? 2022 Elsevier LtdFor the hybrid magnetically suspended flywheel (MSFW) with radial two degrees of freedom (DOFs) active magnetic bearing (AMB) and axial three DOFs AMB, the vibration analysis, measurement and balancing are conducted to mitigate the influences caused by unbalance terms in this article. Firstly, the force models of MSFW rotor are developed, and the vibration phenomenon caused by the residual unbalance mass of flywheel rotor is analyzed. Furthermore, the vibration testing platform for measuring the vibration of MSFW on five DOFs is introduced, and then the vibration balancing method is investigated. Finally, the vibration magnitude of MSFW rotor induced by the residual unbalance mass is analyzed by measuring dynamic displacements, and the effectiveness of vibration balancing method is verified by comparing vibration magnitudes and power spectrum densities of the MSFW system with different situations, the static unbalance term is reduced by 90.5%, and the dynamic unbalance term is reduced by 82.4%.
