velocities of 0.1 to 1.0 mm/s (velocity partition 0.1 mm/s) are also shown and found
to fit well with the profile.
Figure 5.19 shows the stiffness test results of the levitation forces at the sampling
velocity of 1.0 mm/s. Sampling point gap was 1.0 mm, and 61 sampling points were
taken in the measurement range of 95–15 mm.
Figure 5.20 shows the stiffness test results of the guidance forces with the samp-
ling velocity of 1.0 mm/s. The sampling point gap was 1.0 mm, and 61 sampling points
were taken in the measurement range of−30 to 30 mm.
Figure 5.21 shows time-dependent levitation forces at the standard weights of
18.62 N. The sampling point interval was 0.1 s, and 1001 sampling points were acqui-
red at the measurement range of 1–100 s.
The above magnetic levitation properties between the PMs were measured by the
SCML-02 HTS Maglev measurement system. These measurement results validated the
high precision and multi-functionality of the SCML-02.
