It should be noted that, structure, the feature and advantage etc. of motor core body assembly of the present invention, motor core body and motor will be illustrated by way of example below, but all descriptions are only used to be described, and should be understood as any restriction is formed to the present invention.In addition, described or implicit any single technical characteristic in each embodiment mentioned by herein, or be shown or implicit any single technical characteristic in the drawings and in which, still can between these technical characteristics (or its equivalent), proceed combination in any or delete, thus obtain other embodiments of the present invention more that may directly do not mention in this article.
Incorporated by reference to reference to figure 1 and Fig. 2, illustrate schematically an embodiment of motor core body assembly of the present invention in the drawings, the pole body of motor core body assembly and pole shoe are in released state in FIG, the pole body of motor core body assembly and pole shoe are then in engagement state in fig. 2, below be just specifically described by this example.
In this embodiment provided, this motor core body assembly 1 comprises body 2 and multiple pole shoe, and body 2 has 10 pole bodies 3 be integrally formed therewith, these pole bodies 3 carry out being evenly arranged and stretching out along the circumference of body 2, so that be used for winding excitation winding (not shown) thus formed yoke, when producing magnetic flux after excitation winding making current.As shown in Figure 1, the pole shoe 5 be separated with pole body 3 is also provided with in motor core body assembly 1, such pole shoe 5 is by arrange respectively thereon and this pole shoe 5 and pole body 3 are assembled together by the pole body 3 and junction surface 6 of Corresponding matching and junction surface 4 (such as, can adopt concaveconvex structure, helical structure, ferrule structure etc.).That is, by adopting removably in motor core body assembly of the present invention, can be very convenient, flexibly and quickly disassembling operations is carried out to pole body 3 and pole shoe 5, thus as illustrated in fig. 2, after by each junction surface 6 of these pole shoes 5, correspondence is installed to each junction surface 4 of these pole bodies 3 respectively, these pole shoes 5 can be respectively fixed on these pole bodies 3, thus just can provide desired magnetic flux at motor internal in use by the motor core body assembly 1 after assembling.
For pole shoe 5, when adjusting for its overall dimension and structure structure, will have influence on the excitation winding be set around on pole body 3 form the magnetic flux size of yoke and the distribution of the magnetic line of force, although therefore allowing pole shoe 5 to be only designed and manufactured into completely has a kind of overall dimension, but in preferred cases, a series of pole shoe group with different overall dimension can be configured, such as in these pole shoe groups, the each pole shoe be under the jurisdiction of in each pole shoe group has identical thickness specification, between each pole shoe being under the jurisdiction of different pole shoe group, then there is thickness specification variant each other.
Be understandable that, above-mentioned term " thickness specification " refers to the thickness of each pole shoe at the identical of them or similar position.For example, such as in FIG, the thickness h just can choosing the outer surface place being positioned at pole shoe 5 is easily used as the thickness specification of pole shoe group, thus as the multiple different pole shoe groups that standard provides thickness h there are differences.As an example, can select that the thickness h of above-mentioned pole shoe 5 is corresponding with the magnetic flux size of motor internal to be associated, namely corresponding can be reflected the size variation of magnetic flux by the different-thickness value of apolegamy pole shoe 5.
Also it is to be noted, due in motor core body assembly of the present invention, pole shoe 5 can be selected and removably be assembled to adjustment pole body 3 realizing magnetic flux, and therefore these pole shoes 5 can have any possible suitable size and outer shape etc.Such as, under optional situation, the appearance profile of pole shoe 5 can be configured to a leg-of-mutton part or a fan-shaped part, or be configured to other suitable shape.Certainly, in motor core body assembly of the present invention, by arranging the multiple concrete configuration of pole shoe 5 and size to realize optimizing distribution of the magnetic line of force flexibly under different application scenarios, at all this adopt those motor chip or the motor core bodies etc. such as adopting the modes such as integrated punch forming to make in prior art cannot realize.Further, employing the present invention also need not as in the state of the art, when the magnetic flux demand in the face of motor internal changes, just need to redesign, manufacture the motor chip or motor core body that make new advances, or by increasing, reduce the new demand that stacked motor chip number meets magnetic flux, and be can be very convenient in the present invention, by various, there is different profile neatly, the pole shoe fast assembling-disassembling of size need not winding excitation winding again to the pole body of motor core body assembly, therefore can greatly simplify the operation course, adjustment process for magnetic flux is not only efficient, easy, and can effectively reduce costs.
In addition, due in motor core body assembly of the present invention, pole body 3 and pole shoe 5 are separated each other under unassembled state, therefore the two can be selected respectively different materials and process for machining and manufacturing to make.As optional situation, the magnetic metal material such as such as silicon steel can be adopted to make pole body 3, and adopt such as copper, aluminium etc. in material, to be softer than the metal material of pole body 3 material therefor to make pole shoe 5, while required magnetic flux is provided, so just likely reduces integral material cost and the manufacturing cost of motor core body assembly.In addition, when the metal material that pole shoe 5 adopts such as copper, aluminium etc. more soft relative to silicon steel etc., just can make full use of its material behavior according to conditions of demand of magnetic flux etc. by pole shoe 5 more easily optimal design, manufacture required profile geometric profile, and also contribute to thus selecting the lower suitable material of some costs to reduce the overall manufacturing cost of motor core body assembly, therefore be very beneficial for designing and realize optimizing distribution of the magnetic line of force, improve the design level of motor, product quality and the market competitiveness further.
Should be appreciated that and allow in the present invention to need design neatly and above-mentioned motor core body assembly is provided according to practical application, just this is further described below.
For example, although must not arrange, can consider to arrange one or more breach 7 alternatively on the outer surface of cupular part of pole shoe 5, to reduce motor cogging torque in use.In addition, the concrete magnitude setting and position etc. of above-mentioned breach 7 can set according to practical application.
Again for example, although in the example given, the junction surface 4 of the pole body 3 of motor core body assembly 1 is all shown as being provided with groove, and the junction surface 6 of pole shoe 5 is all shown as being provided with the projection suitable with above-mentioned groove, but also above-mentioned junction surface 4 and junction surface 6 can be respectively arranged with projection suitable each other and groove.In addition, some that also can make in these junction surfaces 4 and junction surface 6 are respectively arranged with projection and groove, and other in these junction surfaces 4 and junction surface 6 are respectively arranged with groove and projection, as long as they can mutually adaptively engage each other, thus pole shoe 5 fixedly can be assembled on pole body 3.
Be re-used as citing, preferably the pole body 3 of motor core body assembly 1 and pole shoe 5 are arranged to be evenly arranged along the circumference of the body 2 of motor core body assembly 1 in the present invention, certainly also allow not to be that circumference along body 2 is evenly arranged in some cases by these pole bodies and pole shoe.
In addition, the concrete size of motor core body assembly of the present invention and each part thereof (such as, body 2 along motor shaft to thickness, the length of pole body 3, the thickness etc. of pole shoe 5) and they corresponding processing technology (such as, punching press, casting etc.) all can according to practical application need carry out selections setting.Also it is to be noted, also allow in the present invention to adopt the body 2 in lamination process stacked formation motor core body assembly and/or pole shoe 5, namely the modes such as punching press can be such as adopted to produce some one single chips for the formation of body 2 (or pole shoe 5), and then use such as rivet, the connected mode such as welding is fixed together stacked for these one single chips, thus obtains the body 2 (or pole shoe 5) in motor core body assembly of the present invention.
Based on motor core body assembly provided by the present invention, the motor core body for motor can be made, can by excitation winding winding on the pole body of motor core body assembly of the present invention.Thus, in the R & D design or the process such as use, maintenance of motor, when needing adjustment or changing the magnetic flux of motor internal, by original pole shoe is replaced with suitable pole shoe, just can be very convenient, fast and realized efficiently.
Because motor core body of the present invention is applicable on existing various types of motor (as direct current machine, alternating current machine etc.), and it has foregoing many merits, therefore be applicable to very much such motor core body to be attached in various motor to be such as used as motor stator, thus these technical advantages of the present invention can be given full play of.
Below only come by way of example to illustrate motor core body assembly of the present invention, motor core body and motor in detail, this a few example is only for principle of the present invention and embodiment are described, but not limitation of the present invention, without departing from the spirit and scope of the present invention, those skilled in the art can also make various distortion and improvement.Such as, although be provided with 10 pole bodies and 10 pole shoes in the motor core body examples of components provided altogether, the present invention allows to need to set the concrete number of these pole bodies and pole shoe and their positions on motor core body assembly according to application completely.And for example, although in the motor core body examples of components provided, pole body is shown as extending toward the outside along the body circumference of motor core body assembly, but in fact these pole bodies also can be circumferential towards extending internally along the body of motor core body assembly.For another example, under at some, such as technical staff carries out the application scenarios such as R & D design, performance test, some pole bodies of motor core body assembly need not fit on pole shoe also be possible.In addition, the pole body in motor core body assembly, pole shoe also can adopt identical material and/or identical processing technology to make.Therefore, all equivalent technical schemes all should belong to category of the present invention also by every claim of the present invention is limited.
