Abstract

A force-balancing magnetic bearing with an adjustable bias magnetic field for a stator permanent magnet motor is provided. The force-balancing magnetic bearing includes four permanent magnetic poles and four electromagnetic poles, wherein a magnetic field energy of the four permanent magnetic poles is sourced from a stator permanent magnet of the stator permanent magnet motor, each permanent magnetic pole is formed by a left permanent-magnet magnetic bridge, a right permanent-magnet magnetic bridge, a magnetic adjusting section, an electromagnetic pole stator, an electromagnetic pole and permanent magnetic pole isolation plate, a permanent-magnet two-side magnetic pole connection section, a left permanent-magnet magnetic pole and a right permanent-magnet magnetic pole, a magnetic flux of each permanent magnetic pole is adjusted by the magnetic adjusting section, and the four electromagnetic poles are adjusted by currents introduced into electromagnetic pole winding coils.
