Further specify preferred embodiment of the present utility model in conjunction with above-mentioned each accompanying drawing now, please refer to Fig. 4 and be the stator that is used for motor or generator 90 according to the utility model one citation form, present embodiment has the monomer 10 of three stators, and wherein the monomer 10 of stator mainly comprises column 19 and coil 30.Relevant column 19 please in the lump with reference to figure 1, for convenient explanation thereafter, is defined as follows these column 19 thinner portions.This column 19 is to be prolonged by its top side 16 to extend longitudinally to its bottom side 17, this prolongs vertical direction and is defined as longitudinal axis 41, and this column 19 slightly is divided into first petiolarea 11, second petiolarea 12 and stage casing district 13, wherein first petiolarea 11 and second petiolarea 12 are linked to the both sides (winding around and energising back form the N utmost point and the S utmost point) in stage casing district 13 respectively, and the inboard 14 towards monomer 10 is close, and inboard 14 opposite side forms the outside 15.

Be required to be the material of magnetic conduction as for the material of column 19, make as powder metallurgy, perhaps longitudinally axis 41 is folded mutually forms with a plurality of magnetic conductive boards 20 as Fig. 2, or figure as Fig. 3 by a plurality of magnetic conductive boards 20 by inboard 14 to the outside 15 directions fold mutually and form, wherein magnetic conductive board 20 can adopt as magnetic electromagnetic steel sheet or other and have the material of magnetic conduction.

Can conduct electricity in addition and outer coil 30 (as enamel covered wire) with insulating barrier, be to be wound in column 19, wherein coil 30 is the top sides 16 of repeatedly twining by column 19, inboard 14, the bottom side 17 and the outside 15, column 19 preferably is provided with coil holder 31 with winding around 30 in addition.

The embodiment of Fig. 4 shows that the position that coil 30 twines is to be positioned at first petiolarea 11 and second petiolarea 12, and the monomer 10 of stator is to arrange around the mover 91 of motor or generator in neat mode, and the inboard 14 of the monomer 10 of each stator is all towards central axis 93, and the axis that is centered on is defined as central axis 93, this central axis 93 also is the axis of mover 91 rotations, to form a stator 90 with sextupole (three N utmost points, three S utmost points).

Fig. 5 and Fig. 4 difference are that coil 30 is wound in stage casing district 13, and first and second petiolarea 11,12nd, through being processed into concave arc 18 so that with mover 91 fluid-tight engagement.

Fig. 6 shows and to form a motor stator by the monomer 10 of six stators, and wherein the position of coil 30 windings is to be positioned at first petiolarea 11 and second petiolarea 12, but the petiolarea of the monomer 10 of coil 30 stator that each is adjacent twines together.

Fig. 7, Fig. 8 show that the monomer 10 of deciding son with central axis 93 extensions is distributed in three layers, each layer stator all has a monomer 10 to form a stator 90 with sextupole, for this sextupole is equidistantly arranged, the monomer 10 of each layer stator all has potential difference (as the monomer 10 of each layer stator with the equal difference in longitudinal axis 41 positions) with longitudinal axis 41 positions.

Fig. 9, Figure 10, son is decided in demonstration with central axis 93 extensions monomer 10 is distributed in the second layer, each layer stator all has three monomers 10 to form a stator 90 with 12 utmost points, for this 12 is extremely equidistantly arranged, the monomer 10 of the stator of lower floor just with monomer 10 cross arrangements of the stator on upper strata.

Above Fig. 4 to Figure 10, the longitudinal axis 41 of the monomer 10 of each stator of embodiment of demonstration is parallel with central axis 93.

Ask for an interview Figure 11 to Figure 13, the longitudinal axis 41 that shows the monomer 10 of each stator is embodiments vertical with central axis 93.Ask for an interview Figure 11 to Figure 12, the monomer 10 that shows six stators forms one with 60 degree of whenever being separated by around central axis 93 and has the then stator 90 of (the N utmost point of reference and S pole marks show as graphic shown in) of 12 utmost points, can to adopt as Figure 16 magnetic pole be oblique staggered magnet to mover 91 under this situation, or be divided into two blocks of magnet but pole arrangement is staggered, or as two layers of aluminium die casting mover 91 (impermanent magnet) up and down of Figure 17 as Figure 18.Figure 13 then shows based on Figure 11 to Figure 12 but is the situation of two-layer arrangement, certainly the monomer 10 of the stator of lower floor also can with stator monomer 10 cross arrangements (figure does not show) on upper strata.

Ask for an interview Figure 14 to Figure 15, show longitudinal axis 41 and central axis 93 situation of θ at angle of the monomer 10 of each stator, the benefit of this arrangement is that coil 30 is easier to arrange to twine thicker.

Refer again to Figure 19, show the monomer 10 another kind of arrangement modes of stator, the longitudinal axis 41 of the monomer 10 (sextupole) of three stators is embodiments vertical with central axis 93, and the direction of 14 courts in inboard of the monomer 10 of stator is parallel with longitudinal axis 41.This moment, mover 91 one-tenths one disc-shapes saw through bearing 911 and axostylus axostyle 912 links with fixture 50, and wherein mover 91 has magnet 913 (sextupole) and is arranged in periphery, made therefore rotation of mover 91.

For the monomer 10 of the described a plurality of stators of the foregoing description is fixed it, stator 90 needs fixture 50, the structure of this fixture 50 can be a shell, and with sticking work, be fixed on the shell with screw or welding manner monomer 10, or the monomer 10 of a plurality of stators be arranged on the shelf to irritate the mode of mould with plastic cement integrally formed again, because fixture 50 is that the known technology kind is quite multiple a plurality of stators, yet non-emphasis of the present utility model is not so repeat them here.
