| Abstract: | This paper reasons about the analytical formulas of the carrying capacity, stiffness, damping and steady region of active magnetic thrust bearings. These formulas are engaged in non dimensional calculation. The relation between the regulative parameters of PD and PID control circuit and the design carrying capacity, stiffness, damping, structral parameter, bias current and the relationships of the mechanical characteristics are gained. It lays a good foundation for further research on dynamical performance of the rotor system of magnetic bearings with the control of multifreedoms. The method of analysis in this paper and some results can be extended to the active magnetic radial bearings. |
