چکیده
The upscale CNC machine is the research object, the magnetic levitation bearing technology which is suitable to AMB spindle and guide are researched. On the basis of the structure and working principle of AMB and the stiffness and damping characteristics, the performance of electromechanical coupling dynamics is studied according to the theory of traditional dynamics and the characteristics of AMB. Then the theoretical calculation and simulation is made with several groups of different electrical parameters as input and the relationship between the controller parameters and the accuracy and stability of AMB feeding guide system, which provides a theoretical reference for achieving the optimal performance of magnetic levitation by adjusting the control parameters.
