The permanent magnetic offset mixed radial magnetic bearing with low power consumption features that it consists of stator and rotor with air gap in between. The stator includes 8 stator magnetic poles and they forms 4 pairs in both right and left ends and separately for positive and negative directions in X and Y directions. Each stator magnetic pole consists of stator magnetic pole core and stator winding on the core, and 4 stator core yokes are connected across between two stator cores each to constitute the 8 stator magnetic poles, with magnetic isolators being set between the stator core yoke for X direction and that for Y direction. The rotor includes rotation shaft, permanent magnet, magnetizing sleeve and rotor core. The present invention has separated permanent magnetic path and electromagnetic part, lowered control current and control power consumption, small volume and light weight.
