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 the 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 curved surface that contours around at least a portion of the shaft wall. A radius of curvature of the curved surface of the lift electromagnet may be greater than a radius of curvature of the lift shaft, and the spacing between the curved surface of the lift electromagnet and the shaft wall may be non-uniform.
