superconducting levitation by flux pinning in high-temperature super­con­ductors will be described and experimentally demonstrated with different model railway systems. Based on this, an over­view of the SupraTrans II research facility and future directions of super­conductivity-based magnetic levitation and bearing for automation technology, transportation, and medical treatment under enhanced gravity will be given. Also the superconducting hoverboard, recently presented by Lexus, will be discussed.

 

Cordially invited!
