Description
Die Erfindung betrifft einen Außenläufermotor, insbesondere einen Klein- oder Kleinstmotor. Hauptanwendung solcher kleinen Motoren ist derzeit der Antrieb von Lüftern, z. B. zur Kühlung von Prozessoren in Rechnern, oder zur Gerätekühlung in kleinen Regel- oder Steuergeräten. Typische Abmessungen solcher Miniaturlüfter sind 25 × 25 × 8 mm bis 60 × 60 × 25 mm. Ein typisches Gewicht eines solchen Miniaturlüfters liegt etwa zwischen 5 g und 85 g, und die Leistungsaufnahme liegt oft im Bereich von 0,4 W bis 3,5 W. Jedoch sind auch Werte außerhalb der angegebenen bevorzugten Bereiche nicht ausgeschlossen.The Invention relates to an external rotor motor, in particular a small or micro motor. Main application of such small engines is currently the drive of fans, z. B. for cooling Processors in computers, or for device cooling in small control devices. typical Dimensions of such miniature fans are 25 × 25 × 8 mm to 60 × 60 × 25 mm. A typical weight of such a miniature fan is approximately between 5 g and 85 g, and the power consumption is often in the range of 0.4 W to 3.5 W. However, values outside the specified are also preferred Areas not excluded.
Bei Motoren und Lüftern dieser Miniaturgrößen muss die Montage so einfach und sicher wie möglich sein, und man sollte möglichst wenige Einzelteile verwenden, um ein zuverlässiges und preisgünstiges Produkt zu erhalten.at Motors and fans of these miniature sizes must The assembly should be as easy and safe as possible, and you should preferably Use few items to make a reliable and affordable To receive product.
Bei derartigen Motoren/Lüftern für höhere Drehzahlen, z. B. 10.000 bis 15.000 U/min, verwendet man Wälzlager für die Lagerung des Rotors, und diese Wälzlager müssen zur Erzielung eines ruhigen Laufs und einer hohen Lebensdauer in bestimmter Weise montiert werden, wie sie nachfolgend beschrieben wird, was auf möglichst preiswerte Art und Weise geschehen sollte.at such motors / fans for higher speeds, z. B. 10,000 to 15,000 U / min, using rolling bearings for the storage of the rotor, and these bearings have to to achieve a smooth running and a long life in be mounted in a certain way, as described below what's possible cheap way should happen.
Es ist deshalb eine Aufgabe der Erfindung, einen neuen Außenläufermotor, insbesondere einen Klein- oder Kleinstmotor, oder einen Miniaturlüfter, und ein hierfür geeignetes Distanzglied, bereit zu stellen.It is therefore an object of the invention, a new external rotor motor, in particular a small or micro motor, or a miniature fan, and a for this suitable spacer, ready to provide.
Nach der Erfindung wird diese Aufgabe gelöst durch einen Außenläufermotor nach dem Anspruch 1. Bei einem Distanzglied wird diese Aufgabe gelöst durch den Gegenstand des Anspruchs 5.To According to the invention, this object is achieved by an external rotor motor according to claim 1. In a spacer, this problem is solved by the subject matter of claim 5.
Weitere Einzelheiten und vorteilhafte Weiterbildungen der Erfindung ergeben sich aus dem im Folgenden beschriebenen und in der Zeichnung dargestellten, in keiner Weise als Einschränkung der Erfindung zu verstehenden Ausführungsbeispiel, sowie aus den Unteransprüchen. Es zeigt:Further Details and advantageous developments of the invention result from the description below and shown in the drawing, in no way as a limitation The invention to be understood embodiment, and from the Dependent claims.
