Abstract

The present invention relates to a magnetic suspension bearing supported by magnetic force, which comprises one or more magnets fixed on a shaft directly or indirectly which can rotate with said shaft, and matching magnets provided in a certain space, wherein the magnetic polarity and magnitude of magnetic force of the matching magnets match with the magnetic polarity and magnitude of magnetic force of said one or more magnets to achieve the full suspension rotation of said shaft, and said magnets and/or matching magnets are permanent magnets. The present invention is of simple design and large power, with many other advantages such as great rigidity and great load-bearing capability and widely use in various fields.
