Abstract

The utility model relates to a stator iron-core of a motor, which is composed of a plurality of single stacking blocks. Each single stacking block is provided with at least one bulge, at least one concave groove part, and at least a tooth part which is coated with an insulating thin layer and is wound with a coil. The bulge of each single stacking block is mutually correspondingly embedded with the concave groove part of the other single stacking block.

Description

Motor stator iron core

The utility model relates to a kind of motor stator iron core.

Existing motor stator iron core as shown in Figure 1, this iron core 1 piles up riveted mutually by multi-disc lamination 11 (silicon steel sheet) and forms, this lamination 11 is one to have the hollow circular ring of several tooth portions 12 and slotted eye 13.Existing motor stator iron core, because its lamination is complete a slice, when being made into iron core, and when using this iron core and manufacturing motor stator, following shortcoming appears respectively: (a) need can form a complete lamination with big punch press and big die stamping the cost of investment height of big punch press and big mould; When (b) inserting the insulating paper sheet in the slotted eye, must use special-purpose paper-inserting machine to insert special-purpose paper-inserting machine complex and expensive by groove; When (c) coil is gone into slotted eye, be pressed in each slotted eye of stator with special-purpose lambda line machine again after with copper cash coiled coil earlier with general coil winding machine, special-purpose lambda line machine costliness, the iron core two ends must stay unnecessary coil behind the lambda line, and cost is high and do not have economic benefit, and the lambda line mode because of the lambda line machine can't make the copper cash fill-in ratio of the slotted eye of stator improve again, relative efficiency can not improve, and need pile up thicker stator core, and could improve whole horsepower, cost increases; (d) need integer again behind the lambda line, need to use special-purpose reshaper, special-purpose reshaper costliness; (e) though lambda line through integer, it is a lot of that the coil two ends still exceed iron core, needs once more the integer wiring to fix, wiring need use special-purpose wire binding machine, special-purpose wire binding machine costliness.As seen, the amount of money that the making of existing motor stator need be invested is huge and operation procedure is various, and resulting product exists that efficient is not high, characteristic can't be brought into play with all strength, more or the like the many shortcomings of waste of material.

The purpose of this utility model is to provide a kind of motor stator iron core, and it is produced easily, and investment goods is few.

According to the motor stator iron core that the utility model provides, this iron core is made of the monomer stacked blocks that several have at least one protuberance and at least one concave part, and the protuberance of each monomer stacked blocks is corresponding chimeric mutually with the concave part of another monomer stacked blocks.

Now enumerating embodiment and conjunction with figs. specifically is described below above-mentioned purpose of the present utility model, feature and other effects and advantage.

Fig. 1 is the schematic diagram of existing motor stator iron core.

Fig. 2 piles up the block structured schematic diagram for a monomer of the present utility model.

Fig. 3 is the schematic diagram of the utility model motor stator iron core.

Fig. 4 is that a monomer stacked blocks of the present utility model is in the schematic diagram of tooth portion winding around.

Fig. 5 is the embodiment schematic diagram of motor stator of the present utility model.

See also shown in Figure 2ly, monomer stacked blocks 2 of the present utility model piles up riveted by several monomers 20 and forms, and this monomer stacked blocks 2 has a protuberance 21, a concave part 22 and a tooth portion 23.

See also the utility model motor stator iron core shown in Figure 3, this iron core is made of several monomer stacked blocks 2, the concave part 22 of the monomer stacked blocks 2 that the protuberance 21 of each monomer stacked blocks 2 is adjacent with another is corresponding chimeric mutually, so forms a complete motor stator iron core.

See also shown in Fig. 4,5, the making of motor stator of the present utility model can coat an insulating paper 4 in tooth portion 23 by monomer stacked blocks 2, and winding around 5, the monomer stacked blocks 2 that again several is wound with coil 5 is corresponding chimeric mutually, thereby forms a motor stator (as Fig. 5) that is wound with coil.

The utility model motor stator iron core is partitioned into several monomer stacked blocks, have following advantage: (a) monomer relative one complete lamination only is small pieces, it can little punch press, little die stamping, need not use expensive big punch press and big die stamping, reduce the cost of production equipment greatly, monomer also can be stacked into a monomer stacked blocks; (b) monomer stacked blocks coated insulation paper is easy, needn't purchase special-purpose paper-inserting machine in addition; (c) can have general coil winding machine now and directly do saturated and neat coiling, need not to use expensive special-purpose coil winding machine, adopt general coil winding machine once a plurality ofly to wind the line simultaneously, work is fast convenient, can neat and saturated coiling reach high saturation magnetic field again, can save the long-pending thick of enamelled wire and lamination (silicon steel sheet), in brief, under identical iron core thickness, the utility model motor stator iron core is more efficient than existing motor stator iron core.

Each motor manufacturing works makes loaded down with trivial details because of motor stator at present, especially each equipment all is normalization, as when wanting conversion to produce another machine, equipment in the plug wire machine in source, lambda line machine, reshaper, wire binding machine or the like a series of special machines all will be changed, time-consuming expensive again, the adjustment time is long and loss is big during the conversion machine; The utility model then can overcome its shortcoming, especially the research and development of the production of a small amount of multimachine kind or motor, the new machine of generator is had more cheaply again speciality fast.

In sum, the utility model motor stator iron core really can reach the creation purpose by the structure that is disclosed, and has progressive ground utility function; And the above person only is preferred embodiment of the present utility model, and various modifications and variation that all foundations spirit of the present utility model is done must be contained in the claim scope of the present utility model.
