Description
Die Erfindung betrifft eine geschlossene elektrische Maschine, bei der wenigstens ein Stirnraum, durch eine umlaufende, vorzugsweise mit Flügeln oder Rippen versehene Scheibe abgedeckt ist, und hat die Aufgabe, die in dem Maschineninnern !entstehende Wärme durch diese Abdeckscheibe hindurch nach außen abzuführen.The invention relates to a closed electrical machine in which at least one Frontal space, by a circumferential, preferably provided with wings or ribs Disc is covered, and has the task of creating inside the machine! Dissipate heat to the outside through this cover plate.
Erfindungsgemäß ist die umlaufende Wicklung wärmeleitend mit der Abdeckscheibe verbunden.According to the invention, the circumferential winding is thermally conductive with the cover plate tied together.
Besondere Vorteile bietet die Erfindung für Käfigläufer. Hier bildet 'erfindungsgemäß der Stirnring des Käfigs wenigstens einen Teil der Abdeckscheibe. Er wird zu diesem Zweck scheibenartig verbreitert und in an sich bekannter Weise mit Lüfterflügeln versehen.The invention offers particular advantages for squirrel cage rotors. Here forms' according to the invention the end ring of the cage at least part of the cover plate. For this purpose it is widened like a disk and provided in a known manner with fan blades.
Zwei Ausführungsformen des Erfindungsgegenstandes sind in der Zeichnung im Axialschnitt beispielsweise dargestellt.Two embodiments of the subject matter of the invention are shown in the drawing Axial section shown for example.
In dem Maschinengehäuse 1 (Fig. 1) ist bei 2 und 3 die Welle 4 des Käfigläufers 5 gelagert. Auf der Antriebsseite beim Lager 2 ist das Maschinengehäuse abgekapselt, der Schild des Lagers 3 hat Lufteintrittsöffnungen 30 und Luftaustrittsöffnungen 31. Auf dieser Seite ist der Maschinenstirnraum durch den scheibenartig verbreiterten Stirnring 6 des Käfigläufers abgedeckt. Der Stirnring ist mit Lüfterflügeln 7 versehen, die durch die Öffnung 30 Luft einsaugen und durch die Öffnung 31 Luft ausblasen. Auf diese Weise wird die in der Käfigwicklung entwickelte Wärme nach außen durch die Abdeckscheibe 6 hindurchgeführt.In the machine housing 1 (Fig. 1) is at 2 and 3, the shaft 4 of the squirrel cage rotor 5 is supported. On the drive side by bearing 2 If the machine housing is encapsulated, the shield of the bearing 3 has air inlet openings 30 and air outlet openings 31. On this side the machine front space is through the disc-like widened end ring 6 of the squirrel cage is covered. The forehead ring is with Fan blades 7 are provided, which draw in air through the opening 30 and through the opening 31 Blow out air. In this way, the one in the cage winding is developed Heat passed to the outside through the cover 6.
Während in Fig. 1 der Ständer feststeht und der Läufer sich dreht, sind in Fig. 2 die Verhältnisse umgekehrt. Hier läuft der Ständer mit dem Gehäuse um, das auf der einen Seite 9 als Kupplung ausgebildet ist. Die Welle 4 ist in einem Vierkant 40 festgehalten. Auch hier ist der Stirnring 6 verbreitert und mit Flügeln 7 versehen. An den Stirnring ist eine beispielsweise aus Isoliermaterial bestehende Scheibe 8 angesetzt, die den Stirnraum zwischen dem inneren Umfang des Ringes und der feststehenden Welle abschließt. While in Fig. 1 the stator is stationary and the rotor rotates, in Fig. 2 are the Conditions reversed. Here the stand with the housing revolves, which is on one side Page 9 is designed as a coupling. The shaft 4 is held in place in a square 40. Here, too, the end ring 6 is widened and provided with wings 7. To the head ring is a disk 8 made of insulating material, for example, is attached to the end space between the inner circumference of the ring and the fixed shaft.
In Fig. ι ist der äußere Durchmesser des Stirnringes 6 größer als der Durchmesser des Maschinenluftspaltes, in Fig. 2 kann der innere Durchmesser des Ringes 6 kleiner gemacht werden als der Durchmesser des Luftspaltes. In Fig. Ι the outer diameter of the end ring 6 is greater than the diameter of the Machine air gap, in Fig. 2, the inner diameter of the ring 6 can be made smaller are called the diameter of the air gap.
Derartige Motoren kommen hauptsächlich für Reversierbetriebe in Betracht und für Betriebe, bei denen der Motor häufig angelassen wird. Beispielsweise kann der Motor mit Vorteil für Rollgangsantriebe, für Walzwerke o. dgl. benutzt werden.Such motors are mainly used for reversing operations and for Businesses where the engine is started frequently. For example, the motor can be used with advantage for roller table drives, for Rolling mills or the like can be used.
