摘要：
This paper is performed to apply superconducting magnetic bearings (SMBs) to a high-speed turbine rotor. First, we analyze the system by using the finite-element method and design the structure whose vibrations are suppressed well. Then, we have made an experimental setup using the theoretical result. The experimental setup consists of two SMBs, a permanent magnet motor and a rotor with many turbine blades. We perform some experiments using this experimental setup in a vacuum chamber. In this paper, we discuss the dynamic characteristics of the spinning rotor with many turbine blades.
