Abstract

A flywheel comprises a rotor (7) with a annular flywheel mass (1), a magnetic bearing device with controllable coils for mounting the rotor (7) free of contact, the magnetic bearing having two radial pole plates (14, 15) on the stator pole with a permanent magnet (24) between them and two electrical coils, a rotor ring (6) being connected to the flywheel mass (1) to provide annular air gaps between the pole surfaces (10, 11) of the rotor ring 6 and the pole surfaces (22, 23) of the pole plates (14, 15) and a mechanical auxiliary bearing, Figure 3, having an annular limb 59 which extends between extensions 56, 57 of the pole shoes 20, 21. If tilting or axial misalignment of the rotor occurs, the auxiliary bearing acts to limit such misalignment and reset the flywheel. The auxiliary bearing acts as an emergency bearing in the event of failure by the magnetic bearing. The auxiliary bearing may alternatively be a rolling contact bearing having one race fixed to the stator and the other race engageable with the rotor if misalignment occurs. <IMAGE>
