Abstract

In a magnetically borne position-stabilizable flywheel, the force generation systems (at least for the radial drive) are designed in accordance with the electrodynamic principle and disposed in the interior of the wheel hub. The coils are situated on the stator and the associated permanent magnets on the rotor. Undesired oscillations are effectively damped. As a result of the displacement of the drive into the wheel hub, it is possible to use small coils. The swivel range of the wheel is sufficiently large.
