Although the AMB technology has important advantages mainly due to lack of mechanical friction, its nonlinear nature complicates design and control such systems. In this work, analysis an system, MBC500 Rotor Dynamics from Launchpoint Technologies, is presented. This based on harmonic domain linearization system around a stationary solution, leading LTV model for each rotating speed. The response appears at high speeds, large oscillations introduced by shaft unbalance. Using presented...
