Flywheel Energy Storage System is an efficient and environmental friendly battery, and a rotor dynamics analysis is necessary as the rotor working in a high rotating speed. In this paper, a rotor dynamics analysis of a Flywheel Energy Storage System rotor was carried out by Prohl-Myklestad method, got the critical speeds and unbalance response which are useful for further work. In order to reduce the impact of rotor vibration, an optimization was given with the result that the displacement of some key points fall of 40%.
