Claim 10:
11. The force-balancing magnetic bearing with the adjustable bias magnetic field for the stator permanent magnet motor according to claim 10, wherein a length d1 of a rear air gap between the left permanent-magnet magnetic pole and a thrust disc reinforcing member is equal to a length d2 of a front air gap between the left permanent-magnet magnetic pole and the thrust disc reinforcing member, a length d3 of a rear air gap between the electromagnetic pole stator and the thrust disc reinforcing member is equal to a length d4 of a front air gap between the electromagnetic pole stator and the thrust disc reinforcing member, a length w3 of a rear air gap between the electromagnetic pole stator and the thrust disc is equal to the length d1 of the rear air gap between the left permanent-magnet magnetic pole and the thrust disc reinforcing member, and a length w4 of a front air gap between the electromagnetic pole stator and the thrust disc is equal to the length d2 of the front air gap between the left permanent-magnet magnetic pole and the thrust disc reinforcing member.
