Advantageously, as shown in fig. 6, yoke portion 100 is provided with for limiting to main teeth portion 200 in the circumference in yoke portion 100
The stopper slot 110 of position, stopper slot 110 can be located on the inner peripheral surface or outer peripheral face in yoke portion 100, and main teeth portion 200 is installed on spacing
In groove 110, prevent main teeth portion 200 from sliding in yoke portion 100.
The present invention some specific embodiments in, in the first tooth boot portion 300 and the second tooth boot portion 301 each
Yoke portion 100 axially towards the surface to inner side, in other words, in the first tooth boot portion 300 and the second tooth boot portion 301 each
Towards each in the surface at the center of stator 10, i.e. the first tooth boot portion 300 and the second tooth boot portion 301 towards rotor
20 surface, can be with plane or cambered surface, it is also possible to combined by plane and cambered surface, and Fig. 2 shows that the direction of tooth boot portion 300 turns
Example of the surface of son 20 for cambered surface, it is possible thereby to adjust and the air gap between rotor 20, so as to improve poly- magnetic effect.
Alternatively, the surface towards rotor 20 of each in the first tooth boot portion 300 and the second tooth boot portion 301 can be with
Combined by nonconcentric(al) multiple arc-shaped surfaces, be beneficial to each harmonic content in adjustment air gap optimizing making an uproar for motor 1
Acoustic vibration.
In some specific embodiments of the present invention, as shown in figure 3, the first tooth boot portion 300 and the second tooth boot portion 301 can be with
Helical teeth structure is collectively configured to reduce cogging torque, specifically, each in the first tooth boot portion 300 and the second tooth boot portion 301
Individual be divided axially into multistage 320 along yoke portion 100, the side of 301 multistage 320 of the first tooth boot portion 300 and the second tooth boot portion is in yoke portion
Stagger in 100 circumference successively setting.
For example, the axial direction in the side edge yoke portion 100 of the multistage 320 of the first tooth boot portion 300 and the second tooth boot portion 301
Shorten successively, and the axial direction in the opposite side edge yoke portion 100 of the multistage 320 of the first tooth boot portion 300 and the second tooth boot portion 301 is successively
Lengthen, circumferential all first tooth boot portions 300 in yoke portion 100 are consistent with the arrangement regulation of the multistage 320 in the second tooth boot portion 301,
I.e. all first tooth boot portions 300 and the second tooth boot portion 301 are inclined to same direction in the circumference in yoke portion 100, so as to constitute into
Helical teeth structure.
Again for example, by by positive and negative for the multistage 320 of the first tooth boot portion 300 in elongated portion 210, by the second tooth boot portion
301 multistage 320 is positive and negative in elongated portion 210, i.e., per section 320 of shape is identical, by choosing in multistage 320
Or several, after being flipped up in the week in yoke portion 100 in elongated portion 210, so as to constitute helical teeth structure on the whole.
