The Influence of Excitation Frequeney on Magnetic Levitation Systems with a High-fl Superconductor

Abstract

In this paper we present a numerical analysis of dynamic features of the levitation system generated by an interaction between a levitated permanent magnet (pM) and abigh-Z" superconductor (HTSC) excited by an oscillatory extemal source. The obtained results show that the value of the frequency (,fa"") of the pM displacement in the case of the levitation system generated by an interaction between a levitated PM and a Iixed HTSC is equal at fhe resonance frequency (fir) ofthe levitation system generated by an in_ teraction between a levitated pM and HTS excited by an os_ cillatory extemal source and the resonance frequency (/fg) is mainly dependent upon the cooling position (1g andthe mass of the PM. The numerical probtem in this paper is solved by using the control volume method (CVM).
