Description

Die Erfindung betrifft eine elektrische Maschine mit eingebautem Kondensator.The invention relates to an electrical machine with a built-in capacitor.

Es sind bereits elektrische Maschinen mit eingebauten Kondensatoren bekanntgeworden;. Die Kondensatoren sind hierbei meist zusätzliche Teile der elektrischen Maschine, für die in der Regel wenig Räumvorhanden ist und die, auch wenn sie nur wenig Raum in Anspruch nehmen, stets als störend empfunden werden. Die Hinzufügung eines Kondensators zu einer elektrischen Maschine bedeutet dabei eine Vergrößerung der normalen Type einer elektrischen Maschine ohne Kondensator. Man kann daher eine elektrische Maschine mit Kondensator meist nicht in dem gleichen Raum unterbringen wie eine normale Maschine ohne Kondensator.There are already electrical machines with built-in capacitors known;. The capacitors are mostly additional parts of the electrical system Machine for which there is usually little clearance and which, even if only it take up little space, always be perceived as annoying. The addition of a capacitor to an electrical machine means an enlargement the normal type of electrical machine without a capacitor. One can therefore use a Do not usually place electrical machines with capacitors in the same room like a normal machine without a capacitor.

Es sind bereits elektrische Maschinen bekanntgeworden, die diese Übelstände vermeiden,. indem die Kondensatoren durch die voneinander isolierten Bleche des Blechpaketes selbst gebildet werden. Gemäß der Erfindung werden derartige elektrische Maschinen dadurch wesentlich verbessert; daß das Blechpaket aus viereckigen Blechen gebildet wird, die, z. B. um q.5°, gegeneinander versetzt aufeinanderliegen, so daß die Kondensatoranschlüsse in gehörigem Abstand voneinander verlaufen. Die Bleche eines Blechpaketes bilden hierbei zweckmäßig abwechselnd die Bleche je eines Kondensators, und ein Blech über das andere ist miteinander elektrisch leitend verbunden. Die Bleche des -Blechpaketes sind hierbei vorteilhaft für die entsprechende Kondensatorspannung isoliert. Man überzieht zweckmäßig die Bleche des Blechpaketes mit Aluminium und isoliert sie durch eine Aluminiumoxydschicht voneinander. Die Blechpakete sind vorteilhaft gegenüber Erde, dem Gestell, dem Gehäuse, dem Mantel und gegenüber anderen Halteteilen mit Hilfe von Nieten oder Klammern voneinander isoliert und zusammengepreßt. Die neue elektrische Maschine gestattet auf einfachste Weise die Anwendung des Kondensators zur Phasenverschiebung oder zur Entstörung. Der Kondensator liegt vorteilhaft am gleichen Netz wie die das Blechpaket erregende Induktionsspule des Blechpaketes. Die magnetischen Bleche sind zweckmäßig durch sehr dünne, mit Aluminiumoxyd überzogene Aluminiumbleche voneinander getrennt. Die Aluminiumbleche kann man' leitend miteinander verbinden, so daß sie einen Pol des Kondensators bilden, während das magnetische Blechpaket den anderen Pol bzw. die Erdung des Kondensators darstellt: In der Zeichnung ist ein Ausführungsbeispiel dargestellt.Electrical machines have already become known to have these inconveniences avoid,. by the capacitors through the insulated metal sheets of the Laminated core itself are formed. According to the invention, such electrical Machines significantly improved as a result; that the laminated core consists of square metal sheets is formed, which, for. B. by q.5 °, offset against each other, so that the capacitor connections run at an appropriate distance from one another. The sheets of a laminated core expediently alternate between the laminations of a capacitor, and one sheet metal over the other is connected to one another in an electrically conductive manner. the Sheets of the sheet stack are advantageous for the corresponding capacitor voltage isolated. It is useful to cover the sheets of the laminated core with aluminum and isolates them from each other with a layer of aluminum oxide. The sheet metal stacks are advantageous with respect to the earth, the frame, the housing, the jacket and with respect to other holding parts isolated from one another and pressed together with the aid of rivets or clamps. the The new electrical machine allows the capacitor to be used in the simplest possible way for phase shifting or for interference suppression. The capacitor is advantageously on same network as the induction coil of the laminated core that excites the laminated core. The magnetic sheets are expedient by very thin, coated with aluminum oxide Aluminum sheets separated from each other. The aluminum sheets can be 'conductively connected to each other connect so that they form one pole of the capacitor, while the magnetic Laminated core represents the other pole or the grounding of the capacitor: In the drawing an embodiment is shown.

Fig. i zeigt eine Draufsicht und Fig. 2 eine Seitenansicht auf ein schematisch dargestelltes Blechpaket.FIG. 1 shows a plan view and FIG. 2 shows a side view of a schematically shown laminated core.

Das Blechpaket i besteht aus den Blechen 2 und 3, die so aufeinanderliegen, daß bei q. die einen Bleche und bei 5 die anderen Bleche angeschlossen werden können. Wie man aus der Zeichnung ersieht, sind die Bleche des Blechpaketes ein ums andere elektrisch leitend miteinander verbunden, und die zusammengehörenden miteinander elektrisch verbundenen Bleche bilden jeweils einen Teil eines Kondensators. Die Bleche sind, wie bereits oben erwähnt, sämtlich voneinander isoliert.The sheet package i consists of sheets 2 and 3, which lie on top of one another, that at q. one sheet and at 5 the other sheets can be connected. As you can see from the drawing, the sheets of the laminated core are one after the other electrically connected to one another, and the belonging together electrically connected sheets each form part of a capacitor. the As already mentioned above, metal sheets are all insulated from one another.

Auf- diese Weise erhält man aus den an sich vorhandenen Blechpaketen von Motoren, Generatoren, Transformatoren usw: ohne Erhöhung des Raumbedarfs auf billigstem Wege Plattenkondensatoren, die zum Störschutz, zum Anlauf (von Einphasenmaschinen), zur Cosinusverbesserung von elektrischen Apparaten usw. verwendet werden können.In this way, one obtains from the sheet metal stacks that are actually present of motors, generators, transformers etc: without increasing the space requirement cheapest way plate capacitors, which are used for interference protection, for starting (of single-phase machines), can be used for cosine enhancement of electrical apparatus, etc.
