Abstract:
A novel method about two dimension Fourier f requency analysis is proposed in order to obtain high radial rotate precision. The radial rotate precision in the f ront magnetic bearing and rear magnetic bearing are analysed. The results demonst rate that the dy namic unbalance of the shaf t causes the decrease of radial rotate precision. A theory is made to improve the performance in higher speed shaft systems.
