Electromechanical stiffness and damping coefficients in the repulsive magnetic levitation system

The electromechanical stiffness and damping coefficient matrices for three translational degrees of freedom are derived for the repulsive levitation system consisting of a single superconducting magnet interacting with a finite width sheet guideway. The persistent node (constant flux linkage) is assumed. The results of this study provide the data for stability and ride quality analysis. The methodology can be extended to multi-magnet systems including active damping coils.
