Description

Motorcycle magneto stator core

Technical field

The utility model relates to a kind of magneto, is specifically related to a kind of motorcycle magneto stator core.

Background technology

Motorcycle mainly is made of stator and rotor with magneto, wherein stator includes stator core and coil, usually superimposed and be riveted together and constitute stator core by several stator punchings, because the structure of stator punching is that the middle part is an installation portion, outer rim is equally distributed T type coiling tooth, the iron core outer rim of superimposed formation forms the coiling tooth of T shape, and at the outer surface injection moulding insulating material of iron core, winding around constitutes the magneto stator on the coiling tooth of stator core outer rim at last then.Owing to form the stator punching of stator core, it is measure-alike, therefore the wrapping post cross section on its coiling tooth mostly is rectangle, in order to reach required area coil, make that the thickness of iron core is thicker, it is longer that Heavy Weight, copper cash are wound on the rectangle wrapping post girth, bending is bigger, so the copper cash consumption is many, the damage big, cost is high.Chinese patent (ZL200820100297.9) discloses a kind of magnetic motor for motorcycle stator core, its stator punching is the wideest according to the coiling tooth of middle punching, both sides are that the benchmark symmetry width that successively decreases is arranged with middle punching, be overlapped into the form of polygon prism, then polygon prism is carried out injection moulding, form the winding structure of polygon prism; Though this kind structure is wound in required area coil, the copper cash of its use and the consumption of iron core reduce to some extent, still have the big problem of copper cash bending damage; Simultaneously, because the stator laminating structure of half all changes to some extent, the cost of processing and assembling is all than higher.

The utility model content

The technical problems to be solved in the utility model is: provide that a kind of copper cash consumption is few, the bending damage is little, again the lower motorcycle of processing cost magneto stator core simultaneously.

In order to solve the problems of the technologies described above, the utility model provides a kind of motorcycle magneto stator core, includes corresponding superimposed stator punching group, baffle plate punching and insulation framework; Wherein, the main part of stator punching is an octagon, and its each middle part, bar limit is provided with a T type coiling tooth; Described baffle plate punching is arranged on stator punching group two ends, and its shape is corresponding with adjacent stator punching; Described insulation framework is coated on the superimposed body of coiling tooth of stator punching group and baffle plate punching formation, and the cross section of the wrapping post that superimposed body of described coiling tooth and insulation framework form is a round rectangle.

Adopt the motorcycle of technique scheme to have following advantage: because the coiling cross sectional shape that coiling superimposed body of tooth and insulation framework form is a round rectangle with the magneto stator core, it changes less to stator laminating structure, the cost of processing and assembling is all lower, and than the wrapping post of rectangle and polygon prism, its bending damage to copper cash is little, the more important thing is that under needs wind the line the situation of area equally its coiling girth shortens, and has reached the purpose of saving copper wire material.

Improvement as technical solutions of the utility model, the width of the stator punching coiling tooth at described stator punching group middle part is identical, the coiling facewidth degree symmetry of the stator punching at its two ends is successively decreased, add like this and can only change man-hour a spot of stator laminating structure, be convenient to realize standardization, save processing cost.

Embodiment

Below in conjunction with drawings and Examples technical solutions of the utility model are further specified:

Embodiment 1

As shown in Figure 1, Figure 2, Figure 3 and Figure 4, the utility model provides a kind of motorcycle magneto stator core, includes corresponding superimposed stator punching group, baffle plate punching 2 and insulation framework 3; Wherein, stator punching 1 is a chip integrated punching structure, and the main part 11 of stator punching 1 is an octagon, and its each middle part, bar limit is provided with a T type coiling tooth 12, baffle plate punching 2 is arranged on corresponding superimposed stator punching group two ends, and the shape of baffle plate punching 2 is corresponding with adjacent stator punching 1; The winding portion width of the coiling tooth 12 of the stator punching 1 at stator punching group middle part is identical, and the winding portion width symmetry of the coiling tooth 12 of corresponding superimposed stator punching group two ends stator punching 1 is successively decreased, and the winding portion of coiling tooth 12 superimposed bodies presents round-corner transition; Insulation framework 3 is coated on the superimposed body of coiling tooth of stator punching group and baffle plate punching 2 formations, and the cross section of the wrapping post 5 that coiling superimposed body of tooth and insulation framework 3 form is a round rectangle.

Coiling tooth 12 superimposed bodies form round-corner transition, no seamed edge, and it is round rectangle that insulation framework 3 coats the back wrapping post, than the wrapping post of rectangle and polygon prism, its bending damage to copper cash is little, under the situation of same coiling area, its coiling girth shortens, and saves copper wire material.

Above-described only is preferred implementation of the present utility model; should be understood that; for a person skilled in the art; under the prerequisite that does not break away from the utility model structure; can also make some distortion and improvement; such as the quantity of stator punching in the fillet size that simply changes the superimposed body of coiling tooth, the adjustment stator punching group, these also should be considered as protection range of the present utility model, and these can not influence effect and practical applicability that the utility model is implemented.
