Definitions
- the present invention shows a system and a method that make it possible to impregnate components, in particular stators and rotors of electrical machines, quickly, efficiently and with complete slot filling using the roller dipping method, without wetting the outer and/or inner diameter of the laminated core .
- the impregnating agent is applied and/or introduced during the rotation of the stators and rotors, hereinafter referred to as components.
- the components are placed in the dipped in impregnating agent. The immersion takes place either until the impregnating agent has gelled in the area of the heated winding or by building up layers through repeated immersion, gelling and intermediate heating.
- Dipping has the advantage of good groove filling and is known as a quick impregnation process. Disadvantages of this method are the contamination of the entire component due to the adhesion of impregnating agent and the associated loss of dimensional accuracy, the increased consumption of impregnating agent and the environmental pollution caused by the impregnating agent being discharged, and the necessary recooling of the impregnating agent.
- the impregnating agent When the impregnating agent is applied with rotation, i.e. trickling, contamination of the laminated core is generally avoided, the consumption of the impregnating agent is kept to a minimum and the environmental impact is also greatly reduced.
- the problem is the duration of the impregnation process, the associated long gelling time and the inadequate filling, particularly of long laminated core grooves, in this process.
- Stators of electrical machines usually consist of a ring-shaped laminated core with grooves running on the inside diameter, into which the winding is inserted.
- the end windings which serve to deflect the copper wires between the slots or to connect them, protrude over the flat surfaces of the laminated core.
- the winding wires are currently being replaced more and more by copper rods or flat wires.
- the rotor later runs in the central bore of the ring-shaped stator. In conventional roller dipping systems, the inside diameter of the stator is held by a clamping device.
- the slowly rotating stator is then immersed in a tub filled with a defined level of impregnation agent.
- the level is usually determined by overflow elements, in that more impregnation agent is always fed in than is removed by the component.
- the stator With roller dipping, the stator is only dipped into the impregnating agent bath to such an extent that the inner diameter remains unwetted and therefore not contaminated. This also applies to the rotor if the rotor shaft has not yet been installed. If it is already installed, only immerse so far that the shaft does not come into contact with the impregnating agent.
- the disadvantage is that the outer diameter of the laminated core is wetted and contaminated with impregnating agent.
- the winding and the plane sides of the laminated core slots are only partially immersed compared to immersion, which leads to longer impregnation times and less well-filled laminated core slots. Because the impregnating agent flows simultaneously into the grooves from both flat sides of the sheet metal package while the component is rotating horizontally in the impregnating agent bath, the enclosed air prevents the filling of the grooves in the middle area.
- the resin on the outer diameter of the laminated core is stripped and/or blown off as far as possible before it hardens in the subsequent gelling and hardening process.
- the roller dipping process Due to the fact that there can only be one medium in the immersion tub, the roller dipping process has the condition that the impregnating agent is already reactive material, which is usually activated by temperature.
- the published application DE 36 31 980 A1 presents a method for impregnating the windings of electrical machines, in which the electrical machine parts are trickled while rotating in the longitudinal axis directed at an angle to the horizontal and then partially immersed in a resin immersion bath in a horizontal position for roller immersion, with the winding heads also being sprinkled will.
- the outer skin of the laminated core is thereby contaminated with resin.
- JP H10-271 775 A presents an impregnation method for rotors of electrical machines, in which the impregnating agent is sprinkled on at different inclined positions of the rotating rotor in order to achieve better entry into the grooves traversed by windings.
- Document JP H08-317616A presents a method and a device for roller dip impregnation of the slots in laminated cores for stators. This means that the slot insulation that is usually used in the laminated core can be replaced. In order for the air to be able to escape from the grooves more easily, the laminated core is introduced into the impregnation bath at an angle. The laminated core is covered with resin both inside and outside contaminated. In addition, no level difference along the stator is shown.
- EP 0 321 223 A2 shows a system in which the rotor slots are also insulated by means of roller dipping before the copper windings are drawn in.
- the immersion tank with the insulation medium is in a horizontal position.
- JP 2005-285 933 A presents an immersion process in which components with windings are placed in an immersion bath subjected to ultrasound in order to fill the cavities between the winding and the laminated core faster and better with resin.
- the outer skin of the laminated core is contaminated with the impregnating agent.
- WO2019/21 1461 A1 presents a method in which the impregnating agent is introduced into the laminated core grooves by means of a carrier medium. This method is currently still very expensive and, given the small spaces between the flat wire windings and, in particular, the hairpin stators, it has been difficult or impossible to implement so far.
- the stators with a central axial hole for the rotor are dipped into horizontally positioned roller dipping tanks with an impregnating agent bath to such an extent that the resin can enter the grooves of the laminated core and enclose the winding parts and the resin level does not reach or wet the inner diameter of the stator.
- the inner diameter of the laminated core is also contaminated with resin.
- the stator rotates slowly in the resin bath. Not only is the winding impregnated with resin, but the outer diameter and the flat surfaces of the laminated core are also contaminated with resin.
- the resin on the laminated core is usually disadvantageous because it causes problems when shrinking into the housing or when sealing the stator due to a lack of strength and dimensional accuracy.
- the resin adhering to the outer skin of the laminated core is removed by scraping and/or blowing off, as far as this is subsequently possible. This brings additional operations and significantly increases the emission of resin fumes.
- the new solution is therefore based on the task of proposing a system and a procedure that, when impregnating round wire and flat wire windings on electrical machines, enables complete slot filling, short cycle times and a clean laminated core, as well as minimal consumption of impregnating agent.
- the presented sector roller dip system is a new design of a roller dip system, in particular for introducing impregnating agents such as resins into the cavities between the laminated core grooves and the winding and between the windings on the end windings. Impregnation is used for additional insulation, better heat transfer and mechanical fixation of the copper parts called the winding.
- the special features of the sector roller dip system are the dip tank divided into sectors and the sealing elements installed between the component and the dip tank or the bulkheads. The bulkheads delimit or define the sectors within the rolling immersion tank.
- the sealing elements contribute to the fact that the resin level in the individual sectors only rests up to the points on the component where the sealing elements connected to the bulkheads rest.
- roller dip tank divided into sectors allows different resin levels in the different sectors. They also allow impregnant-filled and empty areas of a roller dip tank to be next to one another. It is also possible for the first time to tilt a roller dip tank filled with a liquid medium and thereby generate different fluid levels within a roller dip tank.
- the sector roller dipping system is characterized by the fact that, for the first time, inclined components can be roller dipped and, in addition, lateral surfaces with the largest outer diameter can remain free of impregnating agent, both in the case of inclined and horizontal component positions.
- gravity can be used in addition to the capillary effect to fill the laminated core slots through which the winding runs.
- the sector roller dip system features a roller dip tank that is divided into sectors in order to implement different impregnation agent levels depending on the component region. This makes it possible, for example, to turn the end windings of a stator in the impregnating agent bath without wetting and soiling the outer skin of the laminated core that has a larger or the same diameter.
- the bulkheads between the sectors of the immersion trough preferably point towards the component in the contact area sealing elements.
- the bulkheads themselves are designed as a flexible sealing element, which optionally already has the contour of the component at the point to be sealed, or adapts to this contour.
- the roller dipping tank of the system presented is either connected to the swivel unit of the component transport unit and is tilted together with the component, or it has a separate drive that allows independent or synchronous tilt angles and linear movements to be carried out in relation to the component.
- the bulkheads in the rolling immersion tank are fixed or can be moved manually and/or by motor.
- the sectors can thus be adapted to different components and, if necessary, the bulkheads with the sealing elements can be moved against the sealing surfaces of components and pressed to different degrees. Both the bulkheads and the sealing elements are interchangeable.
- An immersion tub designed for inclined use preferably has at least one reservoir for the impregnating agent.
- this impregnating agent reservoir has the function of emptying itself at least far enough for the sector to be filled with impregnating agent to reach the desired level.
- the impregnating agent reservoir fulfills the task of receiving the impregnating agent from the impregnating sector or temporarily storing it until it is needed again.
- Impregnation agent which flows over a bulkhead that is not provided with a sealing element and thus defines the level, reaches separate impregnation agent reservoirs or buffers and is fed to the next component.
- the bulkheads serve to keep the impregnating agent away from the areas of the component that are not to be impregnated and thus to noticeably reduce the consumption of the impregnating agent, to prevent the heat dissipation by the impregnating agent at these points and to avoid contamination of the components at these dimensionally sensitive points.
- the bulkheads are therefore provided with sealing elements that can be adapted in particular to the component contour.
- the bulkheads themselves are designed as flexible sealing elements, e.g. B. made of rubber. It is advisable to adapt this to the component contour.
- the impregnating agent remains in the impregnating sector with the last impregnating agent therein.
- the impregnating agent level rises while the sealing elements sink as they nestle against the contour of the component.
- the maximum level is defined by height-adjustable bulkheads.
- impregnating agent is fed in as is removed by the component or as is to be removed. To a small extent, this method allows for a component-specific quantity equalization of the impregnating agent.
- the mass of impregnating agent removed is preferably additionally determined by weighing the component before and after impregnation.
- the impregnating agent is at least partially fed back into an impregnating agent reservoir or an intermediate store before the component is removed from the trough to prevent the overflow of the impregnating agent avoided by means of the sealing element contour.
- the impregnating agent is returned to the immersion sector.
- the impregnation preferably only the amount of impregnating agent currently removed by the component is then fed in. This makes it possible for the first time to implement a roller dip impregnation solution without an overflow.
- reservoirs are used, if possible in the form of hydraulically connected cylinders, to temporarily collect the impregnation agent from the individual sectors.
- the cylinder sucks off the impregnating agent at least for the most part via the bottom opening before the component is removed and, after the new component has been positioned, conveys it to the corresponding one Sector of the roll-over tank closes quickly. The quantities and therefore the level remain the same. Only the amount of impregnating agent that is or may be removed from the component at the respective sector at the relevant time is then conveyed.
- a roller dip tank that is close to the contour of the component allows the quantity of impregnating agent stored in the respective segment to be significantly reduced, so that the impregnating agent, once it has been fed in and heated, only remains in the roller dip tank for a short time.
- the large proportion of freshly supplied cool impregnating agent helps on the one hand and a cooled roller dip tank and possibly cooled impregnating agent-receiving cylinders on the other.
- the sector roller immersion system is optionally equipped with a vacuum chamber, which allows impregnation with the exclusion of air to a large extent.
- the vacuum chamber encloses either only the component with the roller dipping tank or the entire roller dipping station.
- the impregnating agent is prepared under vacuum before use, i.e. degassed and dehumidified.
- a vacuum-tight impregnating agent reservoir is provided for the impregnating agent so that the impregnating agent does not come into contact with the moist ambient air when removing and inserting the component. The impregnating agent is then brought into the impregnating agent reservoir before aeration and pushed back into the immersion sector after vacuuming.
- a cylinder is preferably used as the impregnating agent reservoir.
- the immersion tank is designed as the lower part of a horizontally divided vacuum chamber. Only the component carrier to be sealed protrudes into the vacuum chamber, the shaft of which is surrounded by the two chamber halves.
- the vertical axis of the immersion tank or the lower half of the vacuum chamber is used at the same time to open the chamber and to Adjusting the immersion depth for the component in the impregnating agent.
- vibrations in particular high-frequency vibrations in the ultrasonic range, which act on the impregnating agent and/or the component, the degree of filling and the wetting of the cavities around the winding are improved, which further reduces the impregnation time.
- frequencies from 20 Hz to 20 MHz are used for this.
- Figure 1 shows an example of a swiveling sector roll diving system in the side view
- FIG. 2 shows a slanted roller dip tank 6 in section with component 1 in a side view in an inclined impregnation position.
- FIG. 3 shows the roller dip trough 6 in section with component 1 in a side view when component 1 and impregnating agent 12 are being introduced and removed in the impregnating agent reservoir 9 and
- FIG. 4 shows the exemplary embodiment of a rolling immersion tub 6 with sectors for different functions in a plan view.
- the sector roller dip system is used for roller dip impregnation of the windings 2 of components 1 of electrical machines, in particular stators and rotors.
- the component 1 rotates during the impregnation process carried by a component carrier 5 in a program-predefined position of the sector roller immersion system and in particular the roller immersion tank 6.
- the position-fixed rotary drive of the component 1 about the axis of rotation 17 is realized by pairs of chains running in opposite directions in the transport device 19, which act on the sprockets firmly fixed on the component carrier 5.
- the rolling immersion tank 6 of the system presented is either connected to the swivel unit of the transport device 19 fixed on the swivel axis 16 and is tilted together with the component 1, or it has a separate drive that allows the tilt angle of the component 1 to be followed independently or synchronously and to perform linear movements relative to the component 1 by means of at least one linear axis 15 .
- the linear axes 15, the pivot axis 16 and the translational and rotational movement of the component 1 about the axis of rotation 17 are driven by the actuators 18.
- the bulkheads 7 in the rolling immersion tub 6 are positioned in a fixed manner, depending on the requirement, or are mounted so that they can be moved manually and/or by motor. The sectors can thus be adapted to different components 1 and, if necessary, the bulkheads 7 with the sealing elements 8 can be moved against the sealing surfaces of components 1 and pressed to different degrees. Both the bulkheads 7 and the sealing elements 8 are interchangeable.
- the component carrier 5 has an integrated clamping device that enables different components 1 to be fixed centrally relative to the component carrier 5 .
- the component carrier 5 with the integrated clamping device allows the components 1 to be replaced at predefined points and the rotating components 1 to be transported safely through the entire system.
- the translatory movement of the component 1 with simultaneous rotation is effected by different speeds and/or directions of movement of the chains of the transport device 19 driven via shafts and sprockets.
- the component 1, in particular the stator consists essentially of a laminated core and the winding 2, which can also consist of round wires or flat wires or hairpins.
- the winding 2 is located in the stator in the inner laminated core slots 4.
- the deflection and connection of the wires or hairpins referred to as the winding 2 outside of the laminated core are referred to as the end windings 3.
- the roller dip trough 6 is specially shaped.
- this project is achieved by bulkheads 7, which are located in the rolling immersion tank 6 and are equipped with sealing elements 8, or are at least partially made up of sealing elements 8.
- the bulkheads 7 are preferably made of elastomers, which adapt to the contour of the component 1 and at the same time act as a sealing element 8 .
- This roller dip tank design makes it possible to realize different impregnation agent levels in adjacent sectors of the roller dip tank 6 and thus to determine which parts of a component 1 come into contact with the impregnation agent 12 .
- the sector in which the laminated core that is not to be impregnated is located remains empty.
- the impregnating agent 12 can only reach the end windings 3 and the laminated core slots 4 if the stator is immersed to a maximum of the lower edge of the inner diameter.
- the end windings 3 and the slots 4 of the laminated core are filled all round by slow rotation, while the core remains clean on the inside and outside diameter.
- sealing takes place on the planar surfaces, so that the impregnating agent 12 can only enter and exit at the planar surfaces and only the ring surfaces on the planar sides are wetted.
- FIG. 2 shows an example of a roller dip tank 6 with bulkheads 7 and sealing elements 8 attached thereto for roller dip impregnation in an inclined position in section, while the stator stretched on the component carrier 5 can be seen uncut in the side view in the impregnation position.
- the sectors divided by the bulkheads 7 can be seen.
- the individual sectors are provided with impregnating agent inlets 11, which are used both for the inflow and for the outflow of the impregnating agent 12.
- Part of the bulkheads 7 is without a sealing element 8 and is therefore lower than the bulkheads 7 with integrated or attached sealing elements 8. They serve as an impregnating agent overflow 10 and thus limit the level. This means that an even level of impregnation agent and thus a reliable immersion depth can be achieved quickly and with repeatability.
- the overflowing impregnating agent 12 is either returned to the original sector by pivoting the rolling immersion tub 6 or is collected in a separate sector and given priority to the impregnating agent feed.
- the higher immersion sector 13 of the roller dip trough 6 also functions as an impregnating agent reservoir 9 as soon as the roller dip trough 6 is brought into a horizontal position.
- the impregnating agent 12 flows back into the lower-lying area, causing the impregnating agent level in the area of the component 1 to drop below the lowest point of the sealing element 8 or the bulkhead 7.
- no impregnating agent 12 flows over the sealing element 8; the previously existing level is reached immediately when the new component 1 is swiveled in, without the impregnating agent 12 being fed in and removed.
- the impregnating agent 12 is supplied and optionally also removed via the impregnating agent inlets 11 .
- the level of the impregnating agent 12 is also limited by impregnating agent overflows 10 . Overflowing impregnating agent 12 is caught in overflow sectors 14, as can be seen in FIG. 3, and diverted if necessary. This ensures on the one hand that the level of impregnation agent does not rise above the lower edge of the inner diameter and thus soil the interior of the stator and on the other hand that the sector in which the laminated core is located remains free of impregnation agent 12 .
- the immersion depth of the component 1 in the impregnating agent 12 is defined by the freely programmable position of the component 1 in relation to the roller immersion trough 6 .
- the roller immersion tank design shown in FIG. 2 is designed with bulkheads 7 and sealing elements 8 in the immersion area, which are adapted to the contour of the component.
- the round sealing elements 8 shown are preferably designed as sealing lips, so that no residue of impregnating agent 12 flows over when the component 1 is lifted. Due to the axial mobility of the roller dip tank 6 and a roller dip tank inclination that is independent of the component inclination, the insertion of the component 1 between the seals can also be managed when the bulkheads 7 and the sealing elements 8 attached to them are not movably mounted in the roller dip tank 6.
- an inclined component 1, in particular a stator can also be implemented in the proposed manner with only one sealing element 8, in that not only the laminated core grooves 4 with the winding 2 located therein from the upper immersion sector 13, but also the opposite end winding 3 through the Blechpaktnuten is impregnated through.
- the lower immersion sector 13 can also be over
- Impregnating agent inlets 1 1 fill with impregnating agent 12 with what at the same time the dip impregnation of the lower winding head 3 is possible.
- impregnating agent reservoir 9 which is also immersion sector 13 at the same time, can be seen from FIG. In the horizontal position, the level of the impregnating agent 12 drops so far that no impregnating agent 12 flows out via the sealing element 8 when the component 1 is removed.
- the roll immersion tub 6 shown as an example in FIG. 4 includes bulkheads 7 which seal against the tub and are mounted in different positions depending on the component dimensions.
- the bulkheads 7 are interchangeable, so their fleas and shapes can vary. In an optionally proposed version, they are mounted so that they can be moved continuously and can be positioned manually or automatically using linear drives.
- the maximum height of the impregnating agent in the tub is defined by the height of the bulkhead 7 itself or by height-adjustable sliding elements. These sliding elements, or if they are not present, the bulkheads 7 without sealing element 8 optionally serve as impregnating agent overflow 10.
- the overflowing impregnating agent 12 is preferably collected in overflow sectors 14 and fed to the impregnating agent inlet.
- the central area of the bulkheads 7 is designed as an arc to match the component contour at the point to be sealed.
- the sealing elements 8 run along the curved contour and are connected to the bulkhead 7 in a sealing but interchangeable manner.
- the ends of the sealing elements 8 made of polymers or metals are shaped outwards in order to catch impregnating agent 12 that occasionally runs outwards on the planar surface.
