摘要： The flywheel energy storage device (3) comprises a rotor (2) with at least two hubs (11, 12) and a drive (33) for the rotor (2), whereby the rotary element (23) is mounted at least via the first hub (11) with the first journal (21) in a first bearing (31) of the flywheel energy storage device (3), and at least via the second hub (12) with the second journal (22) in a second bearing (32) of the flywheel energy storage device (3), and the rotor (2) can be made to rotate by means of the drive (33) via the first and/or second journals (21, 22), whereby the journals (21, 22) in the rotor (2) are connected to each other exclusively via the hubs (11, 12) and via the rotary element (23).
