146 Ë 5 HTS Maglev experimental methods and set-up
The general or standard test equipment can only be used for static or low speed
test, and are incapable of performing the test for a HTS Maglev bearing under heavy
load and high speed. In order to study the effects of the dynamic loss of the HTS bulk in
high-speed bearing, and also to investigate HTS Maglev bearing and flywheel energy
storage technology, a HTS Maglev bearing measurement system was successfully
designed and developed in Beijing Century Superconductivity Company limited, from
2011 to 2014. Figure 5.39 shows the three-dimensional design of main body for the
HTS Maglev bearing measurement system. Figure 5.40 is the HTS Maglev bearing
measurement system and its supporting units.
