An Evaluation of Levitation Property in HTSC Magnetic Bearing Device Including Ferromagnetic Materials

摘要

We improved the conventional numerical methods to simulate the levitation property of HTSC energy storage flywheel systems by considering the effect of ferromagnetic materials. The validity of our new method was confirmed by comparing with the experimental results. By using this new method, we can quantitatively evaluate the effect of ferromagnetic materials on the levitation property and can optimize the design of the flywheel system more precisely.
