Description
Transistorgesteuerter Schwingankermotor zum Antrieb von Rasiergeräten Es ist bekannt, elektrische Rasierapparate mit Synchronmotoren mit Schwinganker oder einem rotierenden Anker mit Exzenter anzutreiben, wenn das Messer eine hin- und hergehende Bewegung ausführt, oder einen rotierenden Messerkopf mit irgendeinem kleinen Motor direkt anzutreiben. Es hat sich jedoch bei den verschiedenen Konstruktionen herausgestellt, daß die hin- und hergehende, also schwingende Bewegung des Messers vorteilhafter ist als eine rotierende Bewegung.Transistor-controlled oscillating armature motor for driving shavers It is known, electric shavers with synchronous motors with oscillating armature or to drive a rotating armature with an eccentric if the knife and making reciprocating motion, or a rotating cutter head with any drive small motor directly. However, it has changed with the various constructions revealed that the back and forth, thus swinging movement of the knife is more advantageous than a rotating movement.
Damit diese vorteilhafte Antriebsart auch für einen mit Gleichstrom von geringer Spannung betriebenen Apparat verwendet werden kann, wird ein transistorgesteuerter Schwingankermotor zum Antrieb von Rasiergeräten vorgeschlagen, der nach der Erfindung so ausgebildet ist, daß die Spulen im Emitter und/oder Kollektorkreis und die Rückkopplungsspulen für den Basiskreis direkt auf dem Kein des Schwingantriebes angeordnet sind und daß die Abmessungen des Kerns und der Spulen so gewählt sind, daß die zur mechanischen Schwingungserzeugung erforderliche Oszillatorfrequenz entsteht.So that this advantageous type of drive also for one with direct current Apparatus operated by low voltage can be used, becomes a transistor-controlled one A vibrating armature motor for driving shavers proposed according to the invention is designed so that the coils in the emitter and / or collector circuit and the feedback coils for the base circle are arranged directly on the none of the vibratory drive and that the dimensions of the core and the coils are chosen so that the mechanical Oscillation generation required oscillator frequency arises.
Die Zeichnung zeigt einen Schwingankermotor nach der Erfindung. Auf dem Magnetkem 1 des Motors ist die Antriebswicklung2, eingeschaltet in den Emitter oder Kollektorkreis des Transistors, aufgewickelt. Gleichzeitig ist auf dem Ständereisen 1 eine zweite Wicklung3 als Rückkopplungswicklung für den Basiskreis des Transistors 4 mitaufgebracht. Die Basis wird über einen Kondensator 6 und Widerstände 5 für die Vorspannung an den Rückkopplungskreis angekoppelt. Es entsteht hierdurch eine Schwingschaltung, welche in der Frequenz entsprechend den Kreiskonstanten des Schwingkreises den Antriebsmagneten 1 erregt. Da außerdem praktisch keine Energie außerhalb der eigentlichen Erregung des Schwingankers 9 verlorengehen kann, so ist der Nutzeffekt der Schaltung außerordentlich hoch und daher die Batteriebelastung klein.The drawing shows a vibrating armature motor according to the invention. The drive winding 2, switched on in the emitter or collector circuit of the transistor, is wound on the magnet core 1 of the motor. At the same time, a second winding 3 is applied to the stator iron 1 as a feedback winding for the base circuit of the transistor 4. The base is coupled to the feedback circuit via a capacitor 6 and resistors 5 for the bias voltage. This creates an oscillating circuit which excites the drive magnet 1 in frequency according to the circular constants of the oscillating circuit. In addition, since practically no energy can be lost outside of the actual excitation of the oscillating armature 9 , the efficiency of the circuit is extremely high and therefore the battery load is small.
Es können selbstverständlich auch in vorteilhafter Weiterbildung zwei Antriebsspulen sowie zwei Rückkopplungsspulen sowie zwei Transistoren in Gegentaktschaltung angeordnet sein. Die übliche Konstruktion des Schwingankerantriebs für die Messer kann beibehalten werden. Hierdurch ergeben sich bei Verwendung entsprechender Leistungstransistoren sehr einfache und preiswerte Konstruktionsteile, für eine Massenfertigung geeignet. Der Raumbedarf der Zusammenschaltung ist so gering, daß die bisher üblichen Größen für Rasierapparate völlig ausreichen für den Aufbau des Rasiergerätes selbst und für den Batteriebetrieb sowie für die Wiederladeschaltung. Da das Gerät zum Betrieb keinen Netzanschluß und damit auch keine Netzanschlußschnur erforderlich macht, entfällt auch das lästige Gebundensein bezüglich der Anwendung an einem bestimmten Ort, an dem eine Steckdose zur Verfügung steht. Ein weiterer wesentlicher Vorteil besteht noch darin, daß entsprechend den Anwendungsvorschriften für elektrische Geräte am menschlichen Körper nur Niederspannung im Gerät selbst vorhanden ist.Of course, two can also be used in an advantageous further development Drive coils as well as two feedback coils and two transistors in push-pull circuit be arranged. The usual construction of the oscillating armature drive for the knives can be retained. This results in the use of corresponding power transistors very simple and inexpensive construction parts, suitable for mass production. The space required for the interconnection is so small that the sizes that have been customary up to now for razors completely sufficient for the construction of the shaver itself and for battery operation as well as for the recharging circuit. Because the device to operate does not require a mains connection and therefore also no mains connection cord, There is also no annoying bondage with regard to the application to a specific one Place where an electrical outlet is available. Another major benefit is still that according to the rules of application for electrical Devices on the human body only have low voltage in the device itself.
