0-1~10-3 is please referred to Fig.1, Figure 10-1 is the first winding 200 ' and the signal of slot for winding 100b ' Insulation Coordinations Figure；Figure 10-2 is second of winding 200 ' and the schematic diagram of slot for winding 100b ' Insulation Coordinations；Figure 10-3 is the third winding 200 ' With the schematic diagram of slot for winding 100b ' Insulation Coordinations.

As described above, after the embedded slot for winding 100b ' of winding 200 ', insulation processing can be carried out, with AC low-tension motor around Illustrated exemplified by the insulation system of group 200 '.The rated voltage of AC low-tension motor is generally below 3KV, often have 380V, Several grades such as 660V, 1140V.AC low-tension motor insulation structure includes turn-to-turn insulation c ', slot insulation a ', layer insulation b ' (structure for being directed to Double Layer Winding 200 '), phase insulation and lead wire insulation (not shown) etc..Illustrated respectively below：

(1) turn-to-turn insulation c '：Random-wound coils 200 ' with its electromagnetic wire (i.e.：The copper or aluminium of winding, surface are formed with insulating The conducting wire of layer) insulation of itself is as turn-to-turn insulation c ', such as enameled wire coat, glass fiber covered wire outsourcing glass fiber or film coiling Outsourcing film etc..Reference can be made to Figure 10-2,10-3 understand.

(2) slot insulation a '：Slot insulation be a ' before embedding in insertion groove, generally use Film laminated insulating materials and more Layer insulation forms compound slot insulation.The base material of Film laminated insulating materials is polyester film, after its and moisture absorption more sensitive to oxygen easily Hydrolysis, in early days with the compound composition compound inslation such as highland barley paper, varnished glass cloth.To overcome highland barley paper poor heat resistance and the easy moisture absorption makes Polyester film hydrolyzes this shortcoming, and recent year has developed polyester fiber paper and polyester film compound material (B grades), Yi Jifang Fragrant polyamide fibrous paper and composite polyimide material etc..The effect of each layer insulation of slot insulation a ' is different, close to the exhausted of cell wall Edge mainly plays mechanical protection, to prevent cell wall from damaging major insulation；Close to the work of one layer of insulating paper of the electromagnetic wire of winding 200 ' With being to prevent from damaging major insulation during embedding.And the insulation (i.e. the major insulation of slot insulation) between this two layers is to be used to bear Dielectric strength.Increase since the mechanical force that slot insulation a ' is born increases with capacity motor, so slot insulation a ' thickness is also with electricity The raising of machine capacity and voltage class and accordingly increase.

(3) phase insulation (not shown)：The end of winding 200 ' is alternate to be encased inside the composite material identical with slot insulation (DMDM or DMD).

In addition, protection insulation d ', insulation against ground e ', slot bottom filler strip f ' are also illustrated in Figure 10-3.

Please refer to Fig.1 2, Figure 12 be wind-driven generator structure in winding 200 ' and its ferromagnetic parts 100 ' by multiphase flow The schematic diagram of erosion.

Motor includes winding 200 ' and ferromagnetic parts 100 ', can form stator or rotor, as shown in figure 14, is formed default Son, periphery are equipped with rotor 600 ', and the inner circumferential of rotor 600 ' is equipped with magnetic pole 500 ', and ferromagnetic parts 100 ' are solid by radial direction fastener 102 ' Due to rack 101 '.Stator medium position is formed with busway 103 ', hot wind extraction channel 104 ', air inducing equipment 105 ', remittance Flow device 106 '.Ferromagnetic parts 100 ' are formed by multiple core lamination stack 100a ' are stacked, form some ferromagnetic parts radially extended Radial passage, the periphery of ferromagnetic parts 100 ' form ferromagnetic parts radial passage entrance s ', as can be seen from Figure 14, form following The circulation path of multiphase flow：

Nacelle exterior environment-open type air-supply passage w- ferromagnetic parts radial passage entrance s '-ferromagnetic parts radial passage-remittance Circulation road 103 ' -105 '-junction station of hot wind 104 '-air inducing equipment of extraction channel 106 '.

In the external environment of motor, there are wind, frost, rain, snow, sand and dust, salt fog, gas-liquid-solid multiphase flow, these fluid meetings Constantly circulated from above-mentioned circulation path, insulation is above-mentioned there are during problem after in the embedded ferromagnetic parts 100 ' of winding 200 ' Fluid can constantly invade and corrode insulating layer, so as to damage motor.

It may be referred to Figure 11-1~11-3 to understand, Figure 11-1 is that the signal of slit aperture occurs in the position of slot wedge 300 ' in Figure 10-1 Figure；Figure 11-2 is that the schematic diagram of slit aperture occurs in the position of slot wedge 300 ' in Figure 10-2；Figure 11-3 is the position of slot wedge 300 ' in Figure 10-3 Put the schematic diagram for slit aperture occur.After the bonding fault rupture of slot wedge 300 ' and slot for winding 100b ' notch contact positions, it may appear that one Fixed slit aperture (slit aperture axially extends, and connects the position of winding 200 ' on the inside of exterior and slot wedge 300 ').Exterior Multiphase flow can invade ferromagnetic parts 100 ', winding 200 ' along the slit aperture, damage motor.

For this reason, please referring to Fig.1 3, Figure 13 is the schematic diagram of slot wedge 300 ' of reinforced insulation.I.e. in slot wedge 300 ' and slot for winding Between the side wall of 100b ' set thermal expansion leak sealing part 300a ', thermal expansion leak sealing part 300a ' can strengthen slot wedge 300 ' with around Sealing between group groove 100b ', prevents external fluid from invading.

Therefore, it is necessary to prevent external fluid from invading, ensure insulation effect.But above-mentioned insulation dipping lacquer processing, still can not Insulating reliability is solved the problems, such as, as shown in Figure 11-1~11-3.

Traditional paint-dipping process, mainly vacuum pressed dipping lacquer (VPI) technique.The technical process is as follows：

In VPI methods, the object that will be impregnated first is placed in the containing vacuum secret room that pressure is about 1mbar.Connect Get off, the resin for being pretreated (viscosity inspection, addition curing agent, cooling) and degassing being placed in autonomous container, through heat exchange Device is heated to tens degrees Celsius, such as：70 DEG C, then transported by pump into vacuum chamber, until impregnated object is warmed completely Resin flood (submergence) and cover.

The preheating of resin is extremely important, because it can significantly reduce resin viscosity, so that resin can more easily enter With slit aperture in filling slot.Then vacuum is discharged, close room pressure is added to 3-5bar (bar, pressure unit), it is small to stagnate number When.Finally, resin is pumped back in cold containers by heat exchanger, and resin is cooled down in storage container, this is for unhardened Resin life is extremely important.Subsequently the object of dipping is placed into baking oven, heat is dried hardening of resin, cured.

Why it is difficult to reach reliable insulation effect, in mainly current paint-dipping process, there are following contradictions：

The viscosity and quantity of solvent of paint have relation, and solvent is more, and solids content is fewer, and the viscosity of paint is lower.If use The paint of low viscosity, the penetrating power of paint is strong, each gap that winding 200 ' can be penetrated into well, gap between layer of solid insulating material Mouthful, the slit aperture of solid insulating material institutional framework (such as：Porous material) in；But the low paint of viscosity, the content for painting base are just lacked, After solvent volatilization, the gap left is more (gap is to cause so-called breathing phenomenon to exist, destroy the root of insulation), makes Its moisture protection, the capacity of heat transmission, mechanical strength and dielectric strength are all affected.If the paint viscosity used is excessive, paint is difficult It is internal to penetrate into winding 200 ', that is, " oozing impermeable " occurs, moisture protection, the capacity of heat transmission, mechanical strength and electrically by force Spend requirement of equally arriving.

For this reason, the motor of domestic electric machine factory production at present generally uses secondary dipping lacquer.Adopt the technology that heat sink soaking technology, It is 2 times to dry number.The process of dipping lacquer is painted by preliminary drying, first time dipping lacquer, drop paint, drying for the first time, second of dipping lacquer, drop, the Secondary drying.During first time dipping lacquer, in order to make paint preferably be filled into, winding 200 ' is internal, and the time of dipping lacquer should be longer； Second of dipping lacquer on the other hand, if the time of second of dipping lacquer is too long, on the contrary will primarily to formation surface film First time dipping lacquer paint film damages, the dipping lacquer effect that cannot be got well.Time scale is there is also contradiction during drop paint twice, not only The number of dropouts of paint is influenced, secondary dipping lacquer iron core inner and outer round surface is had an effect on and hangs paint amount.It is small to hang paint amount, without scraping paint, still, groove is exhausted Gap is certainly existed in edge, produces the hidden danger (so-called " breathing of cellular insulant material in groove of water inlet, suction moisture damage insulation Phenomenon ").

To sum up, when traditional winding 200 ' and ferromagnetic parts 100 ' carry out insulation processing, there are contradiction, if paint energy It is enough preferably to enter, then do not stop the loss of paint；If reducing the loss of paint, paint is difficult to penetrate into well again.

In view of this, the moulding process of motor how is improved, improves machine winding and the insulation performance of ferromagnetic parts, is this Field technology personnel technical problem urgently to be resolved hurrily.

Embodiment

It is below in conjunction with the accompanying drawings and specific real in order to make those skilled in the art more fully understand technical scheme Applying example, the present invention is described in further detail.

It is a kind of structure diagram of specific embodiment of armature curing range provided by the present invention to please refer to Fig.1 4, Figure 14.

The armature of motor, including ferromagnetic parts (or magnetic conductive part) and winding 200 (i.e. coil), as shown in figure 14, iron Magnet assembly 100, also referred to as iron core, can be formed by some ferromagnetic laminates 100a are axially stacked, and ferromagnetic laminates 100a for example can be with It is silicon steel sheet or ferrite sheet, the structure of ferromagnetic parts 100 and the mode around the home of winding 200 specifically may be referred to background skill Art understands that the present embodiment is not construed as limiting.

The ferromagnetic parts 100 of armature are equipped with some circumferentially distributed to put the slot for winding 100b of winding 200, slot for winding along its The notch of 100b is radially oriented, and the notch of slot for winding 100b is radially outward in Figure 14.Slot for winding 100b length directions are parallel to iron The axial direction of magnet assembly 100, and slot for winding 100b penetrates through the perisporium of ferromagnetic parts 100 vertically.Slot for winding 100b is penetrated through in Figure 14 The periphery wall of ferromagnetic parts 100, ferromagnetic parts 100 at this time can be used as inner stator, i.e., rotor is arranged on the radial direction of armature Outside, stator are arranged on inner side, when ferromagnetic parts 100 as external stator in use, in slot for winding 100b perforation ferromagnetic parts 100 Perisporium.

Specifically, after winding 200 is placed in slot for winding 100b, it is equipped with the notch of slot for winding 100b and covers winding 200 slot wedge 300, impregnation technology (such as technique of vacuum pressure for dipping electrical, referred to as：VPI in subsequent process), it is situated between as insulation The steeping liq (i.e. filling bonding agent component at the same time in insulated paint, or insulated paint) of matter is possible to from slot wedge 300 and slot for winding Flowed out at slit aperture between 100b.

As shown in figures 15-18, Figure 15 is schematic diagram of the armature in rotary course is bakeed, wherein, four typical positions are shown The winding 200 and slot for winding 100b at place are put, is 12 points, 3 points, 6 points and 9 points of corresponding clock physical location positions everywhere respectively； Figure 16-1 is the schematic diagram of slot for winding 100b and its interior winding 200 at 12 positions, shows ferromagnetic border 100aL, winding border 200L, bottom insulation 200f；Figure 16-2 is the signal for being not embedded into winding 200 and slot wedge 300 in Figure 16-1 in slot for winding 100b Figure；Figure 17-1 is the schematic diagram of slot for winding 100b and its interior winding 200 at 3 positions, and slot for winding 100b is in horizontality, interior The steeping liq in portion has the trend to flow downward；Figure 17-2 is the enlarged diagram at 17-1 slot wedges 300；Figure 18 is 6 positions Locate the schematic diagram of slot for winding 100b and its interior winding 200, the notch of steeping liq outflow slot for winding 100b, forms overflowing liquid Q。

For this reason, the rotary roasting device in the present embodiment further includes sealing gland portion 30, notch is being just at least into rotary course for it Slot for winding 100b jets directed downwardly.

In this way, under whiff pressure effect, it can prevent steeping liq under the effect of gravity from slot wedge 300 and slot for winding Outflow in slit aperture between 100b, thus reduce armature drip after the follow-up dipping of technique of vacuum pressure for dipping electrical paint during, During rotary roasting, steeping liq is lost in along the radial direction between traditional slot wedge 300 and slot for winding 100b at slit aperture, is improved The full rate of steeping liq filling dipping after dipping, and take the lead in blocking the gap that steeping liq is lost in naturally in the process Mouthful, prevent 200 straight length portion of winding (part in slot for winding 100b) from producing hole, resistance with 100 border of ferromagnetic parts Hole is only produced between 200 straight length portion of winding and slot wedge 300, increase prevents moisture and other media intrusion in external environment Ability.Make the oxygen in air, moisture and water etc. be not easy to invade inside the insulator formed after slot for winding 100b dippings, can prolong Slow insulation system ageing process.Reduce motor and retained risk therein by moisture and water immersion, improve insulating reliability.

Figure 19 understandings are referred to, Figure 19 soaks at the ferromagnetic border 100aL for prevention ferromagnetic parts 100 behind setting sealing gland portion 30 The schematic diagram of stain fluid loss, shows that liquid is most easy to run off the mechanical function view of physical location in rotary roasting technical process. Ferromagnetic parts 100 are fixed on rack 101 by radially fixed part 102, and the middle part of armature mechanical support structure has busway 103, understand with reference to Figure 12 in background technology, the upward whiff pressure in sealing gland portion 30 destroys circulation path, prevents extraneous medium Into in slot for winding 100b.

Why it is at least to notch slot for winding 100b jets just directed downwardly, because notch it was found from the effect above description When just downward, the steeping liq in slot for winding 100b does not support, and is easiest to outwards overflow under the effect of gravity, and from notch just Position directed downwardly, to both sides circumferencial direction until left and right 90 degree of orientation (horizontal direction), the trend that steeping liq outwards overflows by Gradual change is weak, then be upwardly into notch just upward when, slot for winding 100b starts to support steeping liq, and steeping liq will lose becoming for spilling Gesture.Accordingly, it is preferred that scheme is, supply region at least covers the outer surface of the armature in the range of more than or equal to 180 degree, and supplies Region is with respect to notch just slot for winding 100b positional symmetries downward.Preferably it is slightly larger than 180 degree, because 180 degree is exactly level side To, actually can be in the presence of the trend outwards flowed although in theory, steeping liq no longer flows downward, and also suffer from The influence of centrifugal force, therefore steeping liq may still overflow slot for winding 100b, so it is big to may be configured as supply area coverage In the armature region equal to 180 degree.

As shown in figure 14, sealing gland portion 30 specifically includes the confluence chamber 31 being sequentially arranged along jet direction, pressure accumulation element 32, stores Chamber 33 is pressed, pressure accumulation chamber 33 is near slot for winding 100b.Sealing gland portion 30 further includes source of the gas, collects in gas source feed to the chamber 31 that converges, Respectively enter in each fluid passage 32a of pressure accumulation element 32, subsequently into pressure accumulation chamber 33, provided to corresponding slot for winding 100b again Pressed gas.

The chamber 31 that converges is arranged on the outermost in sealing gland portion 30, its cross section is arc-shaped, is matched with the periphery of armature, in order to realize Above-mentioned preferably to prevent steeping liq from overflowing, confluence 31 corresponding central angle of chamber is more than 180 degree, in figure circumferentially sequentially sign A, B, C, D, E, F, G, wherein, for D position correspondences in notch slot for winding 100b just directed downwardly and slot wedge 300, location A is slightly above radial water Horizontal line, confluence chamber 31, pressure accumulation chamber 33, pressure accumulation element 32 are set with the axisymmetrical where D points.

The present invention at least provides pressed gas to the slot for winding 100b of D position correspondences, specifically in Figure 14, then big to A-G In the range of semicircle corresponding slot for winding 100b be provided which pressed gas.Pressure accumulation element 32 and pressure accumulation chamber 33, with the chamber 31 that converges Form fit, and central angle are more than the arcuate structure of 180 degree.Pressure accumulation chamber 33 is labeled with M, K, J, and position correspondence is in confluence chamber 31 A, D, G.Pressure accumulation chamber 33, pressure accumulation element 32, confluence chamber 31, cross section is arc, length and 100 axis of ferromagnetic parts in axial direction Consistent to length, then sealing gland portion 30 is equivalent to " shell " for being covered in more than half region of armature circumference.

Elaborate below to the presentation mode of 30 pressed gas of sealing gland portion：

Pressure accumulation chamber 33 and the cavity that confluence chamber 31 is arc, the concrete structure of pressure accumulation element 32 therebetween can refer to figure 20-1 understands that Figure 20-1 is the schematic diagram of pressure accumulation element 32 in Figure 14；Figure 20-2 is that a fluid passage 32a is mono- in Figure 20-1 The schematic diagram of member；Figure 20-3 is the vertical view schematic diagram of Figure 20-1, is mainly used for showing the width L1 and length L2 of pressure accumulation element 32, Width L1 and the axial length of electromagnetic component 100 are roughly equal；Figure 20-4 is the left view schematic diagram of Figure 20-1, is also primarily used for The side form of pressure accumulation element 32 is shown.

Pressure accumulation element 32 has some fluid passage 32a, there is provided pressed gas through fluid passage 32a heel row to correspondence Slot for winding 100b outer surface.As shown in figs. 20-2, Figure 20-2 shows one along the axial direction of pressure accumulation element 32 to fluid passage 32a The fluid passage 32a units of (parallel to the axial direction of ferromagnetic parts 100) extension, fluid passage 32a is schematic diagram.This fluid leads to Road 32a is variable section channel, specifically scales passage, i.e., circulation area is first tapered and then flaring again, and this fluid passage 32a can To reach quick speedup ability and higher air velocity.In the converging transition speedup of scaling passage, speedup reaches throat's speed per hour If degree reaches velocity of sound, can continue speedup in the divergent segment of scaling passage and reach supersonic speed, with preferably increase gas (or Liquid) reach slot wedge 300 at energy, prevent slit aperture inside steeping liq overflow.

In order to supply to sealing gland portion 30, source of the gas is also separately set, source of the gas is especially by main pipe 41 and isocon 42 to sealing gland portion 30 Supply.As shown in figure 14, some isocons 42 of the gas flow of main pipe 41, some isocons 42 are connected to the outer of confluence chamber 31 Week, and the inside of confluence chamber 31 is connected to, some isocons 42 can be evenly distributed in the confluence chamber 31, so as to improve confession The uniformity of gas.Wherein, converge chamber 31 periphery set with the air-flow that isocon 42 connect into incoming interface 46, can be along remittance The air-flow of chamber 31 axial (parallel to axial direction of ferromagnetic parts 100) extension is flowed into incoming interface 46, in this way, multiple isocons 42 are passed through The gas of confluence chamber 31 can be more uniform.Certainly, it is also feasible that gas is directly passed through confluence chamber 31 by source of the gas by a pipeline Scheme, the present embodiment is not limited.

Every isocon 42 can set flow control valve 43, to control the gas flow for entering confluence chamber 31, improve Controllable adjustment ability.Furthermore it is also possible to set controller 5 and flow sensing transmitter 44, flow sensing transmitter 44 is arranged on gas 46 position of incoming interface or isocon 42 are flowed into, the flow signal of detection is exported to controller 5, and controller 5 is according to flow signal Control the input of flow, such as the aperture of control flow control valve 43.

In addition, multiple fluid passage 32a can be designed as：The entrance opening dimension of each fluid passage 32a is identical, and circumferentially, The outlet size of the fluid passage 32a of different circumferential positions is different, to obtain identical inlet pressure, speed, different outlets Pressure, speed.In this way, 300 outer surface of slot wedge that can be directed to the slot for winding 100b of circumferential upper diverse location is circumferential along armature Edge and ferromagnetic parts 100 between slit aperture provide different pressures gas.As shown in figure 14, D position correspondences in circumferential direction Slot for winding 100b at steeping liq be easiest to flow out, the outlet pressure of its corresponding fluid passage 32a can be maximum, and A, G Steeping liq at the corresponding slot for winding 100b of point will not flow out substantially, the outlet pressure of its corresponding fluid passage 32a can be with Minimum, the pressure of the fluid passage 32a between A-D, G-D are gradually incremented by by this.

One fluid passage 32a unit is shown, fluid passage 32a is axially extended, and jet path edge stores in Figure 20-2 Pressure element 32 radially extends, and radial section (along the radial direction of pressure accumulation element 32) is set in scaling, flow area (edge The axial axial cross section of pressure accumulation element 32) it is strip.The theory structure is according to mechanics principle, the thermodynamic principles for scaling passage It can realize the effect of certain speed-raising.

It is appreciated that in Figure 20-1, pressure accumulation element 32 includes multiple fluid passage 32a, and each fluid passage 32a is vertically Extension, jet path radially extends, and multiple fluid passage 32a are arcuately distributed, and arc is matched with armature periphery.In fact, As long as being the purpose that can be achieved to prevent slit aperture from flowing out to the notch jet of slot for winding 100b, multigroup arc-shaped arrangement is set here Fluid passage 32a, the outlet of each fluid passage 32a is mainly so that radially toward ferromagnetic parts 100, so as to radially right Accurate corresponding slot for winding 100b notches, farthest prevent steeping liq overflow using jet energy.

It will be appreciated that slot for winding 100b is from notch position (D or K positions in Figure 14) just directed downwardly, it is counterclockwise or suitable Hour hands certain angle, the trend that the steeping liq between slot for winding 100b and slot wedge 300 at slit aperture overflows gradually slow down.To scheme Exemplified by 14, in D positions, certain angle clockwise is to F positions, or certain angle is slowly connect to B location, slot for winding 100b counterclockwise It is near horizontal, a upward tangential component can be provided at this time, with suppress the overflow liquid of overflow along surface continue to Lower flowing, while component radially continues to prevent steeping liq from flowing out at slit aperture.It is it is appreciated that just directed downwardly from notch Position, along direction clockwise, counterclockwise, the jet path of fluid passage 32a can not be just radially, but with radially depositing In angle, so that whiff pressure is there are tangential component, and tangential component gradually increases.That is, what gas supply part 30 provided Gas, which can not be, just towards the notch jet of slot for winding 100b, but generally radially, produces certain tangential air pressure, beneficial to leaching Stain liquid levelling.

Based on this, on the basis of Figure 14 is understood, it can combine and refer to follow-up Figure 32, in the present embodiment, pressure accumulation member Part 32 includes the fluid passage 32a (fluid passage 32a is axially extended itself) of some circumferentially arc-shaped arrangements, fluid passage 32a can also itself arc-shaped extension, and some fluid passage 32a are axially disposed, then can obtain the section described in Figure 32. It is appreciated that in Figure 14, single fluid passage 32a is axially extended, and slot wedge 300, slot for winding 100b and therebetween Slit aperture also correspondingly axially extends, it is seen then that axially extending fluid passage 32a can preferably correspond to slit aperture, prevent Steeping liq overflows.

In fact, fluid passage 32a is except along the axially extending linear strip of armature, or around armature circumference, with Arc extends to form arc strip or other structures form in the vertical plane of armature axis direction.With Figure 20-2 Exemplified by, it is a fluid passage 32a unit axially extended, and it is axially distributed small that several can be included inside it Fluid passage 32a, multiple small fluid passage 32a axial arrangings form one group of fluid passage 32a unit, multigroup fluid passage The arc-shaped arrangement of 32a units, it is also possible.Equivalent in pressure accumulation element 32, forming the small of some crossbar arrays arrangement The flow area of fluid passage 32a, fluid passage 32a can be circular, be set in scaling passage.Since slot for winding 100b is set In the perisporium of ferromagnetic parts 100, notch radially opens up, and the trend of each fluid passage 32a is also towards the center of circle, radial arrangement.

As described above, the gas that sealing gland portion 30 provides is for preventing the steeping liq in slot for winding 100b from overflowing, so Need to provide the gas for possessing certain pressure, pass through fluid passage 32a speedups, boosting, on the one hand, can ensure multiple slot for windings 100b can be supplied targetedly, and fluid passage 32a is circumferentially distributed in Figure 14, and puff prot is radially set, further, since The speedup boosting of fluid passage 32a, can reduce the pressure demand to gas source feed pressure, reduce cost.

Under there is a requirement that, fluid passage 32a's is various informative, can understand with reference to Figure 21-1~22-2, Figure 21-1 is Another schematic diagram of pressure accumulation element 32 '；Figure 21-2 is the schematic diagram of a fluid passage 32a ' in Figure 21-1；Figure 22-1 is again A kind of schematic diagram of pressure accumulation element 32 "；Figure 22-2 is the schematic diagram of a fluid passage 32a " in Figure 22-1.

In Figure 21-1, the fluid passage 32a ' of pressure accumulation element 32, flow cross-section areas is along jet direction flaring；Figure 22-1 In, the actual internal area of fluid passage 32a " is tapered along jet direction.It is to be understood that jet direction is tapered speed-raising, And jet direction flaring then plays the role of supercharging.Then when supply gas pressure is higher, tapered scheme can be used, to improve flow velocity； And when supply gas pressure is relatively low, then the scheme of flaring can be used, with adherence pressure.Need can be supplied according to actual gas Ask, choose suitable fluid passage high setting scheme.

Further, formed please continue to refer to Figure 14, between two neighboring fluid passage 32a axially extending along pressure accumulation element 32 Passage, which can be used as heating passage 32b, due to adjacent with fluid passage 32a, heat passage 32b heating liquids Gas in passage 32a, then plays the role of supercharging, moreover, can also temperature from the row of raising to the gas of slot for winding 100b, from And be conducive to enhanced heat exchange speed, baking, fluid insulation paint cure it is energy saving.It is, it should be understood that mono- forming above-mentioned multigroup fluid passage 32a When first, since the scaling of fluid passage 32a, tapered or flaring are set, between adjacent fluid passage 32a, sky necessarily occurs Chamber, by the use of this cavity as heating passage 32b, without being separately provided the passage of heating, so as to make full use of space, meets at the same time The rapidity that heating-up temperature is adjusted.Fluid passage 32a and heating passage 32b can set multiple partition plates to be formed in housing, Can directly be integrally formed.

The above, description sealing gland portion 30 is primarily radially to the notch jet of slot for winding 100b, to prevent steeping liq Overflow, further, since slot for winding 100b is straight slot, therefore its both ends is port, and the present embodiment is also to slot for winding 100b's Make closure processing in both ends port.As shown in figure 30, it can be formed when winding 200 is placed in slot for winding 100b and protrude from slot for winding 100b The winding overhang 201 at both ends, winding 200 are enclosed along the circumferential coiling one of ferromagnetic parts 100, can formed at the both ends of ferromagnetic parts 100 Multiple winding overhangs 201,201 annular spread of multiple winding overhangs per one end.Correspond to therewith, rotary roasting device further include with The circular cowling 50 that armature is fixed, multiple winding overhangs 201 of 50 card cover annular spread of circular cowling, and block cover to slot for winding 100b's Port position.Source of the gas is supplied to the annular cavity of circular cowling 50, in this way, under gas pressure, can also prevent steeping liq edge It is axial to be overflowed out of slot wedge 300 and slot for winding 100b slit aperture.

Since circular cowling 50 is fixed with armature, then circular cowling 50 can rotate in baking process with armature, can set at this time Put gas slip ring 45.As shown in Figure 33,34, Figure 33 is the schematic diagram of gas slip ring 45 in Figure 30；The right side that Figure 34 is Figure 33 regards Figure.

Source of the gas can specifically be supplied by gas slip ring 45 to circular cowling 50, in this way, when circular cowling 50 is rotated with armature, The problems such as gas slip ring 45 interferingly can supply to circular cowling 50 from rotation, avoid pipeline from winding.

Steeping liq is prevented to overflow in the axial direction to be further ensured that, circular cowling 50 is that sealing card covers on ferromagnetic parts 100 End.Please continue to refer to Figure 32, it is notch perisporium that the present embodiment, which defines ferromagnetic parts 100 and sets the perisporium of slot for winding 100b, Since the ferromagnetic parts 100 of the embodiment are inner stator, notch perisporium is actually also the periphery wall of armature ferromagnetic component 100. Circular cowling 50 corresponds to the annular sidewall (should be correspondingly the lateral wall 501 of circular cowling 50) of notch perisporium and notch perisporium seals Connect, due to needing steeping liq at notch perisporium, so release cloth is equipped with also between notch perisporium and circular cowling 50, to dry After the completion of roasting, circular cowling 50 is dismantled in the case of the insulating layer formed after not influencing to bakee at notch perisporium.Circular cowling 50 Opposite side side wall (the present embodiment, that is, madial wall) can be with the directly fixed sealing-in of the rack 101 in the middle part of armature.

In addition, the sealing between circular cowling 50 and notch perisporium, can also be realized by way of hermetic seal.Such as figure Shown in 32, the annular sidewall that circular cowling 50 corresponds to notch perisporium can be set to hollow sidewall, moreover, hollow sidewall is close to winding One end of groove 100b is equipped with out compression ring 501a, goes out compression ring 501a and is equipped with gas outlet, side direction of the gas outlet from ferromagnetic parts 100 The port position of slot for winding 100b.Source of the gas is also supplied to hollow sidewall, so that gas can be discharged through gas outlet.It is although hollow Side wall and go out between compression ring 501a and notch perisporium there are radial clearance, but go out compression ring 501a from side to ferromagnetic parts 100 Notch perisporium jet, gas in circular cowling 50 can be prevented to be overflowed from gap location, sealed with gas common implementing in circular cowling 50 It is stifled, prevent the steeping liq of slot for winding 100b ends from overflowing axially, radially, and hermetic seal does not interfere with slot for winding 100b ends Insulating layer after the steeping liq baked and cured of portion position is formed.

Going out compression ring 501a one or can be separately set in hollow sidewall, Tu34Zhong, and it is independent component to go out compression ring 501a, Split is arranged on hollow sidewall.It is appreciated that hollow sidewall directly processes above-mentioned gas outlet close to the end of slot for winding 100b And it is feasible, hollow sidewall is integrally provided on equivalent to compression ring 501a is gone out, certainly, it is easy to process to be separately provided out compression ring 501a, Also allow for being selected differently from 501 scratch-resistant material.

Please continue to refer to Figure 32, sealing gland portion 30 has end plate 301, and the sealing gland portion 30 of above example description includes pressure accumulation Chamber 33, pressure accumulation element 32 and confluence chamber 31, end plate 301 are to seal pressure accumulation chamber 33, pressure accumulation element 32, the end for the chamber 31 that converges Plate (specifically in arced strip, or for sector), to ensure gas in each inside cavity, to slot for winding 100b jets.Armature is drying Rotary state is in roasting technique, and sealing gland portion 30 is then opposing stationary, at this time, in order to avoid end plate 301 and ferromagnetic parts 100 Notch perisporium frictional interference, end plate 301 and notch perisporium can also take hermetic seal.

As shown in figure 32, end plate 301 (is in the present embodiment specifically the interior of end plate 301 close to the perisporium of slot for winding 100b Perisporium) towards compression ring 501a settings are gone out, go out compression ring 501a and be additionally provided with gas outlet towards the perisporium.Arrow shown in Figure 32 It can be seen that, gas is going out in compression ring 501a, while prevents gas overflowing in circular cowling 50, side to both sides jet, side jet Jet prevents pressure accumulation chamber 33, pressure accumulation element 32, the gas in confluence chamber 31 from overflowing vertically.

In order to strengthen sealing, end plate 301 can also be equipped with sealing tooth 301a close to the perisporium of slot for winding 100b, seal tooth 301a can extend the flow path of gas, there is provided resistance, prevents the gas in sealing gland portion 30 from overflowing from there.

Further, in end plate 301 and can also go out to set feeler 70 between compression ring 501a, to detect between the two Whether away from predetermined minimum zone, avoiding based on the reason such as installation error, end plate 301 is contacted with going out compression ring 501a and revolved Turn to produce excessive friction in baking process.

It should be noted that in above example, armature is illustrated by taking the inner stator of motor, outer-rotor structure as an example, Slot for winding 100b is arranged on the periphery of stator ferromagnetic parts 100, in fact, slot for winding 100b is arranged at the interior of ferromagnetic parts 100 In week, use as external stator, also possible, at this time, sealing gland portion 30 and other every building blocks in above-described embodiment It can be applicable in, accommodation is made in direction position.

5-37 is please referred to Fig.3, Figure 35 is the structure diagram of another embodiment of armature provided by the present invention；Figure 36 is this hair The structure diagram of another embodiment of rotary roasting device of bright provided armature；Figure 37 is that jet prevents maceration extract in Figure 35 The schematic diagram that body overflows.

As shown in figure 35, which sets the slot for winding 100b of winding 200 around the home in its inner circumferential, in this way, In rotary course, when slot for winding 100b is rotated to top, its slot for winding 100b notches can downward, and steeping liq equally exists easily In overflow the problem of.As shown in figure 35, unlike the embodiments above, sealing gland portion 30 is not outside the bottom of ferromagnetic parts 100 Side, and it is provided at the space at the middle part of ferromagnetic parts 100.At this time, confluence chamber 31, pressure accumulation element still are set gradually along jet direction 32nd, pressure accumulation chamber 33, to the inner peripheral wall 100c jets of ferromagnetic parts 100, slot for winding 100b is arranged on inner peripheral wall 100c.Therefore with Unlike above-described embodiment, Figure 14 embodiment jets direction is that radially-inwardly, and the embodiment is due to being then after oppositely arranged Radially outward jet.But the principle that jet suppresses steeping liq spilling is identical, and details are not described herein again.

Correspondingly, above-mentioned circular cowling 50 is being set, is carrying out sealing, the gas of 100 notch perisporium of circular cowling 50 and ferromagnetic parts During the sealing of 100 notch perisporium of 30 annular endplate 301 of envelope portion and ferromagnetic parts, setting direction is contrary.At this time, notch perisporium is The internal perisporium of ferromagnetic parts 100, the annular sidewall of circular cowling 50 corresponding with notch perisporium is its madial wall, with notch perisporium pair The annular perisporium for the annular endplate 301 answered is its periphery wall.The structure all sames such as compression ring 501a, sealing tooth 301a are set out, no Repeat.

In addition, gas reclaiming chamber 10 can be still set in the way of above-described embodiment.Certainly, the setting in source 20 is bakeed Mode can be different, that is, bakeing source 20 can not be located in gas reclaiming chamber 10, but still be located at the top of armature.

As it can be seen that how the present embodiment prevents slot for winding 100b and slot wedge 300 at the slit aperture of port position if also detailed is Steeping liq overflows.

To sum up, on the basis of the ferromagnetic border structure of traditional armature, the present embodiment is in ferromagnetic border 100aL and groove Between wedge 300, and the above two are revolved between the exposed handover region with air of slot wedge side three of bottom insulation 200f in tradition Turn to construct sealing protection system during baking process, overcome insulated paint by gravity and the multiple synergy of centrifugal force；Separately ward off footpath Footpath, by the variable section channel theoretical direction of the engineering fluid mechanics of In Engineering Thermal Physics so that the traditional iron of machine winding Magnetic border new construction has the dual-use function that the radial direction that a dipping lacquer is prevented after vacuum pressure impregnation is lost in, is axially lost in.This The it is proposed of item innovation is follow-up to technique of vacuum pressure for dipping electrical and can reduce drop paint process, rotary roasting process insulated paint edge after dipping lacquer The radial flow on traditional ferromagnetic border is become estranged the axial loss on ferromagnetic border, is improved the full of insulated paint filling dipping after dipping lacquer Full rate, and take the lead in having blocked the slit aperture that insulated paint is lost in naturally in process, increase border prevents moisture and other media from invading The ability entered.Make the oxygen in air, moisture and water etc. be not easy to invade inside slot insulation, insulation system ageing process can be delayed.Drop Low motor is immersed by moisture and water retains risk therein, improves insulating reliability, and pinned the loading of insulated paint.

For the various embodiments described above, vision system can also be further set.8-40 is please referred to Fig.3, Figure 38 is the present invention Maceration extract in embodiment at vision system monitoring armature diverse location between ferromagnetic parts 100 and slot wedge 300 around slit aperture The schematic diagram for the gas-liquid interface that body is formed with peripheral gas；Figure 39 is the composition schematic block diagram of vision system in Figure 38；Figure 40 is Image of (4 thirty) direction in three different times 4.5 points in Figure 38.

The vision system includes optical imaging device 80, and optical imaging device 80 includes lighting system (light as depicted Source 801), visual sensor 802, image pick-up card, camera control unit 5, computer system, light source controller, wherein, calculate Machine system includes I/O interfaces, host, display, image processing software, communication interface, each composition portion of optical imaging device 80 Divide and operation principle is the prior art.

It has the function of to analyze and process vision signal.

As described above, optical imaging device 80 is used to obtain at slot for winding 100b gas-liquid circle around gas-liquid interface or slit aperture The image information in face, becomes apparent since the steeping liq in notch slot for winding 100b just directed downwardly overflows, has certain generation Table, so being preferably able to monitor the position of notch slot for winding 100b just directed downwardly during monitoring.As shown in figure 36, one group of optics Imaging device 80 is arranged at 301 position of end plate in sealing gland portion 30.

Gas-liquid interface in Figure 38 between the specific slot for winding 100b and slot wedge 300 obtained at three positions around slit aperture Image information.Figure 38 with when hour number marker location information, i.e., 12 points (surface, slot for winding 100b are upward), 3 points, 4.5 points (i.e. 4 thirty), 6 points (underface, slot for winding 100b are downward), 9 points of totally six positions, monitor, 7.5 (i.e. 7 thirty) at 4.5 points at 6 points The image information of slot for winding 100b at point three at position.From image information, corresponding slot for winding 100b and slot wedge 300 can be obtained Between gas-liquid interface around slit aperture state, that is, analyze characteristic quantity of the steeping liq in the position, be, for example, maceration extract The shape of body overflow, position of flow fronts etc., obtain the variation tendency of steeping liq overflow shape, the position of flow fronts becomes Change trace.

Using the armature periphery wall at slot for winding 100b and slot wedge 300 as foundation, in the image information of acquisition, Main Analysis is high In the overflowing liquid Q on foundation surface, maximum cross section, gas-liquid interface be (i.e. in the axial direction：The contact surface of steeping liq and air-flow) face Product and area variation tendency.

As shown in figure 38, three groups of crescent structures are shown respectively on the outside of three positions of monitoring, that is, the image letter shot The image of the overflowing liquid Q reflected in breath, is labeled with (1), (2), (3) at crescent structure, embodies according to time order and function institute The thickness change image that the steeping liq of acquisition overflows, wherein (1) is the image information shot at first, (2), (3) sequentially obtain. As can be seen that in the case of not interfered in sealing gland portion 30 or air pressure to the active force of slit aperture be not enough to prevent overflow feelings Under condition, over time, the amount that steeping liq overflows gradually increases, and can also understand with reference to figure 40, Figure 40 is same position The image of gas-liquid interface at the slot for winding 100b of place's different time shooting is put, the direction of arrow is moved towards for the time, and left side is newest Image.

Rotary roasting device further comprises controller 5, and vision system output image information to controller 5 can be direct Image information without analysis is sent to controller 5, is analyzed by controller 5 or the computer of vision system Image information is fed back into controller 5 after network analysis.Controller 5 carries out the control of rotary roasting according to image information, Particular by the control rotating driver e controls rotary speed of armature, supply gas pressure, the feed air temperature in above-mentioned sealing gland portion 30, Here the adjustment of feed air temperature can influence Baking Effect, because feed air temperature adjusts the viscous of rotary roasting process steeping liq Degree.

By above-mentioned analysis, steeping liq is in rotary course, due to the addition in sealing gland portion 30, its degree overflowed It can be influenced be subject to the gas pressure that the viscosity, rotating speed, sealing gland portion 30 of steeping liq provide.

In Figure 38, optical imaging device 80 is except just slot for winding 100b positions (6 positions), also acquisition circumferential direction go up other downward The image information of diverse location, mainly have chosen the slot for winding 100b of a few place's exemplary positions (3 points, 4.5 points, 7.5 points, 9 points) with Gas-liquid interface image information between slot wedge 300 at slit aperture.When controller 5 can obtain the figure at multiple circumferential diverse locations During as information, then it can know that liquid of the same slot for winding 100b at diverse location overflows characteristic quantity, and may determine that liquid Whether spilling is controlled, and preferably removes control rotary roasting.

For example, according to the analysis of image information, when overflowing liquid Q maximum cross section, the gas-liquid in the axial direction on foundation surface When interfacial area persistently increases, then the control of controller 5 improves supply gas pressure, improves armature rotating speed (mainly in steeping liq curing Use at initial stage), until higher than foundation surface and untill maximum cross-section, gas-liquid interface area no longer increase in the axial direction.

Wherein, above-mentioned supply gas pressure can be the pressure in pressure accumulation chamber 33, in pressure accumulation chamber 31 pressure can be set to pass Sensor detects the pressure.When carrying out supply gas pressure adjustment, pressure sensor, flow sensing transmitter 44 can measure instead Feedback, real-time tracking.
