| Abstract |
It is well known that high temperature superconducting (HTS) bulk can levitate stably on a permanent magnet. We have proposed a new linear synchronous motor (LSM) theory which is based on an idea of c...onsidering the pinning force as synchronizing force in using current-carrying- armature-winding instead of permanent magnets. It has been verified experimentally that HTS bulk could be moved successfully along the armature guideway. However, HTS bulk could not produce lift force enough to levitate the HTS bulk ship, which is suspended by the water buoyancy. To generate much stronger lift force, we carry out basic experiments on two-dimensional electromagnetic forces produced in HTS bulk within DC-magnetic-field. As a result, we found a large lift force to be obtained stably at the edges of the electromagnet. This paper presents two-dimensional electromagnetic-force analysis based on finite element method (FEM) simulations of HTS bulk and electromagnet. It is found that the simulated results well agree with the measured forces.show more
