Definitions
- the invention relates to a cover slide, a stator, a dynamoelectric machine and a method for impregnating a stator of a dynamoelectric machine.
- Dynamoelectric machines have a winding system in their grooves, which generates a magnetic field when energized and causes movement due to electromagnetic interaction with the corresponding machine parts.
- the winding system in the slots and/or the end windings is filled or provided with insulating resin and then hardened.
- This impregnation serves to fill cavities in the dielectric and in the heat flow paths. This avoids glow discharges and reduces thermal resistance.
- the impregnation serves to strengthen mechanically.
- impregnation with liquid reactive resin and subsequent curing is also a very time-consuming and costly process compared to the other production steps, such as winding , retraction, phase separation.
- These are often large immersion impregnation stations.
- the impregnation process itself is an integral process, with many axis heights and sizes going through an immersion and/or temperature profile. This makes it almost impossible to obtain an individual optimization of the impregnation parameters for one engine type.
- trickling process is known as an impregnation method for very defined impregnation processes, whereby the liquid resin is applied to the rolling stator by high-precision dosing systems.
- Preheating the Sta tor produces a viscosity reduction of the resin, which the onset of the capillary effect is promoted and the stator slot gradually fills with resin.
- the trickling jet of a trickling system hits a wide variety of substrates, which all have to guarantee this minimum absorption capacity in order to ultimately ensure sufficient operational reliability of the dynamo-electric machines .
- different types and quantities of surface insulating materials can represent barriers within the slot, which prevent the resin from optimally flowing into the winding.
- These surface insulating materials e.g. Nomex papers, multilaminates made from PET film and aramid fabric
- Inadequate flow behavior in the groove can be conventionally reduced by adjusting the resin.
- the resin chemistry can be adjusted in such a way that it is a more liquid material, which may also have a delayed gel point, so that the material can flow more quickly around flow barriers and long slot bars.
- the object of the invention is to improve the impregnation under the parameters mentioned above and to provide a stator and a dynamoelectric machine with reliable impregnation.
- the solution of the task is achieved by a deck slide of a dynamoelectric machine, with a first layer and a second layer, which are at least partially spaced from each other, so that a channel is formed in between.
- the solution to the problem is also achieved by a stator with a hollow-cylindrical, magnetically conductive body, which has on its inner or outer lateral surface essentially axially running, partially open slots, in which a winding system is arranged, which are closed by a cover slide according to the invention.
- the object is also achieved by a method for manufacturing/impregnating a stator with a hollow-cylindrical, magnetically conductive body, which has partially open grooves running essentially axially on its inner or outer lateral surface, in which a winding system is arranged, by the following Steps:
- a cover slide is now designed with two layers.
- the cover slide has two layers spaced apart from one another, which form a flow channel so that the resin can reach its respective destination in the groove without barriers.
- a surface insulating material is considered as the cover slide, which is formed as a strip, particularly in the case of trickle windings, and positions the winding in the slots.
- slot box serves as the slot lining. Included It is a folded surface insulating material whose cross-sectional shape is ideally adapted to the contour of the slot and lies against the slot wall.
- the slot lining forms an additional flat electrical barrier between the winding system, in particular the copper winding designed as enameled wire, and a magnetically conductive body, such as a laminated core.
- the slot is closed with a cover slide according to the invention, which also consists of a folded surface insulating material and has so far had two important functions. On the one hand, this creates the necessary air and creepage distances, since the cover slide and groove box overlap at the edges.
- the slot box wedges itself with the slot tooth and thus mechanically fixes the winding in the slot so that no individual wires can slip back through the slot slot into the area of the air gap or the rotor.
- the cover slide forms a main channel which is filled with reactive resin during the impregnation process and contains the copper winding.
- One or more efficient flow channels for inflowing resins are formed via the cover slide according to the invention, which at least viewed axially, is designed in two layers to flow into the center of the groove and to be distributed there.
- the flow tubes are formed by corrugating one layer and/or there are perforations in one layer—the layer facing the winding system—which ensure or at least support a predeterminable distribution of the resin within the axial length of the groove.
- a kind of flow channel is created by a double layer of the cover slide, which has its openings at the axial groove exit.
- the inner layer of the cover slide can be perforated, ie see ver with exit holes or be divided into two, with a non-flush butt joint in the middle of the sheet.
- the cover slide itself could be "corrugated" on one side in the longitudinal or axial direction, so that a flow tube that is as defined as possible is created, in particular towards the center of the groove.
- a second layer of the cover slide that protrudes further axially outwards, optionally with a slight fold, enables the resin to be better absorbed when dripping onto the inner radius of the groove exit. Thus, an improved inflow into the "flow channel" is again guaranteed.
- Both the inner and the outer layer could be used with ribs in order to use logistical synergies for the manual workstations, among other things. This would only require material sold by the meter.
- the corrugation affects the flow behavior of the resins only to a small extent, but has a positive effect on the mechanical strengthening of the copper wires and can prevent wire crossings, at least in the innermost winding layers.
- the winding system is filled or covered with insulating resin in the slots and/or the end windings and then hardened.
- the impregnation serves to fill cavities in the dielectric and in the heat flow paths. This avoids glow discharges and reduces thermal resistance.
- the impregnation serves to strengthen the material mechanically.
- the cover slide according to the invention reduces the impregnation times of the stator and also creates a high-quality impregnation of the stator and thus of a dynamo-electric machine that can ensure reliable operation of the dynamo-electric machine.
- FIG2 shows a cross section of a groove
- FIG. 1 shows a longitudinal section of a dynamoelectric machine 1 shown in principle, with a stator 2 which has axially running slots 3 in which a winding system 5 is arranged. Across an air gap 20, the energized stator 2 enters into magnetic interaction with a rotor 17, which causes the shaft 18 to rotate about an axis 19.
- the dynamoelectric machine 1 is surrounded by a housing 22 which is supported on the shaft 18 via bearings 21 .
- slot lining is a folded flat insulating material which, with its cross-sectional shape, is ideally adapted to the contour of the slot and rests against the slot wall.
- the slot lining or slot insulation 4 forms an additional flat electrical barrier between the winding system 5, in particular a copper winding designed as enamelled wire, and a magnetically conductive body, for example a laminated core.
- the trickling process is used, among other things, whereby the liquid resin is applied to the rolling stator 2 using high-precision dosing systems.
- Preheating the stator 2 reduces the viscosity of the resin, which promotes the onset of the capillary effect and fills the slot 3 of the stator 2 gradually with resin.
- FIG 2 shows a cross section of a groove 3 of the dynamoelek tric machine 1, which has a winding system 5, which is formed from round wires.
- a winding system 5 which is formed from round wires.
- the inside of the slot 3 is provided with slot insulation 4 .
- a cover slide 9 according to the invention, with a first layer 7 and a second layer 8 covers the groove 3 direction air gap 20 from Rich.
- the first layer 7 is arranged directly on the groove slot and points there to the air gap 20 of the dy namoelectric machine 1.
- the second layer 8 is spaced radially from the first layer 7 and thus forms an axia len channel.
- An overlap is formed with the slot insulation 4 in such a way that the cover slide 9 is arranged within the slot insulation 4 at least in sections.
- FIG. 3 shows the basic resin flow 12 in a cover slide 9 according to the invention during pouring.
- the winding system is supplied with resin axially from both sides.
- resin is also brought into the "critical" areas of the winding system via the flow channels 13 of the cover slide 9. This is particularly important when using a 2- component liquid resin advantageous, which have a relatively fast gel time Even at low temperatures, the viscosity limit is not exceeded so quickly and thus the flow range is increased.
- the cover slide 9 has an axially continuous first layer 7 but an interrupted second layer 8 . Resin can now flow through this gap in the second layer 8, especially in the middle area. The second layers 8 therefore do not collide flush.
- the cover slide 9 according to the invention thus enables a comparatively better or optimal filling, in particular of the middle of the slot 3. Without this cover slide 9, the resin would first have to pass through the complete winding system 5, in particular the complete copper winding up to the middle of the slot 3 and must not run too early gel. If the resin gels prematurely, the center of the groove 3 is not filled with resin.
- the resin is now guided specifically into the middle of the groove by the cover slide, also known as the resin pipe.
- phase separators Different types and amounts of surface insulating materials (e.g. phase separators) represent barriers which prevent the resin from flowing optimally into the winding system 5.
- the rapid guidance of the resin flow 12 in the groove 3, in the middle of the groove and / or other positions within the axial extent of the groove 3 is also possible through a perforation 11 of the second layer 8 according to FIG 5.
- This perforation 11 can be about the The surface of the second layer 8 can be evenly distributed, and the second layer 8 can also have a different density of holes per unit area. The density of the holes in the central area of the layer 8 is greater. Likewise, or additionally, the diameter of the holes in the perforation 11 can be adjusted to the desired resin flow, so that the larger holes are arranged in the middle of the groove 3 . 4 and FIG.
- FIG. 5 show corrugations 10 of the first layer 7, which are aligned with the second layer 8 and divide the flow channel 13 into a plurality of smaller channels that run parallel and are not necessarily of the same size. In particular, a certain number of holes are assigned to the respective smaller channels.
