Description
Läufer für Doppelgehäuse-Induktionsmotoren mit gemeinsamem Doppelkäfigankera Die Erfindung bezieht sich -auf einen Doppelanker mit gemeinsamen" Käfigwicklung nach Patent 334151, bei welchem beim Anlauf die im Läufer zu vernichtende Energie zum größten Teil in den als Widerstand dienenden Bandagen vernichtet wird. Diese umgeben die beiden Ankern gemeinsam angehörenden Läuferstäbe. Um nun die frei werdende Wärme der Anlaufenergie nach Möglichkeit auf das Läufereisen selbst zu übertragen, wir d®r-Anker# äß der Erfindung ausgeführt. wie beiden kerkörper a sind, wie die Zeiähnung zeigt@-inmler üblichen Weise mit den gemeinsamen Läuferstäben @ 1 "Versehen, welche an den äußeren Stirnfiäcl%n mit den Kurzschlußringen leitend verbunden sind. Außer der Nutenreihe für die gemeinsame Käfigwicklung ist nach der Erfindung noch eine zweite Nutenreihe entweder zwischen den anderen Nuten oder unter diesen vorgesehen, deren Stäbe s je eine Käfigwicklung mit erhöhtem Ohmwert bilden und vorteilhaft unmittelbar mit ihren Enden in den Preßplatten p vernietet sind. Diese Läuferstäbe s lassen sich mit einem beliebig hohen Ohmwert ausrüsten, so daß bei Anlauf dieselbe elektrische Wirkung eintritt wie in dem Anker nach Patent 33q.151..Rotor for double-housing induction motors with a common double cage anchor The invention relates to a double armature with a common cage winding according to patent 334151, in which the energy to be destroyed in the rotor during start-up is mostly destroyed in the bandages serving as resistance. These surround the two anchors that belong together with the rotor bars. To now the one that is becoming free To transfer the heat of the starting energy to the rotor itself, if possible, weather d®r-anchor # carried out according to the invention. how the two bodies are a, like the teeth shows @ -inmler the usual way with the common runner bars @ 1 "provided, which are conductively connected to the short-circuit rings at the outer end faces. Except the row of slots for the common cage winding is another one according to the invention second row of grooves provided either between the other grooves or under them, whose bars s each form a cage winding with an increased ohmic value and are advantageous are riveted directly with their ends in the press plates p. These runner bars s can be equipped with any high ohmic value, so that the same at start-up electrical effect occurs as in the armature according to patent 33q.151 ..
Die Stäbe s, welche wiederum blank durch das Blechpaket führen, ließen sich sogar aus Eisen herstellen. Infolge des Skineffekts würde dann der innere Ohmwert im Augenblick desEinschaltens gegenüber dem bei normaler Umlaufzahl erhöht sein und bei Zunahme der Umdrehungen eine Widerstandsabnahme wie bei dem Anker nach Patent 328162 eintreten. Man könnte auch die Stäbe s so anordnen, daß man bei Anlauf künstlich eine mehr oder weniger große magnetische Streuung und damit die Wirkung erhalten würde, welche von R ü d e n b e r g in der Elektrotechnischen Zeitschrift 19i8, Seite q.83ff., beschrieben worden ist. Es würde sich dadurch ein sanfteres Anlassen der Maschine ermöglichen lassen.The bars s, which in turn lead bare through the laminated core, left can even be made from iron. As a result of the skin effect, the inner ohmic value would then be at the moment it is switched on compared to the normal number of revolutions and as the revolutions increase, there is a decrease in resistance, as in the case of the armature according to the patent Enter 328162. One could also arrange the bars s so that one could artificially run up a more or less large magnetic scattering and thus the effect obtained would, which by Rü d e n b e r g in the electrotechnical journal 19i8, Page q.83ff., Has been described. This would make the starting process smoother allow the machine.
Während der Anlaufperiode des neuen Ankers würden die den beiden Ankerkörpern gemeinsam angehörenden Stäbe l so lange stromlos bleiben, bis die Verdrehung eines der beiden Magnetfelder (vgl. Patent 337108) um 18o° vorgenommen wird.During the start-up period of the new anchor, the two anchor bodies would rods belonging together l remain de-energized until the rotation of a of the two magnetic fields (cf. Patent 337108) is made by 180 °.
