Abstract
The present invention relates to a thrust magnetic bearing for bias compensation, and more particularly, to a thrust magnetic bearing for bias compensation in which annular permanent magnets and electromagnets are disposed to face each other with respect to a levitated member and the permanent magnets are formed to be asymmetrical in lengths thereof in an axial direction to thus exert an attractive force for compensating for a bias by the difference in the lengths of the permanent magnets in the axial direction to compensate for the bias, and a current supply for bias magnetic flux is not required, saving energy.
