Abstract
We have designed and constructed a new type of active-maglev system using YBCO bulk and two electromagnets and have demonstrated that levitation height was remarkably improved by continuous levitation. In the active-maglev system, however, the upper and lower coils differed in the coil size and an iron plate beneath the lower coil was used to enhance the magnetic field around the bulk. Considering the real application to maglev transporter in the axial direction, we must realize continuous levitation using a larger number of electromagnets without such the iron plate and enable the levitation height to control freely. In this paper, we demonstrate continuous levitation with controlling the levitation height using three and five electromagnets systems and investigate electromagnetic behavior within the bulk using a FEM computer program.
