Description
Selbstanlaufender Asynchronmotor, dessen Läufer mit einer Arbeitswicklung und einer Anlaufwicklung versehen ist. Die Erfindung betrifft eine weitere Ausbildung des in dem Hauptpatent 424 497 'geschützten Kurzschlußläufermotors. Wie im Hauptpatent ausgeführt ist, besitzt jener Motor zwei Kurzschlußwicklungen, eine AnI'aufwicklung und eine Arbeitswicklung, von denen die erste am Nutenkopf, die letzte auf dem Nutengrund angeordnet ist. Zwischen beiden Wicklungen sind magnetische, verlagerbare Teile angeordnet, die bei größerer Drehzahl in die U-förmig ausgebildeten. Stäbe der Anlaufwicklung hineingetrieben vzerden.Self-starting asynchronous motor, the rotor with one working winding and a start-up winding is provided. The invention relates to a further development of the squirrel cage motor protected in the main patent 424 497 '. As in the main patent is executed, that motor has two short-circuit windings, one winding and a working winding, of which the first on the groove head, the last on the groove bottom is arranged. There are magnetic, movable parts between the two windings arranged, which formed in the U-shaped at higher speed. Bars of the start-up winding driven into it.
Gegenstand er Erfindung bildet eine Anordnung, die einen allmählichen Übergang vom Anlauf in den normalen Lauf gewährleistet. Zu diesem Zwecke wird eine Anzahl der magnetisch verlagerbaren Teile init stärkeren und eine Anzahl mit schwächeren Federn versehen.The object of the invention is an arrangement that has a gradual Transition from start-up to normal run guaranteed. For this purpose a Number of magnetically displaceable parts with stronger ones and a number with weaker ones Springs provided.
Die Abbildung veranschaulicht die Wirkung einer so ausgeführten Anordnung, sie zeigt die Abhängigkeit des Drehmomentes IM von der Drehzahl n für verschieden ausgeführte Motoren, und zwar stellt a die Charakteristik für einen gewöhnlichen Asynchronmotor dar. b zeigt die entsprechende Kurve für einen nach dem Hauptpatent ,gebauten Kurzschlußläufermotor. Dieser Motor läuft mit einem Drehmoment gleich dem a1/2- fachen des normalen Momentes an. Mit zunehmender Drehzahl nimmt das Moment stark ab, um nach der eigentlichen Anlaufperiode wieder stark zuzunehmen. Diese starken Schwankungen sind bei den Motoren nach vorliegender Erfindung vermieden, wie aus der Kurve c hervorgeht.The figure illustrates the effect of an arrangement designed in this way, it shows the dependence of the torque IM on the speed n for differently designed motors, namely a represents the characteristic for an ordinary asynchronous motor. B shows the corresponding curve for one built according to the main patent Squirrel cage motor. This motor starts with a torque equal to a1 / 2 times the normal torque. The torque decreases sharply with increasing speed, only to increase again sharply after the actual start-up period. These strong fluctuations are avoided in the case of the motors according to the present invention, as can be seen from curve c.
Will man den Anlauf weitgehend herabsetzen, so kann man cie Anlaufwicklung in an sich bekannter Weise als S.tromverdränguigswicklung ausführen.If you want to reduce the start-up to a large extent, you can use the start-up winding run in a manner known per se as S.tromverdränguigswickung.
