Description
AsynchronmaschinenAsynchronous machines
Zur Kühlung freiliegender Kommutatoren von Kommutatormaschinen verwendete man bisher Luft, die ebenfalls durch. Lüfter erzeugt wurde, die den Innenteil der Kornmutatormaschine kühlten. Die Führung dieser Kühlluft zum Kommutator und über diesen hinweg erforderte jedoch besondere, zum Teil recht umständliche Vorrichtungen. Die Erfindung gibt.nun eine für besondere FaEe wesentlich einfachere Einrichtung zum Kühlen freiliegender Kommutatoren. Sie betrifft einen besonderen Maschinensatz, nämlich einen solchen, bei dem ein Hilfsmotor für den Antrieb der Kommutatormaschine vorgesehen ist, der auf der Kommutatorseite dieser Maschine angeordnet ist. Nach der Erfindung soll ein Hilfsmotor mit äußerer Mantelkühlung verwendet werden und diese Kühlung auch zur Kühlung des Kommutators herangezogen werden. DerOne used to cool exposed commutators of commutator machines so far air that is also through. Fan was created which was the inner part of the grain mutator machine chilled. The routing of this cooling air to the commutator and over it, however, required special, sometimes quite right cumbersome fixtures. The invention now gives one essential feature for special cases simpler facility for cooling exposed commutators. It concerns a special one Machine set, namely one in which an auxiliary motor for driving the Commutator machine is provided, which is arranged on the commutator side of this machine is. According to the invention, an auxiliary motor with external jacket cooling is to be used and this cooling also for cooling of the commutator can be used. Of the
ao die Mantelfläche des Hilfsmotors bestreichende ICühlluftstrom soll auch noch den Kommutator der Kommutatormaschine bestreichen.ao the outer surface of the auxiliary motor brushing the cooling air flow should also the commutator the commutator machine.
Es ist an sich bekannt, Apparate zugleich durch einen Luftstrom kühlen zu lassen, der das Innere von Maschinen bestreicht; doch sind diese Apparate in die Maschinen 'eingebaut, so daß sie sozusagen einen Bestandteil der Maschine bilden und ihre Kühlung durch den das Innere der betreffenden Maschine bestreichenden Luftstrom naheliegend ist, während im vorliegenden Fall durch den eine Maschine kühlenden Luftstrom ein Teil einer zweiten Maschine gekühlt wird, die selbst Kühlmittel besitzt, die das Innere der Maschine kühlen und die bisher unbedenklich, auch zur Kühlung dieses Teiles herangezogen wurden.It is known per se to allow apparatus to be cooled by an air stream at the same time, which paints the inside of machines; but these devices are built into the machines, so that they form a part of the machine, so to speak, and their cooling through the airflow sweeping the interior of the machine in question is obvious, while In the present case, part of a second machine is cooled by the air flow cooling one machine, which itself Has coolants that cool the inside of the machine and which were previously harmless, were also used to cool this part.
Durch die Erfindung wird also ohne Anordnung besonderer umständlicher Hilfsmittel eine recht wirksame Kühlung der Kommutatoroberfläche erreicht. Es ist dabei zweckmäßig, den Durchmesser des Kommutators annähernd gleich dem des äußeren Mantels des Antriebsmotors zu machen, so daß der Kühlluftstrom, wenn er den Kommutator erreicht, keine Umlenkung erfährt bzw. möglichst nahe an die Kommutatorfiäche herangelangt. The invention thus eliminates the need for special cumbersome aids quite effective cooling of the commutator surface achieved. It is useful here to have the diameter of the commutator approximately equal to that of the outer jacket of the drive motor so that the cooling air flow, when it reaches the commutator, experiences no deflection or comes as close as possible to the commutator surface.
Die Zeichnung veranschaulicht die neue Anordnung an einem Beispiel. 1 ist ein eigenerregter Phasenschieber für eine Asynchronmaschine, 2 der Antriebsmotor. Der Antriebsmotor besitzt eine äußere Mantelkühlung mit Hilfe des Ventilators 3.The drawing illustrates the new arrangement using an example. 1 is a self-excited Phase shifter for an asynchronous machine, 2 the drive motor. The drive motor has an outer jacket cooling with the help of the fan 3.
