A ferrite three-phase permanent magnet motor is provided. The slot number Z of stator is equal to 9. Slots used for embedding winding are formed in front, at the back, on the left and right of each tooth. Each phase has three concentrated windings in series enwinding three teeth separately. The arrangement of the 9 teeth enwinding three-phase windings A, B, C is A-B-C-A-B-C-A-B-C. The permanent magnet of rotor iron core is made by hard magnetic ferrite, and the number of magnetic poles 2P is equal to 6. The motor has advantages of small winding end, small positioning torque, less copper loss and iron loss et al.
