Description

Von Hand betriebene magnetelektrische Maschine Bei kleinen, von Hand betätigten Wechselstromgeneratoren, insbesondere für Handlampen, Meß- und Signalgeräte, verwendet man für die Erzeugung des Erregerfeldes in der Regel Polräder aus hochmagnetisierbarean Stahl mit Zusatz von Kobalt oder Aluminium und Nickel. Mit solchen Polrädern lassen sich verhältnismäßig starke Magnetfelder erzielen und das Gewicht sowie die Abmessungen der Maschinen klein halten. Um hochwertige Stähle zu sparen und auch bei Verwendung von Polrädern aus gewöhnlichem Stahl Gewicht und Abmessungen des Generators klein halten zu können, wird erfindungsgemäß ein Teil des erforderlichen Erregerfeldes von der induzierten Ankerwicklung erzeugt, indem zu der Nutz- oder zu einer Zusatzwicklung des induzierten Ankers ein Kondensator parallel geschaltet wird. Es ist zwar bekannt, asynchrone Wechselstromgeneratoren mittels Kondensatoren zu erregen, jedoch wird hierbei die ganze Erregerleistung mit Hilfe der Kondensatoren erzeugt. Man hat auch bereits zum Magnetisieren des in einem Generator angeordneten Polrades aus Magnetstahl vorgesehen, die Ankerwicklung in der Weise zu verwenden, daß sie bei laufender Maschine an einen Kondensator angeschlossen wird. Bei dem Generator nach der Erfindung handelt es sich demgegenüber darum, .daß im Betrieb der remanente Magnetismus des Stahlpolra-des den einen Teil und die reduzierte Ankerwicklung den anderen Teil der Erregerleistung liefern soll.Hand-operated magneto-electric machine For small, hand-operated operated alternators, especially for hand lamps, measuring and signaling devices, one uses for the generation of the excitation field usually pole wheels made of highly magnetizable an Steel with the addition of cobalt or aluminum and nickel. Leave with such pole wheels achieve relatively strong magnetic fields and the weight and dimensions keep the machines small. To save high quality steels and also when using them of magnet wheels made of ordinary steel Weight and dimensions of the generator small to be able to hold becomes part of the required excitation field according to the invention generated by the induced armature winding by adding to the useful or an additional winding of the induced armature a capacitor is connected in parallel. It is well known To energize asynchronous alternators by means of capacitors, however, will the entire excitation power is generated with the help of the capacitors. One also has already for magnetizing the magnet wheel arranged in a generator made of magnetic steel provided that the armature winding can be used when the machine is running is connected to a capacitor. The generator according to the invention acts On the other hand, it is a question of the fact that in operation the remanent magnetism of the steel pole one part and the reduced armature winding the other part of the excitation power should deliver.

In Abb. t ist die von dem Polrad ,allein @erzeugte Spannung durch die Kennliniert in Abhängigkeit vom Nutzstrom J dargestellt, die Leistung durch die Kennlinie b. Durch die zusätzliche Erregung mittels Kondensators ergibt sich für die Spannung E die Kennlinie c, für die Leistung L die Linie d. In Abb. 2 ist ein Ausführungsbeispiel der Maschine dargestellt, wie sie bei Taschenlampen Verwendung findet. Zwischen den Polen des lamellierten Ständerblechpaketes e ist das von Hand betätigte Polrad/ drehbar angeordnet. Das Polrad kann aus geschichteten gestanzten Stahlblechen oder auch .aus einem Stück bestehen. Auf dein Anker sind zwei Wicklungen "a, und h angeordnet, von denen die erstere zur Speisung der Glühlampe i -dient. Die Zusatzwicklung h ist an den Kondensator k angeschlossen, sie erzeugt eine höhere Spannung als die Nutzwicklung g, damit ein Kondensator von geringer Kapazität verwendet werden kann. Wenn die Stromerzeugung nur kurzzeitig erfolgt, kann mit Vorteil .ein Elektrolytkondensator Anwendung finden, wobei die Spannung an demselben so gewählt wird, daß sich die günstigste Ausnutzung des Kondensators ergibt. Nutz- und Zusatzwicklung können auch in Hintereinanderschaltung am Kondensator liegen.In Fig. T, the voltage generated by the pole wheel alone @ is through the characteristic curve is shown as a function of the useful current J, the power through the characteristic b. The additional excitation by means of a capacitor results in for the voltage E the characteristic curve c, for the power L the curve d. In Fig. 2 is an embodiment of the machine shown as it is used in flashlights finds. This is done by hand between the poles of the laminated stator core e actuated pole wheel / rotatably arranged. The flywheel can be stamped from layered Sheet steel or also. Consist of one piece. There are two windings on your anchor "a, and h, of which the former is used to feed the incandescent lamp i. The additional winding h is connected to the capacitor k, it generates a higher one Voltage than the useful winding g so a capacitor of small capacity is used can be. If electricity is only generated for a short time, it can be advantageous Electrolytic capacitor find application, the voltage on the same chosen becomes that the most favorable utilization of the capacitor results. Utility and additional winding can also be connected in series on the capacitor.
