Abstract
The invention relates to an X-ray tube with a rotating anode which is driven by a magnetic bearings motor. The anodic current is outflowed by a friction-type contact device which is located inside the shaft supporting the rotor of the motor. The friction contact device is actuated so as to cut off or establish an electrical contact between an inner wall of the rotor and the friction contact device.
