Abstract
A hybrid type permanent magnet bearing system which utilizes four permanent magnet rings to replace the mechanical bearings. These rings are divided into two separated groups along an axis, where each group has an inner ring and a separated outer ring. At least one permanent magnet ring has a surface facing the gap between the two groups but being not vertical to the axis. Hence, inside the gap, the magnetic field between these permanent magnet rings is not non-uniform over different directions, and then it may behave as the axial and radical bearing simultaneously.
