Description

Asynchroner Anwurfmotor für Synchronmaschinen Nach dem Hauptpatent werden Anwurfmotoren für Synchronmaschinen (Synchronmotoren, Generatoren, Einankerumformer u. dgl.) mit einer fremderregten Drehstromerregermaschine ausgerüstet. Diese Anordnung gibt die Möglichkeit, die Drehzahl der Synchronmaschine in besonders einfacher Weise mit Hilfe entsprechender Verstärkung der Erregung in der Drehstromerregermaschine auf einen synchronen oder übersynchronen Wert einzustellen und so die Synchronisierung zu bewirken.Asynchronous starter motor for synchronous machines According to the main patent are starting motors for synchronous machines (synchronous motors, generators, single armature converters and the like) equipped with a separately excited three-phase exciter. This arrangement gives the possibility of the speed of the synchronous machine in a particularly simple way with the help of corresponding amplification of the excitation in the three-phase exciter set to a synchronous or oversynchronous value and thus the synchronization to effect.

Gemäß der Erfindung wird diese Anordnung noch ,dadurch vereinfacht, @daß der Anwurfmotor und die Drehstromerregermaschine zu einer einzigen elektrischen Maschine vereinigt sind, wie dies in den neuerdings viel verwendeten kompensierenden Motoren mit eingebauter Erregermaschine der Fall ist. Bei entsprechender Bürstenverstellung können bekanntlich die kompensierten Asynchrommotoren auch eine etwas übersynchrone Drehzahl annehmen. Der kompensierte Asynohronmotor kann eine der bekannten Schaltungen mit einfachem Bürstensatz besitzen. (Heyland-Schaltung mit Speisung des Ständers und besonderer Arbeitswicklung, Schaltung nach Blondel mit Speisung der Läuferwicklung.) Ebenso wie beim Hauptpatent kann man den kompensierten Motor .nach dem Anlauf dazu verwenden, um die der Synchroninaschine (Einankerumformer) zugeführte Wechselspannung zu beeinflussen. Die Zeichnung zeigt an einem Ausführungsbeispiel eine derartige Anordnung. i ist ein Einankerumformer, 2 der ständergespeiste kompensierte Asynchronmotor für den Anwurf. Seine Ständerwicklung 3 ist nach dem Anlauf vor die Wechselstromwicklung des Umformers eingeschaltet. Der Kommutator des kompensierten Motors wird vom Netz aus über einen besonderen Transformator 9 erregt. Durch passende Einstellung dieser Erregung bzw. auch durch Bürstenverschiebung kann in ähnlicher Weise, wie dies bei dem Verfahren gemäß Fig.2 des Hauptpatentes der Fäll ist, die dem Einankerumformer zugeführte Wechselspannung geregelt werden.According to the invention, this arrangement is further simplified in that the starting motor and the three-phase exciter are combined into a single electrical machine, as is the case in the compensating motors with built-in exciter which have recently been widely used. As is well known, with appropriate brush adjustment, the compensated asynchronous motors can also assume a somewhat oversynchronous speed. The compensated asynchronous motor can have one of the known circuits with a simple brush set. (Heyland circuit with supply to the stator and special working winding, Blondel circuit with supply to the rotor winding.) As with the main patent, the compensated motor can be used after start-up to influence the alternating voltage supplied to the synchronous machine (single armature converter). The drawing shows such an arrangement using an exemplary embodiment. i is a single armature converter, 2 the stator-fed, compensated asynchronous motor for starting. Its stator winding 3 is switched on after the start-up in front of the alternating current winding of the converter. The commutator of the compensated motor is excited from the mains via a special transformer 9. By appropriately setting this excitation or also by moving the brush, the AC voltage supplied to the single armature converter can be regulated in a manner similar to that in the case of the method according to FIG. 2 of the main patent.
