Description

Stratiform annular film winding type motor and technology

The invention belongs to the electrical engineering technical field.Specifically, be a kind of new film winding fabrication techniques that adopted, have novel armature structure and be rotor structure, DC generator and motor.

At present, the motor that removes individual types is as, faraday disk DC generator, because its armature or rotor just are made of single rosette, do not have winding wire, thus manufacture craft very simple beyond, the making of all the other all kinds of motors all need be used the armature winding technology of loaded down with trivial details complexity.And because the used winding conducting wire of its armature winding must have certain mechanical strength, diameter is thicker, can't a large amount of winding wire of intensive layout on the armature of this motor, or reach the purpose that significantly improves power of motor and efficient.For the superconducting wire of fragility, can't carry out the winding operation especially.Such large-size machine is forced to adopt powerful armature supply in order to improve its power output.Thereby internal resistance, in-fighting are big, the cooling cooling difficulty.As for faraday disk DC generator, though armature structure is simple.But power output is too little; Operational efficiency is lower.The maximum power that whole rosette can be exported or change only can be equivalent to the power that a straight lead that waits radius is produced under identical rotating speed and field intensity.Thereby there is not the value of practical application basically.

The present invention is directed to the problem of above-mentioned existence, adopt existing various possible film producing process as, plating, evaporation, calendering, spraying, grinding, chromatography, precipitation or the like, motor is made similar faraday disk direct current machine, armature structure is by some circular ring metal films, puts by the separate layer of some insulation interlayers is stacked; And each layer film has all been delineated into some annulus radial straight lead radially again, and stratiform annular armature to reach intensive armature winding, increases the purpose of winding wire length.The metal collector ring of inside and outside two edge on rotating shaft by its metal or the armature annulus, the radially straight lead in all each layer films can be communicated with the external world simultaneously, to constitute winding loop.Below main by describing the structure and the manufacture craft of laminate annulus armature of the present invention, illustrate substance of the present invention;

As Fig. 1, promptly shown in the vertical section schematic diagram of motor of the present invention, the 1st, its stratiform annulus armature; And just as shown in FIG., its operating current I flows to (or flow out) stratiform annulus armature by its rotating shaft 2, and along its Radial Flow.The magnetic field magnetic line that its stator or field core 3 are produced is perpendicular to the armature circular planes.

Fig. 2, Fig. 3 and Fig. 4 are respectively schematic perspective view, vertical section schematic diagram and the partial perspective cutaway view of stratiform annulus armature 1 of the present invention.Wherein, single hachure 4 those shown are the straight lead of radial film; 5 on slur line is its inside and outside collector ring.This two ring connects an end of all each straight leads in the armature separately simultaneously, to constitute winding loop in parallel.The 6th, the insulation interlayer.

For large-scale, high-speed electric expreess locomotive of the present invention, in order to solve resistance, the wear problem of exchange flow ring surface on its annulus armature, and possible sparkover problem, can cancel inside and outside collector ring, and the perspective of the sectional perspective by stratiform annulus armature circuitous path shown in Figure 5, with the straight lead of all films in the annulus armature, be one group with adjacent two layers, be communicated with in regular turn, to constitute in-line winding loop.And two layer conductors should each radially be handed over into reverse small angle with it, make to make things convenient for technology.But iff all straight leads of connection like this, two then adjacent layer conductors are boundary's electric current or following moment or the electromotive force that is produced of torque outside, will cancel out each other.Whole motor can not generate electricity or do work.At this moment, should adopt the magnetic field shielding pipe shown in the slur line 7 or 8 among Fig. 6, alternately to shield one of two adjacent in stratiform annulus armature layer conductors.Among this figure, 7,8 indication persons are respectively the magnetic field shielding pipe under vertical section and the cross section situation; The 9th, the cross section of the straight lead of film, and the wherein sensing of electric current turnover.In stratiform annulus armature of the present invention, the circuitous of lead can also adopt alternate manner.But the equally essential magnetic field shielding pipe that adopts points to or deviates from one of two parts winding conducting wire of rotating shaft to shield in the annulus armature sense of current fully.Circuitous manufacture craft in the following mask body introduced layer shape annulus armature:

One, choose suitable paramagnetic material, be made into the annular thin slice.One of in the inner edge and the outer rim of thin slice, or inside and outside two edge, should leave one or two projection, to arrange the tie point of lead.Give regularly when the size of annulus external diameter, there is an optimum value in the size of its internal diameter, can be so that the film winding wire of unit length net power that exported or conversion reaches maximum; Corresponding internal resistance in-fighting is then minimum.For the stratiform annulus armature that adopts collector ring, sheeting can freely be chosen, and needn't adopt paramagnetic material.

Two, with the method for evaporation or spraying,, make permanent insulation cuticula such as paint film, to prevent paramagnetic sheeting conduction in two sides of A, B of above-mentioned annulus thin slice (inside and outside two edge that can comprise this thin slice).If itself insulate paramagnetic material, this procedure can save.

Three, the A of annulus thin slice face sticker one deck be easy to remove as, the provisional mask film that can tear off gently as, pressure sensitive membrane or photoresist film or the like.

Four, delineate radial straight-line groove at the A of annulus thin slice face.Fluted orientation should with annulus radially slightly be little angle; The degree of depth that groove is carved in sheeting should surpass the projected depth of the straight lead of aforementioned film.And the width of groove should be narrow as much as possible; Spacing between groove should be wide as much as possible.For the armature that adopts collector ring, can delineate groove on its thin slice.

Five, on thin slice A face fluted two ends punching, promptly as the vertical core of 15 indications among Fig. 5, with the break-through thin slice.The groove location of specifically not drawing among this figure.The mode of punching can be mechanical, also can be optical lasers.

Six, evaporation insulation paint film is to cover in four, five these two procedures, because the paramagnetic material that delineation and punching are exposed again.

Seven, with methods such as evaporation, plating, make metallic film or superconducting thin film, with the whole A face of cover sheet, comprise the inner surface of each vertical core.

Eight, make the straight lead of film at the B of thin slice face.The width of this lead should be big as much as possible; Spacing between lead should be as much as possible little.And should just align with vertical core 15 in the two ends of lead.

Nine, remove or tear off mask membrane material residual on the thin slice A face.

Finish after the above operation, can obtain one group by the straight lead of double-layer films, lead thin slice that circuitous structure forms or superconducting line thin slice.Pile up successively when some such thin slices and to put, and after being communicated with in regular turn, can obtain stratiform annulus armature of the present invention.

By foregoing as can be known, the target of thinking of the present invention is to dwindle the size of armature winding wire, to reach intensive and to increase winding wire length, the purpose of reduction armature supply intensity.Same thinking also can be used for the solenoidal making of armature winding and magnetic field of other type.Such as, in Fig. 7, solenoidal winding wire 10 is exactly to adopt above-mentioned coating process, film like lead or the superconducting line made on paramagnetic thin-wall circular tube metal or nonmetallic.When some diameters successively decrease or this thin-wall circular tube that increases progressively fit layer by layer successively, and be communicated with after all connector lugs of 11 indications, can obtain magnetic field solenoid equally efficiently.It is floating as, magnetic that such solenoid can also be used for other technical field.

Advantage of the present invention is: 1, aspect motor properties, because a little less than its armature operating current, internal resistance, in-fighting are low, the power of motor and voltage can be very high; 2, in the configuration aspects of motor, the volume and weight of its unit power is all less, can be equipped with cooling infrastructure, and DC commutator and transformer etc.Therefore, motor of the present invention is actually a kind of accurate superconducting motor.3, at the design and processes manufacture view of motor, design of Windings is simple, and technology is easily manufactured; Started a kind of new, produces super-huge solenoidal with microminiature high efficiency motor and magnetic field, large-scale industrial production technology.
