The production efficiency of high double-rotor machine.
For the number of stator external tooth 12 and stator internal tooth 212, the utility model is simultaneously not construed as limiting, for example, stator
The quantity of external tooth 12 and stator internal tooth 212 can it is equal can not also be equal, stator internal tooth 212 and 12 corresponding pole of stator external tooth
Number, phase can also be inconsistent, and shape, the size of stator external tooth 12 also can be inconsistent with stator internal tooth 212.
In some embodiments of the utility model, iron core 2 is detachably arranged on stator outer iron core 1 in stator.Change speech
It, iron core 2 and stator outer iron core 1 are respectively formed as single component in stator, and iron core 2 is installed on stator outer iron core 1 in stator
And can be disassembled from stator outer iron core 1, so as to facilitate the installation of iron core 2 and stator outer iron core 1 in stator to assemble, also favorably
In the replacement and maintenance of iron core in stator 2 and stator outer iron core 1.
Alternatively, cam portion 213 can be equipped with stator at least one in iron core 2 and stator outer iron core 1, iron in stator
Another in core 2 and stator outer iron core 1 is equipped with the recessed buckle 214 coordinated with cam portion 213.Thus, recessed buckle 214 is passed through
With the cooperation in cam portion 213, it can not only realize being detachably connected for iron core 2 in stator outer iron core 1 and stator, be also convenient for stator
The installation of interior iron core 2 and stator outer iron core 1, and it is simple in structure.
As Figure 1-Figure 4, cam portion 213 and recessed buckle 214 are formed in stator between iron core 2 and stator outer iron core 1,
One i.e. in the recessed buckle 214 in cam portion 213 is formed in stator in the outer circumferential surface of iron core 2 and cam portion 213 and recessed buckle 214
Another be formed in the inner peripheral surface of stator outer iron core 1, recessed buckle 214 and cam portion 213 coordinate be iron core 2 in stator periphery
The inner peripheral surface of face and stator outer iron core 1 coordinates.
In some specific examples of the utility model, with reference to shown in Fig. 1-Fig. 4, cam portion 213 may be formed in stator
On the outer circumferential surface of iron core 2, recessed buckle 214 may be provided on the inner peripheral surface of stator outer iron core 1, other in the utility model show
Example, recessed buckle 214 may be formed in stator on the outer circumferential surface of iron core 2, and cam portion 213 may be provided in the inner peripheral surface of stator outer iron core 1
On.
Alternatively, cam portion 213 and recessed buckle 214 can be respectively multiple and be opened along the circumferentially-spaced of stator core 100
Set, so as to strengthen the structural strength in stator between iron core 2 and stator outer iron core 1.Further, as Figure 1-Figure 4,
The shape in cam portion 213 is adapted with the shape of recessed buckle 214, and cam portion 213 may be mounted in recessed buckle 214, recessed buckle
214 opening is relatively narrow, so as to prevent cam portion 213 from departing from from recessed buckle 214.As shown in figs 2-4, from the inside to the outside
On direction, the width in cam portion 213 is gradually reduced, and the shape of recessed buckle 214 is adapted with cam portion 213, is thus prevented convex
Buckle 213 departs from from recessed buckle 214, for example, as shown in Fig. 2, cam portion 213 can be formed as boss-shaped.As shown in Figure 1
In example, cam portion 213 can be formed as roughly elliptical shape, and the shape of recessed buckle 214 is adapted with cam portion 213, recessed button
Portion 214 is minimum in the width of the opening of the radial direction of stator core 100, so that not only bad for cam portion 213 and recessed buckle
214 cooperation, departs from prevented also from cam portion 213 from the opening of recessed buckle 214.
In some embodiments of the utility model, iron core 2 can include iron core 21, Duo Gefen in multiple segmentations in stator
The circumferential direction of iron core 2 along stator of iron core 21 joins end to end in section.In other words, iron core 2 is formed as segmented, multiple segmentations in stator

Shown in Fig. 5, stator internal tooth 212 is located at the inner side of yoke 211 in sectionalized stator, circumferential two of yoke 211 in each sectionalized stator
End is fitted close with yoke 211 in the sectionalized stator of iron core 2 in two neighboring sectionalized stator respectively, yoke 211 in multiple sectionalized stators
Yoke in the stator of iron core 2 in cooperation composition stator.Further, iron core 21 can be equipped with a stator internal tooth 212 in each segmentation,
The number of iron core 21 is identical with stator internal tooth 212 in segmentation.Thus, winding displacement wiring and not can be carried out to each stator internal tooth 212
The less problem in gap is influenced between by the stator internal tooth 212 of the prior art, thus be more advantageous to stator internal tooth 212 around
Line, further to improve the production efficiency of motor.
In some examples of the utility model, as shown in fig. 4-5, cam portion 213 can be equipped with stator on iron core 2,
Stator outer iron core 1 is equipped with recessed buckle 214, and yoke 211 is equipped with semi-convex buckle 215 in each sectionalized stator, in adjacent sectional stator
The semi-convex buckle 215 of yoke 211 splices to coordinate with recessed buckle 214.Thus, in stator iron core 2 and stator outer iron core 1 by passing through
Cam portion 213 and recessed buckle 214 coordinate and are connected, as shown in figure 5, in each sectionalized stator at least one section of yoke 211 equipped with semi-convex
Buckle 215, the semi-convex buckle 215 of yoke 211 can be spliced to form convex suitable for coordinating with recessed buckle 214 in adjacent sectionalized stator
Buckle 213, so that the mating connection of iron core 2 and stator outer iron core 1 in stator can not only be realized, and can realize each point
The cooperation of iron core 21 and stator outer iron core 1 in section, in multiple segmentations the connection of iron core 21 be in stator outer iron core 1 and be connected,
So as to can also strengthen the closely coupled of iron core 21 in multiple segmentations, also can further strengthen in multiple segmentations iron core 21 with it is fixed
Sub- outer iron core 1 coordinates.
Alternatively, the circumferential both ends in yoke portion are respectively equipped with semi-convex buckle 215 in each stator, as shown in Figure 4 and Figure 5,
The sliceable formation cam portion 213 of the semi-convex buckle 215 of the connecting place of iron core 21 is with recessed buckle 214 to coordinate in multiple segmentations,
So as to strengthen the tight fit of iron core 21 in the structural strength of iron core 2 and multiple segmentations in stator, further strengthen each
The cooperation of iron core 21 and stator outer iron core 1 in segmentation.
