High speed flywheel on magnetic bearings

摘要

A high speed energy storage flywheel comprises a rotor (1) which is located in a vacuum chamber (3) provided in a stator housing (2) and is supported by magnetic bearings (5, 6, 7) with respect to said stator housing (2). A fluid tank (10) is used for releasing in a controlled manner a fluid inside the vacuum chamber (3) and therefore create a braking effect on the rotor (1) by friction.
