Description

Es ist bereits vorgeschlagen worden, zum Antrieb von Sprech- und ähnlichen Maschinen Motoren zu verwenden, die nach Art des sogenannten Ferrarissystems für Drehfeldinstrumente gebaut werden, bei denen für den Kraftliniennuß ein festes Rückschlußeisen vorhanden ist. An den Hauptpolen sind ferner Hilfspole vorgesehen, die von einer kurzgeschlossenen Wicklung bzw. nur einer Windung umschlungenIt has been proposed to power speech and similar machines To use motors that are based on the so-called Ferrari system for rotary field instruments be built in which there is a fixed return iron for the power line nut is. Auxiliary poles are also provided at the main poles, which are short-circuited by a Winding or only one turn wrapped around it

ίο werden.ίο be.

Die von den Hauptpolen ausgehenden Kraftlinien rufen bekanntlich in der rotierenden, vorzugsweise aus Kupfer bestehenden Trommel Wirbelströme hervor, die im Verein mit dem in der kurzgeschlossenen Wicklung bzw. Windung induzierten Strom ein Drehmoment erzeugen. Ein Teil der Kraftlinien geht aber auch durch den von der Kurzschlußwicklung umschlossenen Hilfspol hindurch und erzeugt in der Trommel ein bremsend wirkendes Drehmoment. Dieses letztere kann sich unter Umständen sehr nachteilig auswirken.The lines of force emanating from the main poles are known to call in the rotating, preferably The drum made of copper produces eddy currents in conjunction with that in the short-circuited winding or turn induced current to generate a torque. But some of the lines of force also go through the auxiliary pole enclosed by the short-circuit winding and generated in the drum a braking torque. This latter can be very detrimental under certain circumstances impact.

Dieser Nachteil wird erfindungsgemäß dadurch vermieden, daß an denjenigen Seiten der Hauptpole, an denen die kurzgeschlossene Wicklung bzw. Windung untergebracht ist, aber auch nur an diesen, magnetische Nebenschlüsse vorgesehen werden, welche die schädlichen Kraftlinien so ablenken, daß sie nicht mehr in die Trommel eintreten.This disadvantage is avoided according to the invention in that on those sides of the main poles where the short-circuited winding or turn is accommodated, but only on these, magnetic shunts are provided, which the harmful lines of force distract them so that they no longer enter the drum.

In der Abbildung ist ein Ausführungsbeispiel des Erfindungsgedankens dargestellt. Auf dem feststehenden Teil 1 sind die Wicklungen 2 aufgebracht, die entsprechend der jeweiligen Netzspannung in bekannter Weise wahlweise in Serie oder parallel geschaltet werden können. Ferner sind noch Hilfspole 3 vorgesehen, die von einer kurzgeschlossenen Wicklung bzw. nur einer einzigen Windung 4 umschlungen werden. Die beiden magnetischen Nebenschlüsse sind mit 5 und die vorzugsweise einseitig geschlossene Trommel mit 6 bezeichnet. Zweckmäßig wird die Trommel 6 in bekannter Weise so angeordnet, daß ihr Boden die Schalldose gegen die Einflüsse der Streufelder des Antriebsmotors abschirmt. Mit 7 ist das feste Rückschlußeisen dargestellt. Das Rückschlußeisen 7 kann auch in bekannter Weise unmittelbar auf dem rotierenden Teil, d. h. der Trommel 6, angeordnet werden.In the figure, an embodiment of the inventive concept is shown. On the fixed part 1, the windings 2 are applied, which correspond to the respective mains voltage can be connected in a known manner either in series or in parallel. Further Auxiliary poles 3 are also provided, from a short-circuited winding or only one single turn 4 are wrapped. The two magnetic shunts are marked with 5 and the drum, which is preferably closed on one side, is denoted by 6. Will be expedient the drum 6 arranged in a known manner so that its bottom protects the sound box against the influences shields the stray fields of the drive motor. With 7 the fixed return iron is shown. The back iron 7 can also in a known manner directly on the rotating Part, d. H. the drum 6 are arranged.
