    Abstract
    This article presents an analytical micro-vibration model for magnetic bearing reaction wheels (MBRWs) based on a rotordynamics model combined with the active control loop. This model is validated employing a fullyactive Lorentz-type MBRW demonstrator and a multicomponent dynamometer capable of measuring the exported micro-vibrations. The results show an accurate description of the generated vibration by only considering the unbalance forces as excitation.
