| Abstract: | To overcome the defects of the present hybrid magnetic bearing,a novel AC hybrid magnetic bearing as a supporting part of high-speed electric spindle is proposed in this paper.The permanent magnet is implemented to generate a constant bias flux whereas coils generate the control flux.The structure and the working principle of the magnetic bearing is introduced.Lastly with the consideration of gyroscopic coupling,the 4-DOF models of grid and flexible rotor for high-speed electric spindle are built on the basis of Matlab/Simulink. |
