This article deals with the magnetic resistance that arises in the cooled high temperature superconductor (HTS) bulk, dynamically interacting with a frequently perturbed flux of magnetic track employing homopolar permanent magnets (PM) arranged within an “U” shaped loose iron core. The influence of flux perturbation on the magneto-dynamic maglev performance of HTS bulk is studied and tested by means of an experimental ring model device employing the same passive YBaCuO structure interacting with a magnetic track field differently perturbed by several iron plates radially and frequently distributed on the circular track. This experimental model device reproduces, by analogy, the magneto-dynamic behavior of a vehicle with HTS onboard riding above an uneven magnetic guideway. Finally, magnetic resistances and lift forces have been tested and the results are compared and discussed.

Abstract

This article deals with the magnetic resistance that arises in the cooled high temperature superconductor (HTS) bulk, dynamically interacting with a frequently perturbed flux of magnetic track employing homopolar permanent magnets (PM) arranged within an “U” shaped loose iron core. The influence of flux perturbation on the magneto-dynamic maglev performance of HTS bulk is studied and tested by means of an experimental ring model device employing the same passive YBaCuO structure interacting with a magnetic track field differently perturbed by several iron plates radially and frequently distributed on the circular track. This experimental model device reproduces, by analogy, the magneto-dynamic behavior of a vehicle with HTS onboard riding above an uneven magnetic guideway. Finally, magnetic resistances and lift forces have been tested and the results are compared and discussed.
