We established a 3D coupled model to study the electromagnetic-thermal behaviors of a levitation system containing a bulk high-temperature superconductor (HTS) with a cuboid slot under the nonuniform magnetic field due to the movement of a permanent magnet (PM), analysing the influences of the geometrical parameters of the slot and inclination angle on the electromagnetic-thermal behaviors, giving the dynamic distribution of the global electromagnetic force density in the HTS. The results show that the longer the length of the slot, the smaller the levitation force, and the greater the loss. As its length takes up 7/10 of the HTS diameter, the loss is 4 times that of the HTS without damage. Due to the homodromous induced current appearing near the slot, the maximum guidance force increases with the length. The levitation force decreases with the increase of the slot depth. Its curve near the maximum becomes blunt and the loss increases significantly. As the depth is 3/5-4/5 of t...

运动磁场下具有长方体缝隙的块状超导体的电磁热行为

我们建立了一个3D耦合模型来研究一个悬浮系统的电磁热行为，该悬浮系统包含一个具有长方体缝隙的高温高温超导体（HTS），该高温超导体（HTS）在由于永磁体（PM）的运动而产生的非均匀磁场下进行分析，缝隙几何参数和倾角对电磁热行为的影响，给出了高温超导中整体电磁力密度的动态分布。结果表明，缝隙的长度越长，悬浮力越小，损耗越大。由于其长度占HTS直径的7/10，因此损失是HTS的4倍而没有损坏。由于在缝隙附近出现均匀的感应电流，因此最大引导力随长度增加。悬浮力随着槽深的增加而减小。其接近最大值的曲线变钝，损耗显着增加。由于深度是t的3 / 5-4 / 5
