ABSTRACT:
The invention provides a satellite momentum wheel with passive magnetic centering means, between a stator and a rotor comprising at least one passive radial magnetic centering device, at least one axial magnetic centering device slaved to an axial velocity sensor and to an axial position sensor, at least one centering motor-generator unit having a magnetized rotor and a stator with toroidal windings switched by an angular rotation position sensor, at least one damping device, two emergency taper pivots for safe centering of the axial mounting of the rotor one of which is possibly in contact with a doped-polyamide step bearing on the stator, and interconnecting means between the wheel rim and the axis of said pivots employing a so-called coated arrayed-thread type cycloprofile structure.
