»5 speziellen Verwendungszweck entsprechend, gestaltet und zur allgemeinen Verwendung schon allein wegen seines aufwendigen Aufbaues ungeeignet. Aufgabe der Erfindung ist es, ein unter Verwendung eines Minimums von Einzelteilen möglichst einfach herzustellendes und damit billigeres Antriebssystem zu schaffen. Dies wird dadurch erreicht, daß die beiden Weicheisenteile mit ihren benachbarten Enden jeweils ein Polpaar bilden, und das von den Weicheisenteilen und Permanentmagneten gebildete Magnetsystem an einer die Ankerlagerung frei lassenden Stelle von einer einzigen Erregerspule umfaßt wird. »5 Corresponding to special purpose, designed and unsuitable for general use, if only because of its complex structure. The object of the invention is to create a drive system that is as simple as possible to manufacture using a minimum of individual parts and therefore cheaper. This is achieved in that the two soft iron parts with their adjacent ends each form a pair of poles, and the magnet system formed by the soft iron parts and permanent magnets is encompassed by a single excitation coil at a point leaving the armature bearing free.

Die Figur zeigt ein Ausführungsbeispiel der Erfindung.The figure shows an embodiment of the invention.

Der Weicheisenkern des Antriebssystems, der von der Spule Sp umfaßt wird, besteht aus zwei parallel liegenden Weicheisenteilen W in U-Form, die aus zwei Eisenblechen oder aus zweiThe soft iron core of the drive system, which is encompassed by the coil Sp , consists of two parallel soft iron parts W in a U-shape, which consist of two iron sheets or two

gerichtet ist. An Stelle der beiden kleinen Dauermagnete zwischen den beiden Schenkeln der Weicheisenteile kann selbstverständlich auch nur ein einziger Dauermagnet vorgesehen werden, der im Innern der Wechselstromspule zwischen den beiden Weicheisenteilen liegt. Durch die Dauermagnete werden an den Enden der Schenkel der Weicheisenteile zwei Polpaare gebildet, deren Polarität in der Figur durch die Bezeichnung N-S (Nordpol, Südpol) angedeutet ist. Der Anker A ist außerhalb der Spule in der Mitte zwischen den beiden Polpaaren im Schwerpunkt gelagert, so daß sich seine beiden Enden, deren eines beispielsweise mit einem Klöppel K zur Betätigung eines Wechselstromweckers versehen ist, frei zwischen den beiden Polpaaren bewegen können. Das ganze Antriebssystem kann auf den Befestigungswinkeln B befestigt sein. Wird die Spule Sp durch Wechselstrom erregt, so wird durch die eine Halbwelle des Wechselstromes beispielsweise der Nordpol des einen Polpaares geschwächt und dessen Südpol verstärkt, dagegen der Nordpol des anderen Polpaares verstärkt und dessen Südpol geschwächt. Bei der nächsten Halbwelle des Wechselstromes werden die magnetischen Kräfte in den beiden Polpaaren umgekehrt. Die magnetischen Kräfte der beiden Polpaare erzeugen dadurch auf die beiden Ankerhälften stets ein Drehmoment im gleichen Sinn.is directed. Instead of the two small permanent magnets between the two legs of the soft iron parts, only a single permanent magnet can of course be provided, which is located inside the alternating current coil between the two soft iron parts. The permanent magnets form two pole pairs at the ends of the legs of the soft iron parts, the polarity of which is indicated in the figure by the designation NS (north pole, south pole). The armature A is mounted outside the coil in the middle between the two pole pairs in the center of gravity, so that its two ends, one of which is provided, for example, with a clapper K for operating an alternating current alarm clock, can move freely between the two pole pairs. The entire drive system can be attached to the mounting brackets B. If the coil Sp is excited by alternating current, the north pole of one pole pair is weakened and its south pole is strengthened by the half-wave of the alternating current, while the north pole of the other pole pair is strengthened and its south pole is weakened. With the next half-wave of the alternating current, the magnetic forces in the two pole pairs are reversed. The magnetic forces of the two pole pairs thus always generate a torque in the same sense on the two armature halves.
