Abstract

The profiled intermediate piece which corresponds on the one side in terms of the pole pitch to the linear flat motor and on the other side in terms of profile to the shape of the secondary part or of the material being transported improves the utilisation of the shear-force transmission. The improved matching to the machine components and/or to the material being transported is achieved in that the airgap is filled with magnetically conductive materials corresponding to the construction of the motor until a favourable operating size of the airgap is achieved. All casting compounds which correspond to the type of operation can be used as binding means for the magnetically conductive materials.

Description

Beschreibungdescription

Die Erfindung betrifft eine neuartige Ausführung von Linear-Induktions-Motoren zur radialen Anpassung.(Fig. 10 ff) Die Linear-Induktions-Motoren sind im Aufbau und Funktion hinreichend bekannt. Sie werden in Form von Flachmotoren und in Form von sogenannten Tubelarmotoren(Polysolinoid) d.h. Linearmotoren in röhrenförmiger Ausführung, die aus einem kreisförmigen Tnduktor und einem eingebauten zylindrischem Schaft als Anker bestehen,gebaut,(Skinner u. Nachfolger).Es wird auf die Arbeit von Wiart, Theorie u. Anwendung von Linearmotoren verwiesen.The invention relates to a new type of linear induction motor for radial adjustment. (Fig. 10 ff) The linear induction motors are under construction and function sufficiently known. They are in the shape of flat motors and in shape of so-called tubular motors (polysolinoid) i.e. linear motors in tubular Execution consisting of a circular inductor and a built-in cylindrical Shank as anchor exist, built, (Skinner and Successor). It is based on work Referred to by Wiart, Theory and Application of Linear Motors.

Itir den er Fi ndungsgcnliinen Zweck spielen die Flachmotoren eine Knolle. Bei diesen Flachmotoren besteht der ln(luklor aus einem lel(lliv flachen, in der Regel quaderförmigen Körper, der meist llseitig geschlossen ist. Ein solcher Linearmotor verwendet dabei als Anker ein< einfache- ebene- plane Platte oder Schiene nus Stahl-Aluminium oder anderen Kombinationen.For the purpose of the invention, flat motors play a role Tuber. In these flat motors, the ln (luklor consists of a lel (lliv flat, usually cuboid body, which is usually closed on the inside. Such a The linear motor uses a simple, flat plate or as armature Rail made of steel-aluminum or other combinations.

Bei diesen Linearmotoren, die als Flach-Kurz-o. Langstatormotoren Fig. 1-4, oder als Tubelarmotoren Fig. 5-7 gebaut werden, ist die optimale Kraftübertragung nur an symetrisch gleichgestaleten Bauteilen möglich (1.2/2.2/3.2/4.2). Eine Formveränderungführt zur Veränderung der Energieübertragung, die eine Verschlechterung des Leistungsfaktors und des Wirkungsgrades bedeutet.With these linear motors, which are available as flat-short-o. Long stator motors Fig. 1-4, or as tubular motors Fig. 5-7, is the optimal power transmission only possible on symmetrically identical components (1.2 / 2.2 / 3.2 / 4.2). A change in shape leads to change the energy transfer, which leads to a deterioration in the power factor and the efficiency means.

Die bisherige Lösung sah den Bau von Sondermotoren aller Art in angepaßter Form vor. Diese technische Lösung kam in den wenigsten Fällen zur Ausführung.The previous solution saw the construction of special motors of all kinds in adapted Shape before. This technical solution was only implemented in very few cases.

Die vorliegende Erfindung schafft nun die Möglichkeit normale linearmotoren in Flachbauweise für solche Anwendungen einzusetzen und den Mangel der Kraftiibertragung erheblich zu verringern.The present invention now enables normal linear motors to be used in flat construction for such applications and the lack of power transmission to decrease significantly.

I)iese neue technische Konzeption ist einfacher, anwendungsreicher und mit erheblichen Preisvorteilen verbunden,sowoh bei der Erstellung, als auch im Betrieb solcher Anlagen.I) his new technical conception is simpler and more applicable and associated with considerable price advantages, both in terms of creation and as well in the operation of such systems.

Die Ankerplatte ist eine baulich festvorgegebene Form, die vom Maschinen-Anlagenteil bedingt wird. Der Linearmotor ist ebenfalls in einer baulich festvorgegebener Form als "normale" Ausführung konstruktiv festgelegt.The anchor plate is a structurally fixed form that is used by the machine system part is conditioned. The linear motor is also in a structurally predetermined form as "normal" design specified.

Die Skizzen zeigen die Ausführungsformen:l bis 7 Die neue erfindungsgemäße Anpassung erfolgt in der Form, daß der Luftspalt entsprechend der motormäßigen Bauform mit längs/ oder quer lamelierten Bauteilen polschrittmäßig bestückt wird.The sketches show the embodiments: 1 to 7 The new invention Adaptation takes place in such a way that the air gap corresponds to the design of the motor is equipped with longitudinally / or transversely laminated components in a pole-step manner.

(Fig. 10 und ff) Die "Zwischenlamelierung" zwischen den Maschinen- oder Schienenbauteilen kann auch ausgeführt werden mit magnetisch leitendem Pulver oder kompakten Eisenspänen, die ebenfalls den Luftspalt verringern und den Kraftschluß vergrößern.(Fig. 10 and ff) The "intermediate lamination" between the machine or rail components can also be made with magnetically conductive powder or compact iron filings, which also reduce the air gap and the frictional connection enlarge.
