The invention provides a permanent magnet axial magnetized radial and axial three-degree-of-freedom magnetic bearing. The permanent magnet axial magnetized radial and axial three-degree-of-freedom magnetic bearing comprises a stator and a rotor. The rotor is composed of a rotary shaft, a rotor iron core radial part and rotor iron core axial parts. The stator comprises radial control iron cores arranged on the radial outer side of the rotor iron core radial part at intervals and two axial control iron cores symmetrically arranged on the two sides of the radial control iron cores. Radial workinggaps are formed between the radial control iron cores and the rotor iron core radial part. Radial suspending windings are wound around the radial control iron cores; permanent magnets are connected between the outer edges of the two axial control iron cores and the radial control iron cores; two attraction force disks are concentrically arranged in the inner walls of the two axial control iron cores; control disks are concentrically arranged between the two attraction force disks; axial suspending windings are wound around the two attraction force disks correspondingly.
