Abstract
The stator of the drive motor of a rotary anode X-ray tube is composed of a plurality of radially displaceable sector elements. As a result, the anode can be accelerated and decelerated while using a narrow airgap, and the airgap can be widened for bridging the high voltage to be applied at a later stage. The invention can be realized in automated form by using a blocking device for the high voltage and a tachometer.
Claims4
An X-ray tube comprising a rotary anode and a drive motor which comprises a rotor which is rigidly connected to the anode and a stator which is arranged about the rotor, characterized in that the stator is composed of a plurality of radially movable sector elements.
