Abstract
A rotor shaft () for a magnetic bearing device () is disclosed. The shaft comprises an inner portion on whose periphery a plurality of targets () separated by spacers () are mounted. This is achieved exerting an axial pressing force (F, F') to the peripheral parts, rather than applying a radial press fit. In this manner, a simplified construction, a higher stiffness and a higher stability at high rotational speed are achieved. Further disclosed is a rotor having a thrust disk () whose diameter decreases towards the periphery. This allows to use a larger thrust disk at a given rotational speed.
