High Speed Rotor Using SMBs Working in Vacuum Chamber

This study is performed to apply superconducting magnetic bearings (SMBs) to a high speed turbine rotor. First, we analyze the system by using 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 (PM) 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.
