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
