Parametric Stability of Microscale Contactless Inductive Suspension with an Electrostatic Control Loop of Stiffness
Abstract
In the article the parametric oscillations of an unreformed disk located in a contactless electromagnetic suspension with an electrostatic loop of the effective control stiffness were investigated analytically. The analytical expressions for the transition curves of the stationary position of the levitated object were obtained based on the asymptotical method of nonlinear dynamics for the areas of the main and secondary parametric resonances. The system parameters were estimated for which the contactless suspension with quasi-zero electromagnetic stiffness is asymptotically stable.
