Claim 8:
9. A method for controlling a stable suspension of a rotor of the force-balancing magnetic bearing with the adjustable bias magnetic field for the stator permanent magnet motor according to claim 8, wherein with respect to the permanent magnet sections extending out of the core and generating a bias force, a size of portions, embedded in the left permanent-magnet magnetic pole and the right permanent-magnet magnetic pole, of the magnetic adjusting sections is adjusted so as to adjust the bias force, and currents in opposite directions are applied to portions, on two sides of the permanent-magnet two-side magnetic pole connection sections in bias magnetic circuits of the permanent magnet sections, of the electromagnetic pole stator so as to adjust an electromagnetic force.
