Abstract

The levitation force of a bulk high temperature superconductor (HTSC) over Halbach permanent magnet guideways (PMG) with different cross-section configuration is studied by numerical method. The Halbach PMG is composed of three host permanent magnets (HPMs) and two slave permanent magnets (SPMs). One cylindrical bulk HTSC with a diameter of 30 mm and height of 15 mm is used. The 3D-modeling is formulated by the H-method. The numerical resolving codes are practiced using finite element method (FEM). The E-J power law is used to describe the electric current nonlinear characteristics of bulk HTSC. By the method, the influence of the cross-section physical dimensions of Halbach PMG on the levitation forces of bulk HTSC levitated above the PMG is studied. The simulation results show that increasing the width of SPM (\(W_\mathrm{SPM})\) can enhance the bulk HTSC levitation performance immediately under the condition of keeping the ratio of \(W_\mathrm{HPM}\) (\(W_\mathrm{HPM}\) : the width of HPM) to \(W_\mathrm{SPM}\) between 1.6 and 1.8, the ratio of td (the height of the PMG) to \(W_\mathrm{HPM }\)between 1.2 and 1.4. By the method, the bulk HTSC better levitation performance can be expected.
