ABSTRACT:
The present invention relates to a kinetic wheel arrangement comprising a stator, a rotor and a magnetic suspension, wherein said rotor comprises a central recess about said axis of rotation; there is disposed in said central recess of the rotor a pressure system provided with a screw which is connected to the stator and of which the axis merges with said axis of rotation of the rotor, this pressure system being adapted to take a first position for which said rotor is free to rotate about its axis of rotation while being suspended by its magnetic suspension, and a second position for which it presses said rotor against said stator to immobilize it; and remotely-controlled means are provided to cut said screw between said stator and said rotor. The invention is particularly applicable to the caging of the rotor in phases during which the kinetic wheel arrangement undergoes considerable mechanical stresses.
