Elektromagnet zur Betätigung von Regelungseinrichtungen für Wechsel-oder
Drehstrommotoren.
Diese Erfindung bezieht sich auf Einrichtungen zur Regelung von Wechselstrom-oder Drehstrommotoren mit einem Elektromagneten, dessen Kern bei seiner Bewegung mittels Kontakte die Widerstandsschaltungen bewirkt. Die Einrichtung ermöglicht die Regelung von Wechsel-oder Drehstrommotoren von irgend einer Stelle aus, und zwar nüt Benutzung des Wechselstromes oder Drehstromes selbst.
Die Erfindung liegt in einer eigenartigen Konstruktion dieses Elektromagneten, durch die erreicht wird, dass der auf den Kern ausgeübte Impuls bei noch so langem Hube an allen

zeichnet, dass der Kern mit einer leitenden Umhüllung versehen ist und innerhalb eines Rahmens sich bewegt, der aus mehreren Streifen aus magnetischem Material parallel zum Kern besteht, wobei der Rahmen eine Reihe von übereinanderliegenden Wicklungen trägt. Bei Erregung dieser Wicklungen mittels Drehstromes wird der Kern durch das entstehende Wanderfeld entlang der Streifen bewegt. Die Umhüllung des Kernes kann aus magnetischem oder nichtmagnetischem Material, wie z. B. Kupfer, bestehen.
Die Zeichnung zeigt in Fig. 1 eine Vorderansicht einer Ausführungsform des Elektromagneten mit den Widerstandsschaltungen, in Fig. 2 einen Horizontalschnitt nach der Linie. 2-2 der Fig. l, in Fig. 3 einen Horizontalschnitt nach der Linie 3-3 der Fig. 1, in Fig. 4 einen Kreuzriss des Elektromagneten nach Fig. 1 und Fig. 5 zeigt eine schematische Darstellung der Feldwicklung des Elektromagneten.

Electromagnet for the operation of control devices for change or
Three-phase motors.
This invention relates to devices for regulating alternating current or three-phase current motors with an electromagnet, the core of which, when moved, effects the resistance circuits by means of contacts. The device enables AC or three-phase motors to be controlled from anywhere, using the alternating current or three-phase current itself.
The invention lies in a peculiar construction of this electromagnet, by means of which it is achieved that the impulse exerted on the core is applied to all of them, no matter how long a stroke

shows that the core is provided with a conductive sheath and moves within a frame made up of several strips of magnetic material parallel to the core, the frame supporting a series of superposed windings. When these windings are excited by means of a three-phase current, the core is moved along the strips by the resulting traveling field. The cladding of the core can be made of magnetic or non-magnetic material, such as. B. copper exist.
The drawing shows in Fig. 1 a front view of an embodiment of the electromagnet with the resistance circuits, in Fig. 2 a horizontal section along the line. 2-2 of FIG. 1, in FIG. 3 a horizontal section along the line 3-3 in FIG. 1, in FIG. 4 a cross-sectional view of the electromagnet according to FIG. 1 and FIG. 5 shows a schematic representation of the field winding of the electromagnet.

of the core can be executed accordingly. The brush holder is attached to the guide rod 42 ..
The structural design of the individual parts naturally allows various changes within the scope of the invention.
