Design and control of a novel flywheel energy storage system assisted by hybrid mechanical-magnetic bearings …
Active magnetic bearings and passive magnetic bearings are the alternative bearings for flywheel energy storage systems [27], [28]. Active magnetic bearing has advantages such as simple construction and capability of supporting large loads, but the complexity of the control system is daunting.
Revterra
Revterra stores energy in the motion of a flywheel. Electric energy is converted into kinetic energy by a spinning rotor. When needed, that kinetic energy is converted back to electricity. Revterra''s innovative approach leverages passively stable magnetic bearings and low-cost steel alloys to improve efficiency and reduce cost.
