Abstract
In one example, a lift assembly may exert a force on a rotatable anode of an X-ray source. The lift assembly may include a lift shaft and a lift electromagnet. The lift shaft may be coupled to an anode and configured to rotate around an axis of rotation of the anode. The lift electromagnet may be configured to apply a magnetic force to the lift shaft in a radial direction. The lift electromagnet may include a coupling portion extending between an interior of a vacuum envelope and an exterior of the vacuum envelope and a winding portion coupled to the coupling portion. Windings may at least partially surround the winding portion.
