In order to make the purpose of this utility model, technical scheme and advantage clearer, below in conjunction with accompanying drawing And embodiment, this utility model is further elaborated.Should be appreciated that described herein specifically Embodiment, only in order to explain this utility model, is not used to limit this utility model.

Below in conjunction with specific embodiment, realization of the present utility model is described in detail.

The corresponding same or analogous parts of same or analogous label in the accompanying drawing of the present embodiment；New in this practicality In the description of type, it is to be understood that if having term " on ", D score, "left", "right" etc. refer to The orientation shown or position relationship, for based on orientation shown in the drawings or position relationship, are for only for ease of description originally Utility model and simplification describe rather than indicate or imply that the device of indication or element must have specific side Position, with specific azimuth configuration and operation, therefore the being merely cited for property of term of position relationship described in accompanying drawing Explanation, it is impossible to be interpreted as the restriction to this patent, for the ordinary skill in the art, Ke Yigen The concrete meaning of above-mentioned term is understood according to concrete condition.

With reference to Fig. 1～5, it it is the embodiment of this utility model offer.

Embodiment one

The stator structure that the present embodiment provides, can be used in the structure of motor, for making with rotor engagement With, it is achieved electric energy and mechanical energy and mechanical energy and the mutual conversion of electric energy.

With reference to shown in Fig. 1, for the preferred embodiment of this utility model offer.

Stator structure includes stator body 10, is formed with through stator body 10 upper end in this stator body 10 Face and the first through hole 11 of lower surface；Stator body 10 has several the most adjacently positioned subregions 101, These several subregions 101 are ring-type around being formed, and its each subregion is provided with cannelure, and cannelure is longitudinal cloth Put, and be looped around the periphery of whole subregion；Embedding in the cannelure of each subregion it is wound with copper cash, say, that Copper cash is wound around along cannelure, forms ring-wound shape, and copper cash is completely embedded in cannelure, Bu Huixian It is exposed at outside the surface of subregion 101.

In above-mentioned stator structure, in the first through hole 11, it is placed with rotor, by stator body 10 On each subregion 101 embedding around copper cash, form winding, so, the rotor being placed in the first through hole 11 is with fixed Sub-body 10 coordinates, it is achieved mutually converting between electric energy and mechanical energy in motor.

The stator structure that above-described embodiment provides, by arranging cannelure on the subregion 101 of stator body 10, Being wound on embedding for copper cash in cannelure, copper cash is completely embedded in subregion 101, will not convex be exposed at outside subregion 101, In i.e. copper cash is completely embedded in stator body 10, the most convex it is exposed at outside stator body 10, is using stator structure During, do not have a phenomenon of leakage field, improve the quality of stator structure, simple in construction, practical.

Specifically, subregion 101 includes intrados 1011 and extrados, and several intrados 1011 enclose shape Become the first through hole 11.

For the ease of the rotation of rotor, stator body 10 and the first through hole 11 are cylindrical.

In the present embodiment, multiple subregions 101 are one-body molded, and namely stator body 10 is formed in one manufacture, So, subregion 101 is then as a region of stator body 10, and it is whole fixed that multiple subregions 101 enclose formation Sub-body 10.

Subregion 101 is formed two the second through holes 103 being longitudinally arranged, these two the second through hole 103 phases Interval is arranged, and distinguishes upper surface and the lower surface of through subregion 101；The upper surface of subregion 101 and lower end Face, respectively towards sunken inside, forms slot stick 102, and the two ends of slot stick 102 are respectively communicated with two the second through holes 103, so, enclose between two slot sticks 102 and two through holes 103 and form above-mentioned cannelure.

In actual coiling, utilize coil winding machine, one end of copper cash is passed second through hole of subregion 101 In 103, then a slot stick 102 through subregion 101, from another second through hole 103 of subregion 101 In pass, then another slot stick 102 through subregion 101, thus complete a circulation of cannelure around Line, repeats with this, repeats coiling, and make copper cash be entirely embedded within slot stick 102 in cannelure In cannelure.

Coil winding machine coiling in cannelure can be directly utilized, it is not necessary to manually carry out coiling for the ease of producer, recessed The bottom surface of groove bar 102 is plane, so can improve the quality of stator.

Embodiment two

With reference to Fig. 2～4, another preferred embodiment provided for this utility model.

The present embodiment is with the difference of embodiment one:

Several subregions 101 are the most one-body molded, can disposably complete to make subregion 101, manufacturing process Simply, low cost.

Specifically, adjacent subregion 101 side is connected together, and forms stator body 10.In the fabrication process, Each subregion 101 the most separately fabricated, and in the cannelure of each subregion, carry out coiling respectively, then, Again the subregion 101 after several coilings is connected, form stator body 10, make simple.

For the ease of the connection between subregion 101, two sides of subregion 101 arrange several projection 104 and several mounting grooves 105, several projections 104 and mounting groove 105 are respectively along stator body 10 Longitudinal direction arrange separately, adjacent subregion 101 is connected together with mounting groove 105 by projection 104, when When subregion 101 assembles, projection 104 on a certain subregion 101 and mounting groove 105 respectively with its side The mounting groove 105 of subregion 101 and projection 104 be connected with each other, simple in construction, easy to operate.

Certainly, according to practical situation, the connected mode between subregion 101 may be arranged as multiple other Connected mode.

In the present embodiment, cannelure is arranged between attachment structure and intrados 1011 so that whole stator The structure of body 10 is compacter.

Embodiment three

With reference to Fig. 5, another preferred embodiment provided for this utility model.

The present embodiment is with embodiment two difference:

Subregion 101 includes that intrados 1011 and extrados, projection 104 engage with mounting groove 105, forms card Closing structure, cannelure is arranged between attachment structure and extrados so that the structure of whole stator body 10 is more Add compact.

The foregoing is only preferred embodiment of the present utility model, not in order to limit this utility model, All any amendment, equivalent and improvement etc. made within spirit of the present utility model and principle, all should Within being included in protection domain of the present utility model.
