The arcuate space formed by the outside of the magnet cover 6 and the inside of the bowl 4 has an arc angle of 0, so that the arc angles of the spaces symmetrical to both sides of the center are 0/2. Replacing the circular arc-shaped magnetic shop with the rectangular iron. Because the rectangular magnet has the advantages of the material, and it has a high material utilization rate (weight of the manufactured material / weight of the input material χ1〇〇), it can effectively reduce the production of Yongxinjiu. The cost of a magnet generator. If only the original circular arc magnet is replaced by a rectangular magnet, the volume of the above-mentioned magnet will depend on the volume of the county (10) in order to be smoothly embedded in the rounded volume, and it is impossible to provide an effective consideration. In the permanent magnet generator of the present invention, the volume reduction rate of the magnet is relatively low (about 91% of the original volume), and the volume reduction described above has little effect on the change of the magnetic field. Further, the first magnet ^ and the second magnet 13 may also include a rare earth magnet. 〃 According to the present, Di-Shi _, the tree-like Gu Weicai 2, 2 er, such as the _• 射 杂 __ 4 = heart 7, and the coil 8 is composed. Busy m1 from the center of the heart includes the center portion 3 and the bowl. The fifth figure is the return rotor according to an embodiment of the present invention. The above return rotor 1281768 4 . Two identical magnets form a magnet, and the group 14 is attached to the inner side of the bowl 4 side by side, and the adjacent two sets of magnets have the opposite polarity. The fifth rotor constituting the rotor 1 can cover the stator 2 presented in the fourth figure, and the two are in one: the rotating shaft is lightly coupled, and the rotor 1 can be rotated to make the magnet group 14 and the stator therein.
