| Zusammenfassung: | The invention relates to a rotary anode arrangement with a rotary anode (104), a rotor (143) for driving the rotary anode (104) and a stator (105), which exerts a torque on the rotor (143). The stator (105) comprises at least one coil (151) for generating a first magnetic field and at least one permanent magnet (152) for generating a second magnetic field. The invention also relates to an X-ray tube with the rotary anode arrangement according to the invention. The invention offers the advantage that a high electromagnetic utilization is possible with a synchronous motor that is excited by permanent magnets. |
