Energy distributing systems need to be equipped with adequate energy storage devices. Electric accumulators and flywheels currently belong to the most frequently used ones. For proper operation of flywheels, the minimum energy losses in the support elements are essential. Contactless high temperature superconducting bearings based on magnetic levitation offer efficient tech-nological solution. This paper deals with modeling of high-speed vertical fly-wheels mounted in superconducting bearings and investigation of their behavior. Computational simulations are focused on determination of amplitude of flywheel vibrations and magnitude of bearing forces transmitted between the rotating and stationary parts. Three operation regimes were investigated. The results of simulations show that magnitude of the magnetic moment of the permanent magnets attached to the flywheel journals (the movable part of the su-perconducting bearings) have a significant effect on their technological parame-ters. The performed study is based on computational simulations utilizing the experimentally verified theories from the field of mechanics and electromagnetics.
