on-board HTS Maglev equipment outside size is 150× 516 ×168 mm and is composed
of a rectangle-shape liquid nitrogen vessel and 43 pieces of YBaCuO bulks. The vessel
bottom has a thickness of only 3 mm. The linear motor acceleration is 1 m/s^2. Here are
the key observations from this HTS Maglev system:
- In order to minimize the distance between PMG and HTS bulks and increase
HTS Maglev efficiency, we developed the innovative rectangular liquid nitrogen
cryogenic vessel with a 3-mm-thin bottom wall, which made HTS Maglev vehicle
feasible.
