Description

Stufenlos regelbarer Asynchron-Kleinmotor Es sind asynchrone Kleinstmotoren mit induktiver und kapazitiver Hilfsphase bekannt, bei denen zur stufenlosen Regulierung der Drehzahl während des Laufes der Läufer in axialer Richtung verschiebbar angeordnet ist.Infinitely variable asynchronous small motor They are asynchronous small motors known with inductive and capacitive auxiliary phase, where for stepless regulation the speed during the run of the rotor arranged displaceably in the axial direction is.

Nach der deutschen Patentschrift 255 209 sind auch Kurzschlußläufermotoren mit einem Spaltrohr und zentrisch aufgesetzten Lagerkappen bekannt, bei denen Jedoch eine stufenlose Drehzahlregulierung während des Laufes ohne zusätzliche Hilfsmittel, z. B. regulierbare Widerstände usw., nicht möglich ist. Die bereits bekannte axiale Verschiebung des Läufers bringt, wenn die austreibende Motorwelle für den Antrieb bei einer Drehzahlregulierung axial unverändert bleiben soll, erheblichen Fertigungsaufwand.According to German patent specification 255 209, squirrel cage motors are also used known with a can and centrally placed bearing caps, in which, however a stepless speed regulation during the run without additional aids, z. B. adjustable resistors, etc., is not possible. The already known axial Displacement of the rotor brings about when the driving motor shaft for the drive should remain axially unchanged with a speed regulation, considerable manufacturing effort.

Erfindungsgemäß werden diese bekannten Nachteile dadurch beseitigt, daß das Spaltrohr so angeordnet ist, daß man dasselbe verdrehen und mittels eines am Statorpaket angeordneten, in einen drallförmigen Schlitz des Spaltrohres eingreifenden Führungsstiftes axial verschieben kann, wobei durch Änderung der Flußrichtung sowie einseitiger Vergrößerung des Luftspaltes eine stufenlose Regulierung der Drehzahl während des Laufes erzielt wird. Eine Lagerkappe oder ein Lagerbügel an der Antriebsseite ist mit dem Stator fest verbunden, so daß der Läufer in seiner Lage zum Stator unverändert bleibt, während das Spaltrohr mit der fest verbundenen Lagerkappe und dem Loslager durch Verdrehen axial verschoben wird.According to the invention, these known disadvantages are eliminated by that the can is arranged so that you twist the same and by means of a arranged on the stator core, engaging in a twist-shaped slot in the can Guide pin can move axially, by changing the flow direction as well one-sided enlargement of the air gap a stepless regulation of the speed is achieved during the run. A bearing cap or a bearing bracket on the drive side is firmly connected to the stator so that the position of the rotor in relation to the stator remains unchanged remains, while the can with the permanently connected bearing cap and the floating bearing is shifted axially by turning.

Abb. 1 zeigt das Schnittbild bei voller Leistung. In dem Stator 1 ist das Spaltrohr 2, das mit Längsschlitzen versehen ist, eingeschoben, wobei die Lagerkappe 3 auf der einen Seite des Spaltrohres festsitzt.Fig. 1 shows the sectional view at full power. In the stator 1 is the can 2, which is provided with longitudinal slots, inserted, wherein the Bearing cap 3 is stuck on one side of the can.

Abb. 2 zeigt das Schnittbild bei Drehzahlregulierung. Die Lagerkappe 4 ist mit dem Stator fest verbunden, während das Spaltrohr 2 mit der Lagerkappe 3a in Pfeilrichtung axial verschiebbar ist. Dadurch wird eine einseitige Luftspaltvergrößerung 5 und damit niedrigere Drehzahl erreicht. Der Läufer 6 verbleibt beim Verschieben des Spaltrohres in seiner ursprünglichen Lage.Fig. 2 shows the sectional view with speed regulation. The bearing cap 4 is firmly connected to the stator, while the can 2 is connected to the bearing cap 3a is axially displaceable in the direction of the arrow. This results in an enlargement of the air gap on one side 5 and thus a lower speed is achieved. The runner 6 remains when moving of the can in its original position.
