Abstract
The utility model provides a stator core for magnetor, include: correspond superimposed stator towards piece group and baffle towards piece, both ends are organized at the stator towards the piece towards the piece setting to the baffle, and its shape and adjacent stator correspond towards the piece, the stator forms a T type wire winding tooth coincide body towards piece group and baffle towards the piece at least, insulating skeleton cladding on the T type wire winding tooth coincide body that the stator constitutes towards the piece with the baffle towards piece group to form the wrapping post, the cross -section of wrapping post is falling the rectangle at oblique angle. The utility model discloses a stator core for magnetor's wrapping post cross -section is for falling the rectangle at oblique angle, and is shorter for the wire winding length of the rectangular copper wire at radius angle, and the consumption of copper still less especially reduces the consumption of copper widely when batch production, in addition, for the rectangle at radius angle, simple process is makeed to the rectangle at oblique angle, and the cost is lower.
Description
Technical field
The utility model relates to magneto technical field, refers to a kind of magneto stator iron core especially.
Background technology
Magneto is formed primarily of stators and rotators, wherein stator includes stator core and coil, usually superimposed by several stator punchings and be riveted together and form stator core, structure due to stator punching is middle part is installation portion, outer rim is equally distributed T-shaped coiling tooth, the iron core outer rim of superimposed formation forms the coiling tooth of T-shaped, and then at the outer surface injection moulding insulating material of iron core, finally on the coiling tooth of stator core outer rim, winding around forms Magnetor stator.Owing to forming the stator punching of stator core, it is measure-alike, therefore the wrapping post cross section on traditional coiling tooth mostly is rectangle, in order to reach required area coil, make the thickness of iron core thicker, Heavy Weight, copper wire winding girth on rectangle wrapping post is longer, bending is comparatively large, the problem that therefore copper cash consumption is many, damage is large, cost is high.In order to solve the problem, existing a kind of improved procedure is: wrapping post cross section is round rectangle, specifically as illustrated in fig. 1 and 2.For ends of the earth motor, namely stator core has eight wrapping posts 5, and as shown in Figure 2, insulation framework 1 wraps up the first stator punching 21, second stator punching 22 and baffle plate punching sheet 3 to cross section (cross section along the C-C) shape of each wrapping post 5.But still there is the many and rounding manufacture craft relative complex of copper cash consumption in the wrapping post that cross section is round rectangle, the problem that cost is high.
Utility model content
The utility model proposes a kind of magneto stator iron core, solve that copper cash consumption in prior art is many, complex process and the high problem of cost.
Magneto stator iron core of the present utility model comprises: corresponding superimposed stator punching group and baffle plate punching sheet, described baffle plate punching sheet is arranged on stator punching group two ends, its shape is corresponding with adjacent stator punching, described stator punching group and baffle plate punching sheet at least form a superimposed body of T-shaped coiling tooth, described T-shaped coiling tooth is superimposed is externally coated with insulation framework, to form wrapping post, the cross section of described wrapping post is the rectangle of bevelling.
Wherein, the size of some stator punchings of described stator punching group is identical.
The wrapping post cross section of magneto stator iron core of the present utility model is the rectangle of bevelling, shorter relative to the winding length of the rectangular copper wire of rounding, and the consumption of copper is less, especially reduces the consumption of copper widely when producing in batches; In addition, relative to the rectangle of rounding, the rectangle manufacture craft of bevelling is simple, and cost is lower.
Accompanying drawing explanation
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, be briefly described to the accompanying drawing used required in embodiment or description of the prior art below, apparently, accompanying drawing in the following describes is only embodiments more of the present utility model, for those of ordinary skill in the art, under the prerequisite not paying creative work, other accompanying drawing can also be obtained according to these accompanying drawings.
Fig. 1 is the structural representation of existing a kind of magneto stator iron core;
Fig. 2 is for magneto stator iron core shown in Fig. 1 is along C-C cross section structure schematic diagram;
Fig. 3 is the structural representation of a kind of magneto stator iron core of the utility model embodiment;
Fig. 4 is for magneto stator iron core shown in Fig. 3 is along A-A cross section structure schematic diagram.
Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The magneto stator iron core of the present embodiment as shown in Figures 3 and 4, comprising: corresponding superimposed stator punching group and baffle plate punching sheet 130, baffle plate punching sheet 130 is arranged on stator punching group two ends, and its shape is corresponding with adjacent stator punching 120.Stator punching group and baffle plate punching sheet at least form a superimposed body of T-shaped coiling tooth, and this T-shaped coiling tooth is superimposed is externally coated with insulation framework 110, to form wrapping post 100.In order to shorten the winding length of copper cash, reduce the consumption of copper, the cross section of wrapping post 100 is the rectangle of bevelling, especially reduces the consumption of copper widely when producing in batches.In addition, relative to the rectangle of rounding, the rectangle manufacture craft of bevelling is simple, and cost is lower.
Further, the size of some stator punchings 120 of stator punching group is identical.When wrapping post is rounding, (as shown in Figure 2) stator punching divides two groups, comprise the first stator punching 21 and slightly little the second stator punching 22 of size, therefore, add the flow process of making and assembly technology, cost is high, and easily make mistakes when assembling, cause product error rate high.The magneto stator iron core of the present embodiment only has a kind of stator punching 120 of size, can reduce by one pair of punch die, reduces by a procedure when assembling, therefore make with assembly technology simple relative to the mode of Fig. 2, cost is low, and is not easy to make mistakes when assembling, and conforming product rate is high.
Copper cash is wrapped in after on wrapping post 100, because the tension force of copper cash is comparatively large, can cause damage to insulation framework 110 (being generally plastic material).The cross section of the wrapping post 100 of the magneto stator iron core of the present embodiment is bevelling rectangle, and relative to round rectangle, the stressed of copper cash becomes eight points from four points, force dispersion, greatly reduces the damage of insulation framework 110.And each angle of bevelling rectangle is that obtuse angle (about 135 °) is also not easy the copper cash that fractures, also relatively little to the damage of copper cash.
But the magneto stator iron core multipole iron core of the present embodiment, as the magneto stator iron core of 1 pole, pole ~ 18, the cross section of each extremely corresponding wrapping post 100 is the rectangle of bevelling.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection range of the present utility model.
