The invention relates to a method and a device for the positioned holding of a laminated core together with at least one layer accommodated in the laminated core from a plurality of conductor elements arranged distributed over the circumference of the laminated core to form a stator or rotor of an electrical machine.
The object of the present invention was to provide a method and a device by means of which a user is able to carry out safe handling operations of the laminated core together with the conductor elements which are displaceable longitudinally in the receiving grooves, without the conductor elements being in their pre-positioned relative position can change.
This object is achieved by a method and a device according to the claims.
The method according to the invention is used to hold at least one layer of a plurality of conductor elements arranged over the circumference of a laminated core and designed as rods in a position relative to the core of the conductor elements which is accommodated in a receiving groove which extends between a first end face and a second end face of a stator or rotor of an electrical machine, in which
at least one of the conductor elements is inserted into each of the receiving grooves,
- each of the at least one conductor elements in each case in which the receiving groove receiving the at least one conductor element is arranged to be longitudinally displaceable, and / 31
N2017 / 26100 AT-00
- The laminated core is surmounted on at least one of its end faces by end sections of the conductor elements, wherein
- The laminated core is held in position by a holding device, and
- All conductor elements of the at least one layer are each acted upon by a pressure force built up by the at least one pressure element at their end portions projecting above the laminated core from at least one pressure element of a printing device that is adjustable in the radial direction, and thus all the conductor elements are positioned relative to the laminated core in the direction of the longitudinal extent of the receiving grooves become.
It is advantageous in the method steps selected here that, after the sheet conductor stack has been introduced and loaded with the individual conductor elements, they can also be held stationary by the printing element or elements of the printing device relative to the sheet stack already held in position. By means of the holding device, the laminated core can not only be held in position, but handling operations can also be carried out with it. If the conductor elements are not positioned relatively in relation to the laminated core, they could be inadvertently displaced due to their free and longitudinally displaceable receptacle in the individual receiving grooves, which leads to faulty or unusable stators or rotors.
Due to the extensive arrangement of the conductor elements, a comprehensive application or build-up of pressure forces on all conductor elements must also be ensured, so as to create a secure relative positional fixation between the individual conductor elements and the laminated core even in the case of tolerances due to tolerances. Since a pressure force is applied to all conductor elements over a wide area, tolerance differences can be compensated better in order to reliably avoid an unintentional longitudinal displacement of individual conductor elements in the receiving grooves. If there are also possible foreign bodies, such as grains, insulation residues or tolerance-related differences in layer thickness of the insulating layer, safe axial longitudinal positioning of each of the individual conductor elements can still be achieved over the entire circumference. This makes it possible to move to / 31
N2017 / 26100-AT-00 the build-up of the compressive forces and the relative holding and fixing of all conductor elements with respect to the laminated core, with this unit comprising the laminated core and conductive elements, for example by means of the holding device, to be able to carry out subsequent manipulation processes. It is therefore no longer necessary to take the orientation and position into account, since an inadvertent shifting of the conductor elements with respect to the laminated core is reliably avoided. This pressure-force-based fixing position of the individual conductor elements is particularly advantageous when the longitudinal axis of the conductor stack has a vertical orientation and, due to the free, longitudinally displaceable reception of the conductor elements in the receiving grooves, a relative displacement of the latter cannot be prevented when the sheet metal package is removed from a supported storage area.
A variant of the method is also advantageous in which the laminated core is held in position by a holding arm of the holding device and holding elements located on the holding arm and adjustable in the radial direction are pressed against an inner surface of the laminated core. A secure and an axially predetermined orientation can thus be achieved when the laminated core has been received by the holding arm of the holding device. By the radial adjustment of the holding elements against the inner surface of the laminated core, it is possible to achieve a perfectly secure mounting and predetermined alignment of the longitudinal axis of the laminated core. This can e.g. in the form of a three-jaw chuck.
Furthermore, a procedure is advantageous in which the takeover of the laminated core together with the conductor elements is carried out in a position having a vertical orientation of a longitudinal axis extending between the two end faces, and subsequently the laminated core including the conductor elements is pivoted such that the longitudinal axis is in a horizontal position is spent. In this way, the laminated core, together with the conductor elements accommodated therein, can be supported with one of its end faces in a horizontal position, for example on a tool carrier or transport trolley, and at the same time a gravity-dependent, preferably automatic positioning of the individual conductor elements projecting beyond the laminated core can take place. So / 31
N2017 / 26100-AT-00 created the possibility of dispensing with additional alignment processes, wherein after the sheet metal package has been gripped, all conductor elements can be held in their position relative to the metal sheet package by the applied pressure force or the applied pressure forces.
A further advantageous procedure is characterized in that the at least one pressure element of the printing device is held on the holding device, in particular its holding arm, in a fixed position predetermined for this purpose, in particular on this. This ensures that the at least one pressure element of the printing device is also arranged stationary with respect to the holding device. Possible relative adjustment adjustments of the position of the pressure element with respect to the holding device, in particular its holding arm, can be carried out depending on the protrusion of the end sections of the conductor elements over the laminated core before the pressure force is applied.
A variant of the method is also advantageous, in which the at least one pressure element is received in a support element, which is preferably continuous over the circumference, and the support element is held on the holding device in a predetermined fixed position for this purpose. By providing at least one support element, the arrangement and positioning of the pressure element or elements can be carried out more easily seen over the circumference.
Another procedure is characterized in that each of the conductor elements is acted upon by the pressure force acting in the radial direction by its own pressure element. This ensures that each of the individual conductor elements can also be subjected to a compressive force for reliable relative clamping.
Furthermore, a procedure is advantageous in which the at least one pressure element is formed from an elastically expandable or elastically deformable material. Through the choice of the material of the pressure element, / 31
N2017 / 26100-AT-00 seen over the circumference, thanks to its elastic properties, a reliable build-up of the compressive forces can be achieved.
A further advantageous procedure is characterized in that the at least one pressure element is formed from an automatically resettable material. In this way, the built-up compressive force or the compressive forces which have previously been exerted or applied to the conductor elements can simply be withdrawn without additional adjusting means. In this way, the compressive force or the compressive forces can be built up in a simple manner, which after the assembly, due to the automatically resettable properties of the pressure element, leads to a simple release of the previously clamped conductor elements.
A variant of the method is also advantageous, in which the at least one pressure element is designed as a hose or ring that extends over the circumference. By designing the pressure element as a hose or ring, the pressure force can be applied to each of the conductor elements easily over the circumference, without additional adjustment and alignment work.
Another procedure is characterized when the hose is pressed against the end sections projecting beyond the laminated core by a pressure medium introduced into its interior. By introducing the pressure medium into the interior of the hose, a rapid and full extent of the pressure forces on all of the conductor elements can be carried out over the circumference. Alignment processes of the pressure elements on the respective arrangement of the conductor elements in the laminated core can thus also be omitted.
Furthermore, a procedure is advantageous in which all conductor elements of the at least one layer are pressed against the sheet stack by the pressure force built up by the at least one pressure element on a side facing away from the longitudinal axis of the sheet stack. By pressing the individual conductor elements against the laminated core on the side facing away from the longitudinal axis, they are thus pressed outward in the radial direction, so that at least one / 31
N2017 / 26100 AT-00
Pressure element on the radially inner side of the first layer can be found on conductor elements.
A further advantageous procedure is characterized in that all conductor elements of the at least one layer are pressed against the sheet stack by the pressure force built up by the at least one pressure element on a side facing the longitudinal axis of the sheet stack. Thus, the pressure force can be built up with at least one pressure element located in the radial direction on the outermost layer of conductor elements in the radial direction, and so this can be pressed in the radial direction towards the longitudinal axis.
A variant of the method is also advantageous, in which a plurality of conductor elements of the layers arranged one behind the other and / or immediately next to one another in the radial direction are accommodated in the laminated core and all of the conductor elements of each of the layers together either on a side facing away from the longitudinal axis of the laminated core or on one of the longitudinal axis of the The side facing the laminated core is pressed against the laminated core by the pressure force built up by the at least one pressure element. This makes it possible to be able to press a plurality of layers of conductor elements arranged one behind the other in a receiving groove either with an outside or with an inside pressure element arranged with respect to the conductor elements against the laminated core.
Another procedure is characterized in that a plurality of conductor elements of the layers arranged one behind the other and / or immediately next to one another in the radial direction are accommodated in the laminated core and all conductor elements of each of the layers of at least one first pressure element and of at least one second pressure element in each case in the radial direction be pressed. With the arrangement of the pressure elements on both sides as seen in the radial direction, they can be pressed securely against one another or against one another in the radial direction, as a result of which even better tolerance compensation and even more secure retention of the conductor elements to be held can be achieved.
/ 31
N2017 / 26100 AT-00
A further advantageous procedure is characterized in that the individual conductor elements of the at least one layer are positioned in relation to the laminated core in the axial direction prior to the application of the compressive force of the at least one pressure element. This allows a defined relative position of the individual conductor elements with respect to the laminated core to be defined even before the conductor elements are held in position with respect to the laminated core.
The device according to the invention is used to hold at least one layer of a plurality of conductor elements arranged around the circumference of a laminated core and designed as rods, with respect to the laminated core receiving the conductor elements in each case in a receiving groove extending between a first end face and a second end face to form a stator or Rotor of an electrical machine, and also serves to carry out the method. The device comprises the following features:
a holding device is provided, by means of which holding device the laminated core can be held in position, and
a pressure device is provided with at least one pressure element that is adjustable in the radial direction, by means of which at least one pressure element a pressure force can be exerted on those end sections of all conductor elements that protrude beyond the laminated core.
The advantage achieved thereby is that after the sheet stack has been introduced and loaded with the individual conductor elements, these can also be held stationary by the printing element or elements of the printing device relative to the sheet stack which has already been positioned. By means of the holding device, the laminated core can not only be held in position, but handling operations can also be carried out with it. If the conductor elements are not positioned relatively in relation to the laminated core, they could be inadvertently displaced due to their free and longitudinally displaceable receptacle in the individual receiving grooves, which leads to faulty or unusable stators or rotors.
/ 31
N2017 / 26100 AT-00
Due to the extensive arrangement of the conductor elements, a comprehensive application or build-up of pressure forces on all conductor elements must also be ensured, so as to create a secure relative positional fixation between the individual conductor elements and the laminated core even in the case of tolerances due to tolerances. Since a pressure force is applied to all conductor elements over a wide area, tolerance differences can be compensated better in order to reliably avoid an unintentional longitudinal displacement of individual conductor elements in the receiving grooves. If there are also possible foreign bodies, such as grains, insulation residues or tolerance-related differences in layer thickness of the insulating layer, safe axial longitudinal positioning of each of the individual conductor elements can still be achieved over the entire circumference. This makes it possible, after the build-up of the compressive forces and the relative holding and fixing of all conductor elements with respect to the laminated core, to carry out subsequent manipulation processes with this unit comprising the laminated core and conductive elements, for example by means of the holding device. It is therefore no longer necessary to take the orientation and position into account, since an inadvertent shifting of the conductor elements with respect to the laminated core is reliably avoided. This pressure-force-based fixing position of the individual conductor elements is particularly advantageous when the longitudinal axis of the conductor stack has a vertical orientation and, due to the free, longitudinally displaceable reception of the conductor elements in the receiving grooves, a relative displacement of the latter cannot be prevented when the sheet metal package is removed from a supported storage area.
Furthermore, it can be advantageous if the pressure device comprises at least one support element, which is preferably continuous over the circumference, which at least one support element is held on the holding device in a position that is stationary therewith, and the at least one pressure element is accommodated in the support element. By providing at least one support element, the arrangement and positioning of the pressure element or elements can be carried out more easily seen over the circumference.
/ 31
N2017 / 26100 AT-00
Another embodiment is characterized in that the printing device comprises a first support element and a second support element, both support elements preferably being formed continuously over the circumference, and at least one first pressure element being arranged in the first support element and at least one second pressure element being arranged in the second support element, and the second support element is arranged on the outside and at a distance from the first support element in the radial direction. With the arrangement of the pressure elements on both sides as seen in the radial direction, they can be pressed securely against one another or against one another in the radial direction, as a result of which even better tolerance compensation and even more secure retention of the conductor elements to be held can be achieved.
Another possible embodiment has the features that the at least one pressure element is formed from an elastically expandable or elastically deformable material and / or an automatically resettable material. Through the choice of the material of the pressure element, a reliable build-up of the pressure forces can be achieved over the circumference due to its elastic properties. Furthermore, it is thus easy to withdraw the built-up compressive force or the compressive forces that have previously been exerted or applied to the conductor elements without additional adjusting means. In this way, the compressive force or the compressive forces can be built up in a simple manner, which after the assembly, due to the automatically resettable properties of the pressure element, leads to a simple release of the previously clamped conductor elements.
A further embodiment provides that the at least one pressure element is designed as a hose or ring, which hose or ring is continuous over the circumference. By designing the pressure element as a hose or ring, the pressure force can be applied to each of the conductor elements easily over the circumference, without additional adjustment and alignment work.
Another embodiment is characterized in that from the at least one first pressure element to that of the longitudinal axis of the laminated core / 31
N2017 / 26100-AT-00 facing side compressive force can be exerted. By pressing the individual conductor elements against the laminated core on the side facing away from the longitudinal axis, they are thus pressed outward in the radial direction, so that at least one pressure element on the radially inner side of the first layer of conductor elements can be found to be sufficient.
A further preferred embodiment is characterized in that a second pressure force acting in the direction of the longitudinal axis of the laminated core can be exerted by the at least one second pressure element. Thus, the pressure force can be built up with at least one pressure element located in the radial direction on the outermost layer of conductor elements in the radial direction, and so this can be pressed in the radial direction towards the longitudinal axis.

To begin with, it should be noted that in the differently described embodiments, the same parts are provided with the same reference numerals or the same component names, and the disclosures contained in the entire description can be applied analogously to the same parts with the same reference numerals or the same component names. The location information selected in the description, e.g. above, below, to the side, etc., referring to the figure described and illustrated immediately, and if the position is changed, these are to be applied accordingly to the new position.
The term “in particular” is understood in the following to mean that it may be a more specific training or more detailed specification of an object or a method step, but does not necessarily have to represent a mandatory, preferred embodiment of the same or a mandatory procedure.
1 shows a possible design of a stator 1 to form an electrical machine, not shown. However, it would also be possible to apply and carry out the following description and design in a manner analogous to that for a rotor for forming an electrical machine. The following description relates only to a stator 1, but can also relate to a rotor
The assembly and a large number of production steps of the stator 1 can preferably be carried out automatically in a complex production system in a number of production stations, usually also fully automatically.
Basically, the stator 1 comprises a laminated core 2 and a multiplicity of conductor elements 3, 4 to be accommodated therein for generating a magnetic rotating field by coils.
In the present exemplary embodiment, the individual conductor elements 3, 4 are designed as straight rods in their undeformed starting position. The rods / 31
N2017 / 26100-AT-00 usually have a rectangular cross-section up to a square cross-section as well as a longitudinal extension and are formed from an electrically conductive material. Mostly it is a copper material. Therefore, these can also be called profile bars. In a known manner, the conductor elements 3, 4 can be surrounded with an insulating layer, not shown or designated, with the exception of contact regions formed thereon.
To form electrical coils and windings formed therefrom, a plurality of receiving grooves 5 are arranged or formed in the laminated core 2 distributed over the circumference, in which at least one of the conductor elements 3, 4, but preferably at least two of the conductor elements 3, 4, is received or arranged is or are. The receiving grooves 5 can extend in the axial direction and preferably in a parallel orientation with respect to a longitudinal axis 6 defined by the laminated core 2. However, it would also be possible to choose a non-parallel arrangement of the receiving grooves 5 with the conductor elements 3, 4 to be accommodated therein. Thus, the receiving grooves 5 each extend in the direction of the longitudinal axis 6 between a first end face 7 and a second end face 8 arranged at a distance therefrom.
The receiving grooves 5 each have a receiving groove cross section adapted to the cross-sectional dimension of the conductor element 3, 4 or, in the case of a plurality of conductor elements 3, 4 accommodated in the same receiving groove 5.
The laminated core 2 is composed of a large number of individual laminations or laminated metal laminations which are electrically insulated from one another and is delimited in the direction of the longitudinal axis 6 by the first end face 7 and the second end face 8 arranged at a distance therefrom. The two end faces 7, 8 are preferably arranged parallel to one another and running in a plane oriented in the normal direction with respect to the longitudinal axis 6. In the present exemplary embodiment, the package forms a hollow cylinder with an inner surface and an outer surface from the individual sheets or the sheet metal lamellae.
/ 31
N2017 / 26100 AT-00
At least one of the conductor elements 3, 4 is arranged in each of the receiving grooves 5, but preferably several, in particular two, three, four, five, six or even more conductor elements 3, 4. There may also be eight, ten, twelve or more conductor elements 3 , 4 may be included. A conductor element 3, 4 is provided as a minimal variant, but in this exemplary embodiment two conductor elements 3, 4 are shown and described in one receiving groove 5. Thus, the conductor elements 3 arranged on the inside in the radial direction form a first layer 9 and the conductor elements 4 arranged on the outside in the radial direction form a second layer 10.
Each of the conductor elements 3 and 4 comprises a first end section 11, 12 at its first end and a second end section 13, 14 at its opposite second end. In this exemplary embodiment, the first end sections 11, 12 protrude beyond the first end face 7 and the second End sections 13, 14 over the second end face 8 of the laminated core 2.
The conductor elements 3, 4, which are accommodated in the laminated core 2 in the individual receiving grooves 5 and mostly still undeformed, are in the region of each of the end faces 7, 8 in their end sections 11, 12; 13, 14 in one of the subsequent manufacturing steps, in a known manner, twisted or interlaced in the circumferential direction in order to subsequently connect a first of the end sections 11 of the first or inner layer 9 to a correspondingly further first end section 11 of the second or outer layer 10 in an electrically conductive manner , The same can preferably also be carried out with the respective second end sections 13, 14 in the region of the second end face 8.
Furthermore, it can also be advantageous if the individual conductor elements 3, 4, in addition to their insulating layer within the receiving grooves 5, are also preferably completely surrounded by their own insulating element 15.
The feeding or the introduction of the individual conductor elements 3, 4 into the respective receiving grooves 5 can take place step by step or in cycles, the laminated core 2 with its longitudinal axis 6 preferably being in a horizontal orientation. Since the mostly undeformed conductor elements 3, 4/31
N2017 / 26100-AT-00 are longitudinally displaceable in the respective receiving grooves 5, the handover to a subsequent processing station or production station must take into account or ensure the relative position of the conductor elements 3, 4 with respect to the laminated core 2.
In a positioning step to be carried out preferably before the transfer or transfer to the subsequent processing station or production station, the conductor elements 3, 4 can also be aligned in the axial direction with respect to one of the end faces 7, 8. This can e.g. in that the laminated core 2, together with the conductor elements 3, 4 already accommodated therein, is folded over from its preferably horizontal loading position into a vertical positioning position, in which the longitudinal axis 6 of the laminated core 2 has a vertical longitudinal orientation. The laminated core 2 can be supported on a positioning lug, the conductor elements 3, 4 preferably coming into contact with the individual receiving grooves 5 due to the force of gravity up to a preferably circumferential positioning element with one of their end sections 11, 12 or 13, 14. The distance between the positioning projection and the positioning element is to be selected in accordance with the predetermined projection of the ends of the conductor elements 3, 4 over one of the end faces 7, 8 of the laminated core 2.
This transport position can e.g. on a workpiece carrier that can be moved between individual work stations.
In this position of the longitudinal axis 6, which has a vertical orientation, the transfer or takeover to a subsequent processing station or production station is now to be carried out without changing the position of the conductor elements 3, 4 which have already been positioned in relation to the laminated core 2.
For this purpose, the method steps listed below can be used to hold at least one layer 9, 10 positioned, comprising a plurality of conductor elements 3, 4, which are distributed over the circumference of a laminated core 2 and are usually designed as straight rods, in a relative position with respect to the conductor elements 3, 4 each / 31
N2017 / 26100-AT-00 because in the laminated core 2 receiving between the two end faces 7, 8 extending receiving groove 5, optionally using a device 16 shown in FIGS. 2 to 4 or FIGS. 5 and 6 below.
The device 16 shown in FIGS. 2 to 4 and designed or provided for this purpose can be part of a work station and, in this exemplary embodiment, comprises a holding device 17, by means of which the laminated core 2 can be gripped and held in position. For this purpose, the holding device 17 can comprise a holding arm 18 with holding elements 19 located thereon. Several of the holding elements 19 can be provided distributed over the circumference, which can be pressed against the inner surface of the laminated core 2 after the insertion of the holding arm 18 into the interior of the laminated core 2.
Furthermore, the holding device 17 comprises a printing device 20 with a number of printing elements 21, 22 selected depending on the number of layers 9, 10 on conductor elements 3, 4. With only one layer 9, 10 on conductor elements 3, 4, only at least one printing element 21 could be used or 22 suffice can be found. By means of the pressure element or elements 21, 22, a pressure force “F” or, respectively, built up by the at least one pressure element 21, 22 can be applied to all conductor elements 3, 4 at their first end portions 11, 12 and / or second end portions 13, 14, which project above the laminated core 2 Pressure forces "F" are applied. Approximately the same compressive force should act or be applied to all end sections 11, 12 and / or 13, 14 at the same time. Possible arrangements are described below.
Before applying the compressive force or compressive forces, it is preferred, as has already been described above, to align the individual conductor elements 3, 4 of the at least one layer 9, 10 so as to be positioned in the axial direction with respect to the laminated core 2. As a reference plane or reference surface, e.g. the first end face 7 can be selected.
This takeover and the insertion of the holding arm 18 with the holding elements 19 can still be in a vertical orientation
N2017 / 26100-AT-00 between the two end faces 7, 8 extending longitudinal axis 6 are performed. The laminated core 2 together with the conductor elements 3, 4 can subsequently be pivoted such that the longitudinal axis 6 has a horizontal position.
Before the pivoting process, if this is necessary at all, all conductor elements 3, 4 of the at least one layer 9, 10 are to be kept positioned relative to the laminated core 2 in the direction of the longitudinal extent of the receiving grooves 5. This is done by means of the printing device 20.
In order to avoid a relative displacement of the printing device 20 with respect to the holding device 17, in particular the holding arm 18 thereof, the latter, in particular the at least one pressure element 21, 22, must be held or fastened thereon in a predetermined fixed position. This can e.g. by means of its own support elements 23, 24 of the printing device 20.
In the present exemplary embodiment, two layers 9 and 10 are provided on conductor elements 3 and 4. The individual conductor elements 3, 4 are arranged one behind the other in the radial direction. However, it would also be possible not only to arrange a plurality of conductor elements 3, 4 one behind the other in the radial direction in the same receiving groove 5, but also to arrange a plurality of conductor elements 3, 4 directly next to one another for each layer 9, 10. More than two layers could also be provided one behind the other in the radial direction.
The safest mounting and clamping by the pressure element or elements 21, 22 can be achieved due to tolerances if at least one of the pressure elements 21, 22 is arranged on each side (outside and inside) of the conductor elements 3, 4, viewed in the radial direction. Here, the first pressure element 21 is arranged in the radial direction on the inside with respect to the first layer 9 and the second pressure element 22 is arranged on the outside in the radial direction with respect to the second layer 10. The layers 9, 10 and thus the conductor elements 3, 4 which are arranged directly behind one another in the radial direction can thus be pressed against one another.
/ 31
N2017 / 26100 AT-00
A first support element 23 and a second support element 24 can be provided here for fastening and holding the first pressure element 21 and the second pressure element 22. In this case, the pressure elements 21, 22 are held in a predetermined fixed position with respect to the holding device 17 by means of the support elements 23, 24. Furthermore, the at least one first pressure element 21 can be accommodated or arranged in the first support element 23 and the at least one second pressure element 22 in the second support element 24.
It is provided here that the second support element 24 is arranged on the outside and at a distance from the first support element 23 in the radial direction. The support elements 23, 24 can preferably be formed continuously over the circumference. As the profile shape of the support elements 23, 24, e.g. a U-profile can be selected. The respective open side is to be turned towards the respective layer 9, 10 to which the compressive force is to be applied.
In the present exemplary embodiment, the pressure elements 21, 22 are designed as a hose that is preferably continuous over the circumference. Furthermore, the material of the pressure elements 21, 22 should be designed to be elastically expandable or elastically deformable. A material that also has automatically resettable properties can also be used with preference. This means that the elastic properties of the selected material can also be used to compensate for tolerances. For example, elastomers, rubber, rubber or the like could be used.
If the at least one pressure element 21, 22 is designed as a tube, a pressure medium can be introduced into the interior of the tube for the application of the pressure force. Due to the enlargement of the cross section, the hose is used as a pressure element against the end sections 11, 12; 13, 14 pressed. For this purpose, each interior of the hose is connected in line via a supply line 25 to a pressure generator, not shown, in order to be able to supply the pressure medium to the interior and to discharge it from the interior. A gaseous and / or a liquid pressure medium can preferably be used. For this purpose, air, in particular compressed air, can preferably be used as the pressure medium.

It would also be possible to design the at least one pressure element 21, 22 as an elastic ring. For this purpose, separate adjustment means would have to be provided in order to carry out the adjustment movement and to be able to build up the pressure force or the pressure forces.
Irrespective of this, it would also be possible to apply each of the conductor elements 3, 4 with their own pressure element 21, 22 with the pressure force acting in the radial direction. This means that a large number of pressure elements have to be provided so that the individual pressure forces can be built up.
Irrespective of this, it would also be possible, as indicated schematically in FIGS. 5 and 6, to provide the at least one pressure element 21, 22 only on one side of the layer 9, 10 or the layers 9, 10. The end sections 11, 12 and / or 13, 14 each projecting above the laminated core 2 can thus be pressed against the laminated core 2. In the case of a plurality of layers 9, 10, all conductor elements 3, 4 of each of the layers 9, 10 could jointly either on a side facing away from the longitudinal axis 6 of the laminated core 2 or on a side facing the longitudinal axis 6 of the laminated core 2 from the at least one pressure element 21, 22 pressure force built up can be pressed against the laminated core 2. If only one layer 9 or 10 is provided on conductor elements 3 or 4, one layer 9 or 10 with all conductor elements 3 or 4 can either be on a side facing away from the longitudinal axis 6 of the laminated core 2 against the laminated core 2 or on one of the longitudinal axis 6 of the laminated core 2 facing side are pressed against the laminated core 2.
