Lin, G. Ma, D. Jiang, J. Wang, S. Wang] This paper focuses on the magnetic field inhomogeneity at the rail gap due to five kinds of position deviations between two segments of permanent magnet guideway (PMG). PMG model is built by the finite element analysis software, and effectiveness of the model is proven by comparing the actual magnetic field with the calculated value. The influence of the magnetic field by the gap, horizontal displacement and vertical displacement was investigated. Kinetic characteristics of HTS maglev when it passes the rail gap are studied. The change of magnetic field at the rail gap is also studied in these cases: one PMG rotates relative to another PMG and the gap is not perpendicular to the direction of PMG. It is found that magnetic force between two PMGs will enlarge the position deviations. Finally, the methods are introduced for improving the homogeneity of magnetic field of PMG and then reducing the magnetic loss due to magnetic field inhomogeneity.
