摘要： This invention provides a geometrical structure configuration of maglev forces in a maglev rotational bearing apparatus. The bearing apparatus uses the magnetic forces as the suspension support for the rotational shaft, and utilizes a radial maglev support module to provide two maglev constraint forces perpendicular to and crossing on the axis of rotating shaft and an axial maglev support module to provide three maglev constraint forces parallel to the axis but non-coplanar. From the viewpoint of kinematical geometry, this machine has five linearly independent constraint forces so that the main axis is allowed to be suspended without contact and friction with static elements, and the suspension force in axial direction is better than currently available maglev bearings. The rotational shaft can be driven by a motor to perform high-speed rotational motion with noises free and vibrations free. This technique can be applied to high-speed rotational machines such as turbo molecular vacuum pumps, the spindle of high-speed machine tools, inertial gyroscopes, etc.
