Description
Bekannt sind Elektromotoren mit lamelliertem Ständerblechpaket, mit offenliegender Ständerwicklung und mit einem in einer Kapsel flüssigkeitsdicht eingeschlossenen Läufer für den direkten Antrieb von Pumpen, Kompressoren τι. dgl. zur Verdichtung von schädlichen (giftigen) Gasen u. dgl., also insbesondere zum unmittelbaren Antrieb von Kompressoren für Kälteanlagen.Are known electric motors with laminated stator core, with exposed Stator winding and with a rotor enclosed in a liquid-tight capsule for the direct drive of pumps, compressors τι. Like. For the compression of harmful (Poisonous) gases and the like, especially for the direct drive of compressors for refrigeration systems.
Bei den bekannten Motoren dieser Art besteht die Läuferkapsel aus nicht leitendem und nicht magnetisierbarem Werkstoff. Dies ergibt bekanntlich, besonders infolge des erforderlichen verhältnismäßig großen Luftspalig tes zwischen Ständer und Läufer, ungünstige elektrische Verhältnisse. Unter diesen Gesichtspunkten hat man bekanntlich bereits, allerdings zum Zwecke einer Kapselung der Ständerwicklung, das lamellierte Ständereisen selbst, soweit es in der Nähe des Luftspaltes liegt, dazu verwendet, um die füissigkeitsdichte Trennung zwischen dem Ständer- und Läuferraum herbeizuführen.In the known motors of this type, the rotor capsule consists of non-conductive and non-magnetizable material. As is well known, this results, especially as a result of the required relatively large Luftspalig tes between stator and rotor, unfavorable electrical conditions. From this point of view, it is well known that however, for the purpose of encapsulating the stator winding, the laminated stator iron itself, as far as it is close to the air gap, is used to improve the liquid density To bring about a separation between the stator and rotor space.
Erfindungsgemäß geschieht das gleiche bei einer Läuferkapsel, so daß der Vorteil der offenliegenden Ständerwicklung, d. h. also ' die leichte Zugänglichkeit des Ständers, erhalten bleibt. Damit außerdem für Reparaturen, die bisher ein Ablassen· des Gases der Kälteanlage o. dgl. und somit für die Wiederinbetriebnahme .eine Neuauffüllung oder eine NachfüHung der Anlage erforderlich machten, der Ständer nebst seiner Wicklung leicht demontiert werden kann, wird das Ständerblechpaket in zwei konzentrisch ineinander ,angeordnete Blechpakete unterteilt, von denen nur der innere Teil den Ersatz der Läuferkapsel bildet, während der äußere, abnehmbare Teil die Ständerwicklung trägt.According to the invention the same happens with a rotor capsule, so that the advantage of exposed stator winding, d. H. so 'the easy accessibility of the stand remain. This is also used for repairs that previously involved releasing the gas from the Refrigeration system or the like and thus for restarting. A refill or made it necessary to update the system, the stator and its winding can be easily dismantled, the stator core is in two concentrically one inside the other , arranged laminated cores, of which only the inner part is the replacement of the The rotor capsule forms, while the outer, removable part carries the stator winding.
Die Zeichnung stellt ein Ausführungsbeispiel des Motors gemäß der Erfindung dar. In einem Deckel 10 ist die Welle 1 für den Motorläufer 2, an die die Welle" des nicht dargestellten Kompressors angeflanscht ist, gelagert. Der Läufer ist in eine Kapsel gasdicht eingeschlossen. Einen TeE dieser Kapsel bildet als lameliierter Hohlzylinder der innere Teil 5 des konzentrisch unterteilten Ständerblechpaketes 13. An" den Ring S schließen sich nach beiden Seiten nicht lameliierte weitere Ringe 6 und 7 aus nicht magnetisierbarem Werkstoff an. Diese beiden Ringe werden zusammen mit dem lamellierteinHohlzylinder 5 in axialer Richtung durch Bolzen 8 zusammengehalten, die gleichzeitig dazu dienen, die Läuferkapsel an dem Deckel 10 zu befestigen. An den äußeren Ring 6 ist 'ein Deckel 3 angesetzt, in dem das Ende der Motorwelle 1 gelagert ist.The drawing shows an embodiment of the engine according to the invention. In a cover 10, the shaft 1 is for the Motor rotor 2 to which the shaft "des not illustrated compressor is flanged, stored. The runner is gas-tight in a capsule locked in. A lamellar hollow cylinder of the capsule forms a TeE of this capsule inner part 5 of the concentrically divided stator core 13. Close the ring S to ″ Further rings 6 and 7 made of non-magnetizable material are not laminated on both sides Material. These two rings are laminated together with the hollow cylinder 5 held together in the axial direction by bolts 8, which also serve to the rotor capsule on the cover 10 to attach. On the outer ring 6 is' a Cover 3 attached, in which the end of the motor shaft 1 is mounted.
Auf den lamellierten Ring 5 des Ständer- 60' blechpaketes ist der übrige Teil 13 des Stän-.derblechpaketes mit den Nuten 14 für die Ständerwicklung 15 abnehmbar aufgesetzt.On the Stand 60 'Laminated Ring 5 sheet core is the remaining part 13 of the stator core with the grooves 14 for the stator winding 15 detachably attached.
