Embodiment 1

[0041] Such as figure 1 and figure 2 As shown, the bipolar transverse flux permanent magnet synchronous motor in Embodiment 1 of the present invention is a three-phase 10-pole stator permanent magnet type bipolar magnetic concentration type transverse flux permanent magnet synchronous motor, which includes a rotor part 1 and Stator part 2.

[0042] It includes a rotor support body 3, a rotor core 4 and a rotor shaft 5, the rotor core 4 is embedded in the outer surface of the rotor support body 3, and the rotor support body 3 is fixed on the rotor shaft 5;

[0043] The rotor cores 4 belong to three phases A, B, and C. The rotor cores 4 of each phase are evenly distributed along the circumference in the shape of isosceles triangular waves. The rotor cores 4 of each phase form a total of 10 isosceles triangles. The adjacent Two iron cores constitute the two sides of the triangular wave, such as figure 2 The rotor core 4-1 and the rotor core 4-2 are shown. Such as figure 2 A...

Embodiment 2

[0053] Such as Figure 15 , 16 As shown in and 17, the difference between the first embodiment and the second embodiment of the present invention is mainly reflected in that the three-phase stator units are staggered in the same direction along the axial direction by 12°, that is, the stator core 6 and the permanent magnet 7 of each phase are also staggered in the same direction in turn The angle is 12°, and the rotor units of each phase do not differ in angle, and they are all aligned. Such as Figure 16 As shown, the B-phase stator is staggered by 12° from the A-phase stator as a whole, and the C-phase stator is 12° from the B-phase stator as a whole, that is, 24° from the A-phase stator as a whole.

[0054] The same as the first embodiment, the 10 "C" shaped stator cores 6 and 10 permanent magnets 7 in each phase are still distributed in a staggered manner along the circumferential direction and arranged evenly, and all the permanent magnets 7 are magnetized tangentially ...
