Bearings for flywheel energy storage systems (FESS) are absolutely critical, as they determine not only key performance specifications such as self-discharge and service live, but may cause even safety-critical situations in the event of failure. By analyzing aspects of the FESS supersystem, requirements and load collectives for the bearing system are defined. The reader is introduced to the topic of gyroscopic motion, which is of high relevance for the determination of vehicular FESS bearing loads. The importance of flywheel balancing to reduce radial bearing loads is also presented in an easy to understand way. Rotor dynamics and resonance phenomena are considered, and practical examples of bearing seat designs, which can mitigate effects such as residual unbalance, are given.
