Abstract

A superconducting magnetic bearing assembly has an outer element having an axis. Disposed about the axis, the outer element has first and second inverted generally conical surfaces, each surface disposed at an acute angle to the axis. These surfaces define a volume. Fixedly disposed within the volume is an inner element rotatable relative to the outer element. The inner element has first and second conical inner elements. The first conical inner element has a first surface opposed to and spaced from said first generally conical surface of the outer element, the opposed first surfaces lying generally parallel to each other. The second conical inner element has a second surface opposed to and spaced from the second generally conical surface of the outer element, the opposed second surfaces lying generally parallel to each other. A spacer is disposed between first and second conical inner elements for adjusting the axial spacing between the surfaces of the conical inner elements, thereby to adjust the dimension of the space between the opposed surfaces. A first element is of superconductive material and a second element is of a material that can generate a magnetic field about the sec…
