Detailed ways

Please refer to FIG. 4 , which shows a basic form of a stator 90 for a motor or generator according to the present invention. This embodiment has three stator units 10 , wherein the stator unit 10 mainly includes a columnar body 19 and a coil 30 . Regarding the columnar body 19, please refer to FIG. 1 together. For the convenience of the following description, the more detailed definition of the columnar body 19 is as follows. The columnar body 19 extends longitudinally from its top side 16 to its bottom side 17, the extending direction is defined as the longitudinal axis 41, and the columnar body 19 is roughly divided into a first end zone 11, a second end zone 12 and a middle section Zone 13, wherein the first end zone 11 and the second end zone 12 are respectively connected to both sides of the middle zone 13 (the N pole and the S pole are formed after the coil is wound and energized), and approach the inner side 14 of the monomer 10, and the inner side The opposite side of 14 forms the outer side 15 .

As for the material of the columnar body 19, it needs to be a magnetically conductive material, such as powder metallurgy, or as shown in Fig. 2 with a plurality of magnetically conductive plates 20 stacked along the longitudinal axis 41, or as shown in Fig. The direction from the inner side 14 to the outer side 15 is stacked, and the magnetically conductive plate 20 can be made of a magnetic electromagnetic steel sheet or other magnetically conductive materials.

In addition, a coil 30 (such as an enameled copper wire) that is conductive and has an insulating layer on the outer layer is wound on the columnar body 19, wherein the coil 30 is wound through the top side 16, the inner side 14, the bottom side 17 and the outer side of the columnar body 19 multiple times. 15. In addition, the cylindrical body 19 is preferably provided with a coil seat 31 for winding the coil 30 .

The embodiment of Fig. 4 shows that the winding position of the coil 30 is located at the first end zone 11 and the second end zone 12, and the stator monomers 10 are arranged around the mover 91 of the motor or generator in a neat manner, and each stator monomer The inner sides 14 of 10 all face the central axis 93, and the surrounding axis is defined as the central axis 93, and the central axis 93 is also the axis of rotation of the mover 91 to form a six-pole (three N poles, three S poles ) of the stator 90.

The difference between FIG. 5 and FIG. 4 lies in that the wire pattern 30 is wound around the middle section 13 , and the first and second end sections 11 and 12 are processed into concave arcs 18 for tight engagement with the mover 91 .

Figure 6 shows a motor stator composed of six stator cells 10, wherein the coil 30 is wound at the first end region 11 and the second end region 12, but the coil 30 connects the end regions of each adjacent stator cell 10 Wrap together.

Figures 7 and 8 show that the stator monomers 10 are distributed in three layers with the central axis 93 extending, and each layer of stator has a monomer 10 to form a stator 90 with six poles. In order to make the six poles equidistantly arranged, Each layer of stator cells 10 has a potential difference with respect to the longitudinal axis 41 (for example, the positions of the stator cells 10 of each layer are different with respect to the longitudinal axis 41 ).

Figures 9 and 10 show that the stator monomers 10 are distributed in two layers in terms of the extension of the central axis 93, and each layer of stator has three monomers 10 to form a stator 90 with twelve poles, so that the twelve poles are equally spaced Arrangement, the stator monomers 10 of the lower layer just cross the stator monomers 10 of the upper layer.

The longitudinal axis 41 of each stator element 10 of the embodiments shown in FIGS. 4-10 above is parallel to the central axis 93 .

Please refer to FIGS. 11-13 showing an embodiment in which the longitudinal axis 41 of each stator unit 10 is perpendicular to the central axis 93 . Please refer to Figures 11-12 showing that six stator units 10 form a stator 90 with twelve poles (reference N poles and S poles are marked as shown in the figure) around the central axis 93 at intervals of 60 degrees. In this situation The lower mover 91 can adopt a magnet whose magnetic poles are staggered obliquely as shown in Figure 16, or it can be divided into two magnets but the magnetic poles are staggered as shown in Figure 18, or the upper and lower two-layer aluminum die-casting mover 91 (non-permanent magnet). FIG. 13 shows a two-layer arrangement based on FIGS. 11-12 . Of course, the stator cells 10 on the lower layer can also be arranged crosswise with the stator cells 10 on the upper layer (not shown).

14-15 show the condition that the longitudinal axis 41 of each stator unit 10 forms an angle θ with the central axis 93. The advantage of this arrangement is that the coil 30 is easier to arrange and wind a little thicker.

Please refer to FIG. 19 again to show another arrangement of the stator monomers 10, the longitudinal axis 41 of the three stator monomers 10 (six poles) is an embodiment perpendicular to the central axis 93, and the inner side 14 of the stator monomers 10 faces The direction is parallel to the longitudinal axis 41 . At this time, the mover 91 is in the shape of a disc and is connected with the fixing device 50 through the bearing 911 and the shaft 912. The mover 91 has magnets 913 (six poles) arranged around the periphery, so that the mover 91 can rotate accordingly.

In order to fix the plurality of stator monomers 10 described in the above-mentioned embodiments, the stator 90 needs a fixing device 50, the structure of which fixing device 50 can be a shell, and the plurality of stator monomers 10 are fixed by adhesion, screws or welding. Fixing on the casing, or arranging a plurality of stator monomers 10 on a shelf and then integrally forming them in the form of plastic potting, since there are quite a variety of known technologies for the fixing device 50, and it is not the focus of the present invention, so here No longer.

It should be noted that the above are only examples, and the scope of rights claimed by this patent should be based on the scope of the patent application, rather than being limited to the examples.
