Description

Die Erfindung bezieht sich auf ein magnetisches Antriebssystem für eine Schalteinrichtung der im Oberbegriff von Patentanspruch 1 angegebenen Art.The invention relates to a magnetic drive system for a switching device specified in the preamble of claim 1. Art.

Eine derartiges bipolares Antriebssystem ist z. B. aus der DE 197 09 089 A1 bereits bekannt. Der Anker besteht hierbei aus einem massiven magnetischen Eisenwerkstoff, wodurch er sich kostengünstiger fertigen lässt als ein aus geschichteten Elektroblechen zusammengesetzter Anker und häufig auch eine größere Langzeitstabilität aufweisen wird. Dafür hat der massive Anker an sich den Nachteil, dass gegenüber Ankern aus geschichtetem Elektroblech mehr Wirbelstromverluste auftreten und eine stärkere Remanenz vorhanden ist, die u. a. das Lösen der Schaltkontakte beim Umschalten erschwert. Um die Wirbelstromverluste zu reduzieren, ist der Anker mit länglichen Hohlkanälen versehen, die aus schmalen Schlitzen bestehen und sich in Vorschubrichtung des Ankers und somit in Richtung der magnetischen Feldlinien erstrecken. Die vorgesehenen Schlitze an den Schmalseiten des Ankers schwächen den quaderförmigen Anker dabei über jeweils ein Drittel seiner Querschnittsbreite und über seine gesamte Länge. Aus den Breitseiten des Ankers sind zudem nebeneinander mehrere parallele Schlitze ausgespart, die sich allerdings nicht über die gesamte Länge des Ankers erstrecken sondern in einem Abstand zu den Stirnseiten des Ankers enden. Insgesamt ist die mechanische Stabilität des Ankers aber durch die Schlitze erheblich beeinträchtigt. Deshalb ist vorgesehen, die Stabilität des Ankers nach Einbringen der Schlitze durch Füllen derselben mit Isoliermaterial wieder zu erhöhen. Gerade weil diese Schlitze aus technischen Gründen möglichst eng sein sollen, ist das Auffüllen der Schlitze technisch aber entsprechend schwierig und verteuert die Herstellung des Ankers erheblich.
Um der stärkeren Remanenz des Ankers zu begegnen, sollen die Übergänge zwischen der Kontaktfläche des Ankers und den Jochblechen bedarfsgerecht angepasst werden können. Eine Verminderung der Kontaktfläche führt zwar zu einem verbesserten Ansprechverhalten im Sinne einer kürzeren Schaltzeit, muss jedoch mit dem Nachteil einer reduzierten Haftkraft des Ankers erkauft werden. Da eine zu geringe Haftkraft des Ankers sich jedoch nachteilig auf die Betriebssicherheit des magnetischen Antriebssystems auswirkt, wird das bekannte Antriebssystem den konstruktiven Anforderungen bei vielen Anwendungsfällen nicht gerecht werden können.Such a bipolar drive system is z. B. from the DE 197 09 089 A1 already known. The anchor here consists of a solid magnetic iron material, which makes it cheaper to manufacture than an assembled from layered electrical sheets anchor and often will have a greater long-term stability. For the massive anchor itself has the disadvantage that compared to anchors made of layered electrical steel more eddy current losses occur and a stronger remanence is present, which makes it difficult, inter alia, the release of the switching contacts when switching. In order to reduce the eddy current losses, the armature is provided with elongated hollow channels, which consist of narrow slots and extend in the feed direction of the armature and thus in the direction of the magnetic field lines. The slots provided on the narrow sides of the anchor weaken the cuboid anchor in each case over one third of its cross-sectional width and over its entire length. From the broad sides of the anchor next to each other several parallel slots are recessed, which do not extend over the entire length of the armature but end at a distance to the end faces of the armature. Overall, the mechanical stability of the armature but significantly affected by the slots. Therefore, it is provided to increase the stability of the anchor after introducing the slots by filling them with insulating material again. Precisely because these slots should be as tight as possible for technical reasons, that is Filling the slots technically but correspondingly difficult and significantly increases the cost of making the anchor.
In order to counteract the stronger remanence of the armature, the transitions between the contact surface of the armature and the yoke plates should be able to be adapted as needed. Although a reduction of the contact surface leads to an improved response in terms of a shorter switching time, but must be bought with the disadvantage of a reduced adhesive force of the anchor. Since too low adhesive force of the armature, however, adversely affects the reliability of the magnetic drive system, the known drive system can not meet the design requirements in many applications.

Der Erfindung liegt daher die Aufgabe zugrunde, ein magnetisches Antriebssystem der im Oberbegriff von Anspruch 1 angegebenen Art dahingehend weiterzuentwickeln, dass die Stabilität des Ankers durch dessen Gestaltung zur Reduzierung der Wirbelstromverluste nicht übermäßig reduziert ist.The invention is therefore based on the object to further develop a magnetic drive system specified in the preamble of claim 1 to the effect that the stability of the armature is not excessively reduced by the design for reducing the eddy current losses.

Diese Aufgabe wird durch die Merkmale von Patentanspruch 1 gelöst.This object is solved by the features of claim 1.

Vorteilhafte Ausgestaltungen der Erfindung sind Gegenstand der abhängigen Ansprüche.Advantageous embodiments of the invention are the subject of the dependent claims.

Das erfindungsgemäße magnetische Antriebssystem für eine Schalteinrichtung umfasst ein Magnetjoch, in dem ein massiver Anker aus magnetischem Werkstoff zwischen zwei entgegen gesetzten Endlagen linear schiebegeführt ist, und wenigstens einen Permanentmagneten zur Erzeugung eines magnetischen Flusses in dem Magnet joch und wenigstens eine Spule, durch die der Anker zwischen seinen Endlagen hin- und her bewegbar ist, wobei der Anker zur Vermeidung von Wirbelstromverlusten mit länglichen Kanälen versehen ist und die Kanäle im Anker an ihrem Umfang umlaufend geschlossen sind.The magnetic drive system according to the invention for a switching device comprises a magnetic yoke, in which a solid armature of magnetic material is linearly slidably guided between two opposite end positions, and at least one permanent magnet for generating a magnetic flux in the magnet yoke and at least one coil, through which the armature between its end positions back and forth, the armature to avoid eddy current losses is provided with elongated channels and the channels are circumferentially closed in the anchor at its periphery.

Durch die Anordnung von umlaufend geschlossenen Kanälen (Hohlkanälen) im Anker wird auf einfache Weise erreicht, dass die Stabilität des Ankers kaum beeinträchtigt wird. Somit kann das technisch aufwändige Füllen der Kanäle entfallen.The arrangement of circumferentially closed channels (hollow channels) in the anchor is achieved in a simple manner that the stability of the armature is hardly affected. Thus, the technically complex filling of the channels can be omitted.

Vorzugsweise bestehen die in den Anker eingebrachten Kanäle aus Bohrungen mit relativ geringem Hohlquerschnitt. Solche Bohrungen müssen nicht zwingend kreisrund sein, sondern können auch z. B. einen ovalen Querschnitt aufweisen. Möglichst sollte der Hohlquerschnitt aber so gestaltet sein, dass an der den Hohlquerschnitt begrenzende Umfangswand keine scharfen Ecken vorhanden sind.Preferably, the introduced into the anchor channels consist of holes with a relatively small hollow cross-section. Such holes do not necessarily have to be circular, but can also z. B. have an oval cross-section. If possible, however, the hollow cross-section should be designed so that there are no sharp corners on the peripheral wall delimiting the hollow cross-section.

Bei nachträglich in den Ankerblock eingebrachten Bohrungen ist es aber vorteilhaft, wenn die Bohrungen kreisrund sind, weil sie sich dann kostengünstig mit Drillbohrern erzeugen lassen.In subsequently introduced into the anchor block holes, it is advantageous if the holes are circular, because they can then be produced inexpensively with drill drills.

Vor der technischen Wirkung her und auch fertigungstechnisch ist es günstig, wenn die Bohrungen im Anker gerade Durchgangsbohrungen sind. Alternativ können die Bohrungen als Sacklochbohrungen ausgebildet sein, die von beiden Seitenflächen aus gebohrt werden.Before the technical effect forth and also manufacturing technology, it is advantageous if the holes in the anchor are straight through holes. Alternatively, the holes may be formed as blind holes, which are drilled from both side surfaces.

Die technische Wirkung eines Spalts im Hinblick auf die Reduzierung der Wirbelstromverluste lässt sich näherungsweise erreichen, wenn mehrere Kanäle des Ankers mit geringem Abstand zu einer Lochreihe oder zu mehreren Lochreihen aneinandergereiht sind. Mehrere Lochreihen werden dabei zweckmäßig parallel zueinander jeweils entlang einer geraden Linie ausgerichtet.The technical effect of a gap with respect to the reduction of eddy current losses can be approximately achieved when several channels of the armature are lined up with a small distance to a row of holes or multiple rows of holes. Several rows of holes are expediently aligned parallel to each other along a straight line.

Besonders wirkungsvoll ist es, wenn die von den Ankerführungsstangen durchdrungenen Stirnseiten des Ankerblocks über mindestens eine Lochreihe oder mehrere, insbesondere zwei, drei oder vier parallele Lochreihen von Durchgangslöchern verbunden sind, die parallel zu den Breitseiten des Ankers nahe dem Loch der Ankerführungsstange verlaufen. Mittig zwischen diesen Lochreihen kann mindestens eine weitere Lochreihe oder mehrere, insbesondere zwei, drei oder vier Lochreihen vorgesehen werden, die sich entlang der Mittellängsebene des Ankers zwischen dessen Schmalseiten erstreckt bzw. erstrecken.It is particularly effective if the ends of the anchor block penetrated by the armature guide rods are connected via at least one row of holes or several, in particular two, three or four parallel rows of through holes which run parallel to the broad sides of the armature near the hole of the armature guide rod. At least one further row of holes or several, in particular two, three or four rows of holes can be provided centrally between these rows of holes, which extend or extend along the central longitudinal plane of the armature between its narrow sides.

Eine weitere technische Verbesserung wird erzielt, wenn auch die Breitseiten des Ankerblocks über mehrere Reihen weitgehend von Durchgangsbohrungen perforiert sind. Hier können neben der Querebene der Ankerführungsstange zwei Felder mit Bohrungsreihen angeordnet werden. Sind zwei Ankerführungsstangen in entgegen gesetzten Sacklochbohrungen des Ankers befestigt, so kann ein zwischen den Sacklochenden verbleibender Ankerbereich mit Vollmaterial zusätzlich noch für eine zentrale Anordnung einer Durchgangsbohrung genutzt werden.Another technical improvement is achieved when the broad sides of the anchor block are perforated over several rows largely of through holes. Here, two fields with rows of holes can be arranged next to the transverse plane of the armature guide rod. If two armature guide rods are fastened in opposite blind holes of the armature, an armature area with solid material remaining between the blind hole ends can additionally be used for a central arrangement of a through-hole.

Der in allen drei Raumrichtungen von Bohrungen durchsetzte Ankerblock sorgt neben der Reduzierung der Wirbelstromverluste auch bereits für eine deutliche Herabsetzung der Remanenzneigung. Die Verminderung der Remanenz wird nochmals größer, wenn auch die mit den Anschlagflächen des Ankers zusammenwirkenden Gegenflächen von jeweils einer oder von jeweils mehreren Lochreihen perforiert sind.The anchor block, interspersed with bores in all three spatial directions, not only reduces eddy current losses but also significantly reduces the remanence tendency. The reduction of the remanence is even greater, although the cooperating with the abutment surfaces of the armature mating surfaces of one or more rows of holes are perforated.

Das Magnetsystem hat insgesamt gegenüber dem bekannten System mit Schlitzen als Hohlkanäle den Vorteil, dass die Ausbildung von Wirbelströmen in allen drei Achsrichtungen behindert und somit reduziert wird. Die Betriebssicherheit bleibt dabei nahezu ungeschmälert erhalten, da sich die Haftkraft bei gleicher Gesamtinduktion nur unwesentlich reduziert und gleichzeitig die Remanenzinduktion des Magnetkreises absinkt. Letzterer Effekt beruht im Wesentlichen darauf, dass die magnetische Induktion im Anker lediglich lokal gezielt in den Sättigungsbereich hinein erhöht und dadurch die lokale Permeabilität abgesenkt wird. Infolge der zahlreichen Kanäle im Anker ist zudem die Ankermasse geringer, so dass sich insgesamt eine geringere Remanenz verbunden mit verbesserten dynamischen Eigenschaften des Ankers bzw. des gesamten Magnetsystems ergibt.The magnet system has the advantage over the known system with slots as hollow channels that the formation of eddy currents in all three axial directions obstructed and thus reduced. The reliability remains almost undiminished, since the adhesive force is only slightly reduced at the same Gesamtinduktion and simultaneously decreases the remanence of the magnetic circuit. The latter effect is based essentially on the fact that the magnetic induction in the anchor increases only locally targeted in the saturation region and thereby the local permeability is lowered. As a result of the numerous channels in the armature anchor mass is also lower, so that overall results in a lower remanence combined with improved dynamic properties of the armature or the entire magnet system.

Diese Struktur 1 umfasst einen quaderförmigen Rahmen, der aus zwei Magnet jochen 2 und 3 unter Zwischenfügung von zwei Lagerplatten 4 und 5 zusammengesetzt ist. Beide Magnetjoche 2 und 3 sind spiegelsymmetrisch gestaltet und besitzen an den beiden Enden jeweils um 90 Grad abgewinkelte Jochschenkel, so dass sie hinsichtlich ihrer Grundform etwa U-förmig gestaltet sind. Die planen Endflächen der gegeneinander gerichteten Jochschenkel der Magnet joche 2 und 3 liegen oben flächig an der zugewandten Seitenfläche der Lagerplatte 4 und unten an der zugewandten Seitenfläche der Lagerplatte 5 an, wobei die korrespondierenden Jochschenkel über die Lagerplatten 4 bzw. 5 miteinander verbunden sind. Im Mittelbereich zwischen den Jochschenkeln ragt von den Magnet jochen 2 und 3 jeweils ein vorspringender Polschenkel ab, wobei die einander gegenüberliegenden Polschenkel entsprechend den Jochschenkeln gegeneinander gerichtet sind. Auf den einander mit Abstand gegenüberliegenden Enden der Polschenkel sind plattenförmige Permanentmagnete 6 bzw. 7 befestigt.In FIG. 1 is a supporting structure 1 of a not shown in the entirety permanent magnetic drive system to operate a switching device to see. This structure 1 comprises a cuboidal frame, which is composed of two magnet yokes 2 and 3 with the interposition of two bearing plates 4 and 5. Both magnetic yokes 2 and 3 are designed mirror-symmetrically and have at both ends in each case angled by 90 degrees yoke legs, so that they are designed approximately U-shaped with respect to their basic shape. The flat end surfaces of the oppositely directed yoke legs of the magnetic yokes 2 and 3 are up flat on the facing side surface of the bearing plate 4 and down to the facing side surface of the bearing plate 5, wherein the corresponding yoke legs are connected to each other via the bearing plates 4 and 5 respectively. In the central region between the yoke legs protrudes from the magnet yokes 2 and 3 each have a projecting pole leg, wherein the opposite pole legs are directed according to the yoke legs against each other. On the mutually at opposite ends of the pole leg plate-shaped permanent magnets 6 and 7 are fixed.

Zwischen den planparallelen Permanentmagneten 6 und 7 liegt mit geringem Abstand zu diesen ein quaderförmiger Anker 8 im Jochrahmen, der in der gezeichneten Position an der Lagerplatte 5 aufliegt. Der Anker 8 umfasst auch zwei Ankerführungsstangen 9 die mittig von der Oberseite bzw. der Unterseite des Ankerblocks abstehen und geometrisch koaxial zueinander angeordnet sind. Die Ankerführungsstangen 9 durchsetzen eine Lagerbohrung 10 in der ihnen zugeordneten Lagerplatte 4 bzw. 5 mit wenig Umfangsspiel und stehen mit einem Endbereich aus der Lagerbohrung 10 ihrer Lagerplatte 4 bzw. 5 heraus, so dass der Anker 8 mittels der Führungsstangen 9 vertikal linear schiebegeführt ist. Der Jochrahmen wäre im Zusammenbau noch mit zwei Spulen den Polschenkeln und den Jochschenkeln versehen, durch deren Magnetfeld der Anker 8 bei entsprechender Polrichtung nach Überwindung seiner Anhaftung an der Lagerplatte 5 in seine obere Endlage verschoben würde, in der sein Vorschub durch Anschlagen an der Unterseite der Lagerplatte 4 begrenzt würde. Nach Umkehrung der Polrichtung des Magnetfeldes würde er nach Überwindung der Anhaftung durch Magnetkräfte wieder nach unten in die gezeigte Endlage auf die Lagerplatte 5 niedergedrückt und in der Anlagestellung gehalten. Die Wirkungsweise solcher Magnetantriebe ist als solche bekannt, so dass hier auf weitergehende Erläuterungen verzichtet wird.Between the plane-parallel permanent magnets 6 and 7 is at a small distance to this a cuboidal anchor 8 in the yoke frame, which in the position shown on the bearing plate 5 rests. The armature 8 also comprises two armature guide rods 9 which project centrally from the upper side or the lower side of the armature block and are arranged geometrically coaxial with one another. The armature guide rods 9 pass through a bearing bore 10 in their associated bearing plate 4 and 5 with little circumferential clearance and stand out with an end portion of the bearing bore 10 of their bearing plate 4 and 5, so that the armature 8 is vertically linearly slidably guided by the guide rods 9. The yoke frame would be in assembly still with two coils Polschenkeln and yoke legs provided by the magnetic field of the armature 8 would be shifted with appropriate polarity after overcoming its attachment to the bearing plate 5 in its upper end position in which its feed by striking the bottom of the Bearing plate 4 would be limited. After reversal of the polarity of the magnetic field he would be depressed after overcoming the adhesion by magnetic forces back down to the end position shown on the bearing plate 5 and held in the contact position. The mode of action of such magnetic drives is known as such, so that no further explanation is provided here.

Die Magnetjoche 2 und 3 bestehen hier aus einer Vielzahl dünner Jochbleche, die zu dem gezeigten, dicken Jochblechstapel gefügt sind. Demgegenüber bestehen der Anker 8 sowie die Lagerplatten 4 und 5 aus Blöcken ferromagnetischen Materials bekannter Art, insbesondere aus einer entsprechenden Eisenlegierung.The magnetic yokes 2 and 3 consist here of a plurality of thin yoke plates, which are joined to the shown thick Jochblechstapel. In contrast, the armature 8 and the bearing plates 4 and 5 consist of blocks of ferromagnetic material of known type, in particular of a corresponding iron alloy.

Zur Reduzierung der Wirbelstromverluste und der Remanenz des Ankers 8 sowie der Lagerplatten 4 und 5 sind in den massiven Block des Ankers 8 eine Vielzahl von Kanälen (Hohlkanälen) 11, 12 und 13 integriert, die hier einen übereinstimmenden Durchmesser von 2 mm bis 3 mm aufweisen, alle als Durchgangsbohrungen ausgebildet sind und sich nur hinsichtlich ihrer Länge unterscheiden, da sie den Block des Ankers 8 in unterschiedlichen Richtungen durchsetzen. Die Kanäle 11, 12 und 13 können alternativ auch als Sacklochbohrungen ausgebildet sein, die von beiden Seitenflächen aus gebohrt werden.To reduce the eddy current losses and the remanence of the armature 8 and the bearing plates 4 and 5, a plurality of channels (hollow channels) 11, 12 and 13 are integrated in the solid block of the armature 8, which here have a matching diameter of 2 mm to 3 mm , all as through holes are formed and differ only in their length, since they enforce the block of the armature 8 in different directions. The channels 11, 12 and 13 may alternatively be formed as blind holes, which are drilled from both side surfaces.

Wie in Verbindung mit den Figuren 2 und 3 deutlicher zu erkennen ist, gehen die Kanäle 11 von der oberen Stirnseite des Ankers 8 aus, verlaufen parallel zur Mittellängsachse der Ankerführungstangen 9 und somit rechtwinklig zur planen Stirnseite bis sie auf der gegenüberliegenden Stirnseite münden. Dabei sind zwei Reihen mit jeweils sechs Kanälen 11 vorhanden, wobei die Kanäle 11 in jeder der beiden Reihen jeweils einen Abstand von ca. 4 mm zum benachbarten Kanal 11 aufweisen. Diese Reihen verlaufen parallel zu den langen Seitenkanten der Stirnseiten und auf entgegen gesetzten Seiten einer mittig in auf der Stirnseite angeordnete Sacklochbohrung 14 mit Innengewinde, in welche die Ankerführungsstange 9 hineingedreht ist. Quer zu diesen Kanälen 11 sind die Kanäle 12 angeordnet, die von einer Schmalseite des Ankers 8 ausgehen und auf der gegenüberliegenden Schmalseite des Ankers 8 münden. Diese insgesamt fünf Kanäle 12 bilden eine gerade Reihe, die mittig zwischen den langen Seitenkanten der Schmalseite angeordnet ist, wie in Verbindung mit Figur 4 zweifelsfrei zu sehen ist. Diese Kanäle 12 verlaufen dadurch aber auch mittig zwischen den beiden Reihen mit den Kanälen 11 und durchdringen auch die Anordnungsebene der Ankerführungsstangen 9. Falls keine Schwächung der Bohrungswand der Sacklochbohrungen 14 erfolgen soll, können die Kanäle 12 deshalb alternativ auch als Sacklochbohrungen ausgebildet sein und in einem Abstand vor der Sacklochbohrung 14 enden. Solche Sacklochbohrungen als Kanäle 12 sollten dann möglichst im gleichen Abstand von der Sacklochbohrung 14 enden wie der seitliche Abstand der Kanäle 11 auf der Stirnseite des Ankers 8. Dieser Abstand ist in der frontalen Draufsicht gemäß Figur 7 gut zu erkennen. In diesem Fall müssten die Kanäle 12 aber von den entgegen gesetzten Stirnseiten aus gebohrt werden, was einen entsprechenden Mehraufwand bei der Herstellung des Ankers 8 zur Folge hätte.As in connection with the FIGS. 2 and 3 can be seen more clearly, the channels 11 go from the upper end face of the armature 8, parallel to the central longitudinal axis of the anchor guide rods 9 and thus perpendicular to the flat end face until they open on the opposite end. In this case, two rows, each with six channels 11 are present, wherein the channels 11 in each of the two rows each have a distance of about 4 mm to the adjacent channel 11. These rows extend parallel to the long side edges of the end faces and on opposite sides of a centrally located on the front side blind hole bore 14 with internal thread, in which the armature guide rod 9 is screwed. Transverse to these channels 11, the channels 12 are arranged, which emanate from a narrow side of the armature 8 and open on the opposite narrow side of the armature 8. This total of five channels 12 form a straight row, which is arranged centrally between the long side edges of the narrow side, as in connection with FIG. 4 beyond doubt. However, these channels 12 thereby also run centrally between the two rows with the channels 11 and penetrate the assembly plane of the armature guide rods 9. If no weakening of the bore wall of the blind holes 14 should take place, the channels 12 may therefore alternatively be formed as blind holes and in one Distance before the blind hole 14 ends. Such blind holes as channels 12 should then end as possible at the same distance from the blind hole 14 as the lateral distance of the channels 11 on the front side of the armature 8. This distance is in the frontal plan view according to FIG. 7 clearly visible. In this case, however, the channels 12 would have to be drilled from the opposite end sides, which would result in a corresponding additional expenditure in the production of the armature 8.

Ebenfalls quer zu den Kanälen 11 und in erheblich größerer Anzahl sind die Kanäle 13 eingebracht, die sich alle rechtwinklig zur Längsmittelebene des Ankers 8 erstrecken. Dabei gehen die Kanäle 13 von einer Breitseite des Ankers 8 aus und münden in die gegenüberliegende Breitseite ein. Das Lochbild auf der Breitseite umfasst dabei zwei rechteckige Lochfelder, die aus drei parallelen Reihen mit jeweils sechs Hohlkanälen 13 bestehen, wobei die Hohlkanäle 13 in der Reihe und seitlich einen übereinstimmenden Abstand voneinander aufweisen. Diese Lochfelder liegen beidseitig eines Mittelbereichs des Ankers 8, in dem die Ankerführungsstangen 9 angeordnet sind.Also transversely to the channels 11 and in a considerably larger number, the channels 13 are introduced, all of which extend at right angles to the longitudinal center plane of the armature 8. The channels 13 go from one broad side of the armature 8 and open into the opposite broad side. The hole pattern on the broad side comprises two rectangular hole fields, which consist of three parallel rows, each with six hollow channels 13, wherein the hollow channels 13 in the row and laterally have a matching distance from each other. These hole fields are on both sides of a central region of the armature 8, in which the armature guide rods 9 are arranged.

Zwischen den beiden Lochfeldern aus Hohlkanälen 13 ist zusätzlich zentral ein einzelner Kanal 13' angeordnet, der ebenfalls eine die Breitseiten verbindende Durchgangsbohrung bildet. Wie aus der Frontalansicht nach Figur 5 in Verbindung mit der Schnittdarstellung nach Figur 6 zu ersehen ist, passiert der Hohlkanal 13' hierbei einen Vollmaterialbereich des Ankerblocks, der zwischen den Enden der beiden Sacklochbohrungen 14 verblieben ist. Somit wird die Stabilität des Ankers 8 durch den Kanal 13' nicht nennenswert beeinträchtigt.Between the two hole fields of hollow channels 13, a single channel 13 'is additionally centrally disposed, which also forms a connecting the broad sides through hole. As seen from the frontal view FIG. 5 in conjunction with the sectional view to FIG. 6 can be seen, the hollow passage 13 'in this case a solid material area of the anchor block, which has remained between the ends of the two blind holes 14. Thus, the stability of the armature 8 is not significantly affected by the channel 13 '.

Neben den Kanälen im Anker 8 befinden sich auch in den Lagerplatten 4 und 5 Kanäle 15, die sich achsparallel zu den Kanälen 11 erstrecken. Von den Kanälen (Hohlkanälen) 15 sind zwei Reihen mit jeweils sechs Kanälen 15 vorhanden, die vorzugsweise kongruent zu den Kanälen 11 im Anker 8 angeordnet sind.In addition to the channels in the armature 8 are also in the bearing plates 4 and 5 channels 15 which extend axially parallel to the channels 11. Of the channels (hollow channels) 15 two rows, each with six channels 15 are present, the are preferably arranged congruent to the channels 11 in the armature 8.
