| 内容記述 | Magnetic suspensions for spacecraft attitude control flywheels have such advantages as lower friction/stiction torque, higher reliability and longer life. It is considered that they will be widely used in the near future. This paper presents an analytical estimation method of the axial unbalance stiffness and radial stiffness, of a flywheel rotor, suspended by an axially controlled and radially passive, magnetic bearing. The axial unbalance stiffness is calculated by the utilization of equivalent electric circuits, in which magnetic permeances at air gaps are estimated, using the Roters’method. In the case of the radial stiffness calculation, however, it turns out that this method cannot be easily applied. Therefore, the Laplace equation is numerically solved to yield a potential function, and then the magnetic lines of force are estimated by solving another set of ordinary differential equations. From these results, the radial stiffness is calculated, by integrating the forces along the given boundary. The validity of thse methods is confirmed by the measured values of a laboratory modeled, magnetic suspension. | |||||||||
