Abstract

An experimental ring model device employing a high critical temperature superconductor (HTCS) short \“runner” above the circular iron-homopolar magnetic guideway was designed and manufactured. The device simulates, by analogy, the electromagnetic behaviour of a magnetically levitated vehicle, with passive short superconductor \“runners” on board, riding along a magnetic track. In the wide range of work conditions magnetic levitation experiments were conducted and lift and drag forces were measured. Numerical analyses by twodimensional finite element parametric models were carried out; the results are presented in terms of forces and flux density distribution. Keywords: high temperature superconductor, permanent magnet, levitation, modelling.
