ABSTRACT:
X-ray tubes with a magnetic bearing either have the disadvantage that the anode must be at earth potential, so that an asymmetric high-voltage supply is required or that -- in the case of a symmetric high voltage -- a relatively wide air gap is necessary which requires a high driving force and a bearing which has a certain amount of drawbacks. The invention provides an insulator between the anode which is at the high-voltage potential and the rotor which is at the earth potential, so that the air-gap between the rotor and stator can be relatively small and an effective magnetic bearing is possible.
