Magnetic lift device for an x-ray tube

Last updated:

Abstract:

Technology is described for a magnetic lift device for an x-ray tube. In one example, an anode assembly includes an anode, a bearing assembly, a ferromagnetic shaft, and a lift electromagnet. The anode is configured to receive electrons emitted by a cathode. The bearing assembly is configured to stabilize the anode during a rotation of the anode. The ferromagnetic shaft is coupled to the anode and has an axis of rotation that is substantially collinear with an axis of rotation of the anode. The lift electromagnet is configured to apply a magnetic force to the ferromagnetic shaft in a radial direction.
