Abstract
The invention relates to a flywheel device for position stabilization of a spacecraft, comprising a carrier (1), a rotor (2), a magnetic drive (4) for the rotatingly driving the rotor (2) relative to the carrier (1), and a roller bearing (3) arranged between the rotor (2) and the carrier (1). A magnetic force can be generated between the rotor (2) and the carrier (1) by means of the magnetic drive (4) in order to pre-stress the rolling bearing (3). The outer diameter (A) of the rotor (2) can have, for example, only a maximum of 2.5 times of the rolling bearing diameter (W).
