ABSTRACT:
The invention relates to an X-ray tube. The tube has a rotary anode which is rotatably journalled by means of a magnetic bearing having a stator comprising a magnet yoke which intersects the outer walls of the tube and which is magnetizable by magnets arranged outside the tube. The magnet yoke comprises radially extending pole faces which enclose gaps in conjunction with radially extending pole faces of a rotor connected to the rotary anode. The rotor consists of a soft-magnetic disk, which provides the magnet yoke which closes the magnet yoke of the stator.
