Fig. 7.17:Cross section of a HTSC levitating above a monopole PMG in 3D modeling. The monopole
PMG is composed of two identical PMs. TD is the height of the PMG, whereas TB is the width of
the PM.
HTSC are calculated separately. The MLFs are also recorded and tabulated in Tabs. 7.2
and 7.3.
In order to show the influence of the height and the width of the PM composing
the PMG on the levitation performance of the HTSC, the MLF exerted on the HTSC with
different values of height/width of the PM are shown in Fig. 7.18.
From Fig. 7.18, we can see that the MLF on the HTSC increases with the
height/width of the PM while keeping the width/height constant. When TD changes
from 40 to 60 mm, the width of the PM keeps a constant value of 40 mm. Similarly,
