Abstract

The embodiments relate to a rotary anode arrangement with a rotary anode, a rotor for driving the rotary anode and a stator, which exerts a torque on the rotor. The stator includes at least one coil for generating a first magnetic field and at least one permanent magnet for generating a second magnetic field. The embodiments also relate to an X-ray tube with the rotary anode arrangement. The embodiments offer the advantage that a high electromagnetic utilization is possible with a synchronous motor that is excited by permanent magnets.
