Description

Combined stator structure

The invention belongs to motor component, particularly a kind of combined stator structure.

Make the stator department of the low cogging torque of a high running efficiency and rotor, it is made bottleneck and occurs in mostly on the problem of coil-winding, because high running efficiency is arranged, must there be relative Denso to carry and the magnetic loading, wherein Denso carries the thickness and the number of turn that related problem is stator coil line footpath, there is high running efficiency will have higher Denso to carry and higher current flowing just will be arranged in coil, have higher electric current that coil than thick line footpath also must be arranged, the copper cash than the thick line footpath can advance with the line resistance that reduces coil to reduce the electric power that is consumed in the coil simultaneously.(W=I ²R) W wherein: power consumption, I: motor rotation electric current, R: the impedance of coil copper cash.The above, the therefore necessary fill-in ratio that improves the wire casing coil is wound in the wire casing seat for the coil than the thick line footpath, promotes the neat coiling of the best approach of coil fill-in ratio for employing winding displacement in upright arrangement.

As Figure 12, shown in Figure 12 A, in known, outer stator structure 71 cordings have a plural number flank of tooth end 311 to be the stator teeth 31 of arcuation face, stator teeth 31 has tooth root end 312, coil portion 51 is wound in the wire casing seat,, finishes in the notch 711 of its stator slot the neat coiling of winding displacement in upright arrangement but must staying the coiling guide pin turnover stator teeth notch 711 of the coiling machinery of controlling greater than the coiling channel confession CNC of line footpath more than 2 times, the wire casing mouth must be reserved the coiling guide pin channel of line footpath more than 2 times, thereby the necessary winding space that reduces wire casing, just the wire casing fill-in ratio of winding displacement in upright arrangement approximately can only rise to 50%, desire is improved this phenomenon, therefore a kind of new manufacturing engineering method is disclosed, promptly set about the center of each wire casing is outwards cut from the iron core structure of stator department, and make cutting part have flexible binding structure, make each wire casing mouth door of stator department formation in one line open winding displacement in upright arrangement greatly for high fill-in ratio, but said method is also wideer than tooth root end because of the increment of wire casing, therefore insulate wire casing seat and coil can not wind the line outside in advance finish after again cover penetrate the stator tooth butt, but wire casing tooth root end in one line must be finished the insulation engineering, there is the guide pin horizontal synchronization coiling of CNC device to carry out the winding engineering of coil with three guide pins again, be approximately 80% with higher coil fill-in ratio after reaching the stator department combination, the winding engineering of above-described two kinds of winding displacements in upright arrangement has a common phenomenon, all must use the guide pin coiling machinery that the CNC device is arranged, winding wire also passes and is twined by the CNC mechanical guiding via coiling guide pin endoporus.Desire to be applied to the operational environment of low-voltage and high-current when motor or generator, this moment, generating or running efficiency such as desire promoted the coil that then must use than the thick line footpath, in the hope of the copper cash impedance that reduces coil and then reduce power consumption among coil, but than the coil in thick line footpath when directly being wound in the wire casing seat, inevitable coiling torsion because of the machinery that winds the line makes the wire casing seat of plastic raw materials moulding produce deflection, and then influences the mechanicalness precision after the wire casing seat entire combination.The stator department of known motor or generator has improved the fill-in ratio of wire casing interior loop because of winding displacement in upright arrangement, therefore promote effectively running or generating efficiency, but also therefore make the mechanical cost of investment of whole coiling significantly increase, and the coiling production cost becomes very high, so that indirect reaction does not meet the economies of mass production benefit to the unit price cost of each motor or generator with raising.

Twine manufacturing engineering with the CNC mechanical guiding, caused problem what follows:

1, because of being that high precision CNC controls, the precision and the manufacturing cost of the tool that therefore winds the line will promote.

2, because of being that high precision CNC controls, degree of difficulty height, so operating personnel's quality must improve, and thereby cause and be difficult for cultivating and the raising of salary cost.

3, the thickness in coiling line footpath will influence the size of CNC machinery coiling torsion, and therefore big coiling torsion will make guide pin hole wall mechanical structure intensity generation problem, cause plant equipment to produce difficult for the coiling engineering in thick line footpath too.

4, machinery is controlled the threading speed of coiling guide pin too slow (60～800rpm) will be caused production efficiency too low.

5, because of being to adopt CNC precise winding machine tool, its equipment investment cost is very high, and (the about yen 6,000,000 of coiling machinery～1,000 ten thousand circles), so the manufacturing cost that motor is arrived in indirect reaction will improve.

The purpose of this invention is to provide a kind of efficient height, the rotor cogging torque is low, equipment investment is low, reduce manufacturing cost, simple combined stator structure winds the line.

The present invention includes stator ring portion, plural number stator teeth, a plurality of insulation wire casing seat and plural coil portion; Stator ring portion system is a material and with the moulding of punching press stack with the magnetic conduction silicon steel sheet, ring end due to ring portion is divided into all angles of a plurality of isometric circles and encircles a plurality of grooves that inlay of extreme direction depression to another according to the stator number of teeth, and the width that inlays the groove inside groove must be greater than the width that inlays the groove notch; It is material and with the moulding of punching press stack with the magnetic conduction silicon steel sheet that tool is stator teeth system that the arcuation face props up flank of tooth end, the end of its tooth root end tooth root tail end that stretches out, the width of tooth root tail end inner end must be less than the width of tooth root tail end outer end, and inlay the corresponding shaping of groove with the stator ring portion, both also inlay combination each other, and tooth root tail end outer end Breadth Maximum must not be greater than the width of tooth root end; A plurality of insulation wire casing seats vertically are provided with the vertical styletable that wears winding around portion, and the interior middle vacancy of vertical styletable provides with stator teeth tooth root end is corresponding each other agrees with, and can be for the wire casing seat hollow end that wears due to the tooth root end.
