The present invention is achieved in that a kind of composite permanent magnetism flux switching motor stator structure of the present invention; Comprise the stator core that is provided with line embedding groove; Its stator core is combined into cylindrical shape by the stator core of the U-shaped structure more than at least 4; In the stator core of each U-shaped structure, all be provided with the line embedding groove of a U font; Between the stator core of per two the U-shaped structures that are combined into cylindrical shape, all be separated with first permanent magnet blocks of a square structure; On two axial ends of each stator core, all post second permanent magnet blocks that is provided with U-lag respectively, the end surface shape of second permanent magnet blocks and the end surface shape of stator core match, and be all identical with the pole polarity of two second permanent magnet blocks on its contact-making surface with two first permanent magnet blocks of same stator core contact; Post the magnetic conduction end plate of teeth groove structure in the outside of second permanent magnet, the line embedding groove shape of the slot form on the magnetic conduction end plate and the U font of the stator core of U-shaped structure is identical and align.
Stator core is that the solid material of magnetic conduction constitutes or the flaky material lamination of magnetic conduction constitutes.
The end at the above-mentioned first permanent magnet blocks two ends withstands on respectively on the medial surface of magnetic conduction end plate at its two ends, and the end at the second permanent magnet blocks two ends withstands on respectively on the side of first permanent magnet blocks at its two ends.
The end of perhaps adjacent two second permanent magnet blocks leans together each other, and the end at the first permanent magnet blocks two ends withstands on respectively on the medial surface of second permanent magnet blocks at its two ends.
Leave the gap between the end of two second perhaps adjacent permanent magnet blocks, and the end at the first permanent magnet blocks two ends is respectively over against the position, gap between two the second adjacent permanent magnet blocks ends at its two ends.
Owing to adopted technique scheme; The present invention is combined into cylindrical shape with the stator core that the stator core of traditional cylindrical shape is made into by a plurality of U-shaped structures; And in the stator core of each U-shaped structure, all produce the line embedding groove of a U font; Simultaneously on four faces of the stator core of each U-shaped structure, all adopt permanent magnet blocks that it is surrounded, and at the two ends of stator the magnetic conduction end plate is set all stator cores and permanent magnet blocks are grasped.The present invention has strengthened the permanent magnetic field of original stator greatly through this structure, thereby obtains higher power density output, and can effectively avoid existing axial leakage field problem in the prior art.Therefore; The present invention compared with prior art; The present invention not only has the advantage that the axial end portion leakage field is low, the magnetic efficiency utilance of permanent magnet high, power density output is big, but also has anti-electromagnetic interference and advantages such as Electromagnetic Compatibility is strong, compact conformation, stable work in work.
