Description

Anlaßschaltungen Gegenstand dieser Erfindung ist die Anwendung der im Patent 327 284 angegebenen Schaltungen für den Anlauf eines einfachen Drehstrommotors mit Kurzschlußanker.Starting Circuits The subject of this invention is the application of the in the patent 327 284 specified circuits for starting a simple three-phase motor with short-circuit anchor.

Nach dem Hauptpatent werden die drei Phasen eines jeden der beiden Gehäuse eines Doppelgehäuseinduktionsmotors mit gemeinsamer Achse und einem gemeinsamen Doppelkäfiganker beim Anlauf über vier Schaltstellungen von der Serienschaltung je zweier korrespondierenden Phasen in die Parallels£haltung gebracht. Hierdurch steigert sich die magnetische Induktion vom halben Normalwert auf den ganzen Normalwert, wodurch das Drehmoment im Verhältnis i zu q. ansteigt. Diese vier Schaltstellungen lassen sich aber auch bei einem Drehstrommotor mit einfachem Kurzschlußanker vorteilhaft anwenden, um Drehmoment und Strom möglichst in kleinen Stufen anwachsen zu lassen. Die drei Phasen eines solchen Motors werden zu diesem Zweck je in zwei Hälften im Gehäuse eingewickelt, so daß diese so entstandenen drei Doppelphasen genau so wie die des Hauptpatents betrachtet werden können.According to the main patent, the three phases of each of the two Housing of a double-housing induction motor with a common axis and a common axis Double cage armature when starting over four switching positions from the series connection two corresponding phases each brought into the parallel attitude. Through this if the magnetic induction increases from half the normal value to the full normal value, whereby the torque in the ratio i to q. increases. These four switch positions but can also be advantageous in a three-phase motor with a simple short-circuit armature apply to allow the torque and current to increase in small steps as possible. For this purpose, the three phases of such a motor are each split into two halves Housing wrapped, so that these resulting three double phases exactly as those of the main patent can be viewed.

Der Vorteil der-Anwendung dieser Anlaufschaltungen gegenüber derjenigen mit einem gewöhnlichen Sterndreieckschalter ist der, daß zunächst die erste Schaltstellung eine noch kleinere Stromaufnahme des Motors bewirkt als wie die der Sternschaltung des Sterndreieckschalters. Dann aber wird der ganze Anlaßvorgang in vier Stufen unterteilt gegenüber zwei beim Sterndreieckschaher, so daß die höchsten Stromspitzen beim Anlauf ganz wesentlich verkleinert werden. Ferner ist hiermit ein weicheres Anlassen des Motors verbunden.The advantage of using these startup circuits over those with an ordinary star-delta switch, that is the first switch position causes an even lower current consumption of the motor than that of the star connection of the star-delta switch. But then the whole tempering process takes place in four stages divided compared to two with the star triangle schaher, so that the highest current peaks can be reduced significantly at startup. Furthermore, this is a softer one Engine starting connected.
