KAISERLICHESIMPERIAL
PATENTAMT.PATENT OFFICE.
Die bis jetzt bekannten Ausführungen von Regelungstransformatoren, bei denen die induzierte Spannung durch Verdrehen eines drehbaren Teiles gegen einen festen Teil geändert wird (sog. Induktionsregler oder Potentialregulatoren), bestehen aus einem Ständer und einem in Lagern beweglichen Läufer (Kern) nach Art derjenigen der Asynchronmotoren. Damit die Genauigkeit der Ausführung nicht allzu groß zu sein braucht, darf der Abstand zwischen Ständer und Läufer bei dieser Anordnung eine bestimmte Größe, meistens 0,5 bis 2 mm, nicht unterschreiten, da sonst bei kleinen Ungenauigkeiten starke einseitige magnetische Züge auftreten. Dieser Luftspalt ist für das Arbeiten des Reglers von Nachteil, da derselbe hohe Magnetisierungsströme verursacht.The previously known designs of control transformers in which the induced Tension changed by twisting a rotatable part against a fixed part (so-called induction regulators or potential regulators) consist of a stand and a rotor (core) that is movable in bearings, similar to that of asynchronous motors. So that the accuracy of the execution does not need to be too great, With this arrangement, the distance between the stator and the rotor may be a certain size, usually 0.5 to 2 mm, do not fall below, otherwise large inaccuracies in the case of small inaccuracies one-sided magnetic pulls occur. This air gap is for the controller to work disadvantage, since it causes high magnetizing currents.
Bei einem nach der Erfindung gebautenIn one built according to the invention
Regler werden diese Übelstände dadurch vermieden, daß der drehbare Teil einen derartigen Durchmesser erhält, daß er ohne besondere Lagerung unmittelbar im Ständer selbst geführt wird.Regulator these inconveniences are avoided in that the rotatable part such Diameter receives that it is performed directly in the stand itself without any special storage.
Durch diese Anordnung kann der Luftspalt bis auf den für die Beweglichkeit nötigen Mindestwert, also auf 0,025 bis 0,1 mm, d. i. auf den zwanzigsten Teil des früher benötigten Abstandes vermindert werden. Einseitiger magnetischer Zug wird dann auch vorhanden sein, er wird aber nur gering sein, da die ihn bedingende Exzentrizität nur gering sein kann.With this arrangement, the air gap can be down to the one necessary for mobility Minimum value, i.e. to 0.025 to 0.1 mm, i.e. i. to the twentieth part of what was previously required Distance can be reduced. One-sided magnetic pull will then also be present, but it will only be slight, since the eccentricity that causes it can only be slight.
Die erwähnten schlechten Eigenschaften des Reglers werden daher stark vermindert; gleichzeitig wird der Regler durch das Wegfallen der Lager einfacher und deshalb billiger. Die Zeichnung zeigt eine derartige Ausführung. The mentioned poor properties of the controller are therefore greatly reduced; simultaneously the controller becomes simpler and therefore cheaper by eliminating the bearings. The drawing shows such an embodiment.
