This paper presents the design and experiment of a magnetic levitation system conceived to achieve simultaneously both stable magnetically lift and guidance forces for practical transportation applications. The work principle is based on the partial Meissner effect of high critical temperature superconductor monoliths that produces a repulsive force against a static magnetic field of guideway. The proposed system utilises an “U” shaped iron-magnetic guideway within three sets of Nd-Fe-B permanent magnets interacting with cooled YBCO “runner”. A two-dimensional finite element parametric model of system has been carried out and tuned starting from the experimental data of tests conducted by means a ring model device. Performance levels have been evaluated analysing the system in a wide range of geometrical configurations and work conditions.

Abstract
This paper presents the design and experiment of a magnetic levitation system conceived to achieve simultaneously both stable magnetically lift and guidance forces for practical transportation applications. The work principle is based on the partial Meissner effect of high critical temperature superconductor monoliths that produces a repulsive force against a static magnetic field of guideway. The proposed system utilises an “U” shaped iron-magnetic guideway within three sets of Nd-Fe-B permanent magnets interacting with cooled YBCO “runner”. A two-dimensional finite element parametric model of system has been carried out and tuned starting from the experimental data of tests conducted by means a ring model device. Performance levels have been evaluated analysing the system in a wide range of geometrical configurations and work conditions.Pubblicazioni consigliate
