300HP급 초고속 전동기용 회전체의 동력학적 해석 및 설계

Design and Dynamic Analysis of Rotor for 300HP Class Super High-Speed Motor

  • 발행 : 2007.04.19


The Super High-Speed Motor is a turbo machine which operates at high speed, so air foil bearings suit their purpose as bearing elements. The rotordynamic stability was predicted using the numerical analysis of air foil bearings. From this study, the stability of rotor of the Super High-Speed Motor was confirmed by campbell diagram and logarithmic decrement.
