“…Zhao's lab has a model maglev car on round permanent magnetic tracks with diameter of 5 m. They plan to install a tunnel for it to mimic the low-vacuumed and tunneled high-speed transportation. Yang's work [4] is much earlier in model HTSC maglev cars (Fig. 3) that are very useful in education.…”

“…YBCO bulk superconductor can be widely used for different kinds of applications such as field trapped magnets, magnetic bearing and motors, [1][2][3][4][5][6][7][8][9] due to its high T c , high critical current density (J c ), large levitation force and self-stability levitation. Non-superconducting Y 2 BaCuO y (Y211) and RE 2 Ba 4 CuMO y (REM2411, M=U, Mo, Zr, Bi, Nb, W, etc.)…”

Single domain YBCO bulk superconductors with different additions of ZnO have been successfully fabricated by RE+011 TSIG process with a new solid phase of [(100 − x)(Y 2 O 3 +1.2BaCuO 2 )+xZnO] and a new liquid phase of (Y 2 O 3 +6CuO+10BaCuO 2 ). The effects of ZnO additions on the growth morphology, microstructure, critical temperature (Tc), the levitation force and trapped field of the YBCO bulks have been investigated. It is found that within the range of ZnO additions x = 0-1.0 wt.%, all the samples are of the typical characteristic of single-domain YBCO bulk; the Tc of the samples decreases from 92 K to 80 K when the ZnO addition x increases from x = 0 wt.% to x = 1.0 wt.%; the levitation force and trapped field of the samples firstly increase and then decrease with increase of ZnO additions after going through a maximum, which is closely related with the ZnO addition and the resulting flux pinning force caused by lattice distortion due to the substitution of Zn 2+ for Cu 2+ site in the YBCO crystal; the largest levitation force 36.8 N (77 K, 0.5 T) and trapped field 0.416 T (77 K, 0.5 T) of the samples are obtained when x = 0.1 wt.%, respectively. This result is significantly important and helpful for us to improve the properties of YBCO bulk superconductors.

“…With the development of the high temperature superconductor (HTS), HTS has great potential applications in many engineering fields [4][5][6][7][8]. As one of the most popular applications of the HTS, the HTS magnetic levitation system shows many superior perform-ances in self-stabilization, safety, frictional losses, energy consumption, transportation speed, etc [9][10]. From the viewpoint of the development of maglev vehicles, running tests conducted in air clarified that the pinning-type superconducting magnetic levitation guide with bulk high-T c superconductors is useful as an excellent support system for transportation [11].…”

The super-high speed high temperature superconductor (HTS) maglev evacuated tube transport (ETT) is a promising transport mode for the future. As a key component of the HTS maglev vehicle, the permanent magnet guideways (PMGs) with different geometrical configurations and iron yoke widths are analyzed by finite element method (FEM). The levitation force of a single onboard HTS maglev device over the designed PMG at different field cooling heights (FCH) is measured by magnetic levitation measurement system. Based on the designed PMG and experimental results, a preliminary scheme of subterranean super-high speed HTS maglev ETT is described in this paper. The HTS maglev ETT is mainly composed of an evacuated tube, HTS maglev vehicle, PMG, propulsion system, station, emergency rescue system, etc. In addition, a subterranean tube that consists of foundation tube and vacuum airproof layer is introduced. In order to convert the stress caused by the air pressure difference between inside and outside of the vehicle, a multi-circular vehicle body is designed. The vehicle is driven by a linear motor propulsion system under the control of a ground controlling system. The scheme of long-distance super-high speed passenger transportation is accomplished by the connection of different vehicles.
