Abstract
Description
Die Erfindung betrifft einen kollektorlosen Außenläufermotor.The The invention relates to a brushless external rotor motor.
Derartige Motoren haben einen permanentmagnetischen Rotor, also einen Rotor, oft mit einem magnetischen Rückschluss, an welchem Dauermagnete angeordnet sind, die z.B. als Keramikmagnete, oder als Kunststoffteile mit eingebetteten hartferritischen Elementen, ausgebildet sein können.such Motors have a permanent magnetic rotor, ie a rotor, often with a magnetic inference, on which permanent magnets are arranged, e.g. as ceramic magnets, or as plastic parts with embedded hard ferrite elements, can be trained.
Derartige Rotoren müssen ausgewuchtet werden, um einen ruhigen Lauf zu erreichen, und es ist bekannt, im Kunststoffteil solcher Rotoren hierfür besondere Taschen vorzusehen, in welche zum Zwecke des Auswuchtens kleine Metallteile eingepresst werden, die ein passendes Gewicht haben.such Rotors must be balanced to achieve a smooth running, and it is known to provide special pockets in the plastic part of such rotors for this purpose, in which for the purpose of balancing small metal parts are pressed, that have a suitable weight.
Es ist deshalb eine Aufgabe der Erfindung, einen neuen kollektorlosen Außenläufermotor bereit zu stellen.It is therefore an object of the invention, a new brushless External rotor motor to provide.
Nach der Erfindung wird diese Aufgabe gelöst durch den Gegenstand des Anspruchs 1. Auf diese Weise erhält man eine hohe Wuchtgüte, und die Geräusche eines derartigen Rotors werden optimiert, da er – anders als die bekannten Rotoren – keine Öffnungen oder Kerben zum Einsetzen von Metallteilen hat, welche bei der Drehung des Rotors Geräusche verursachen könnten. Vielmehr sind geeignete Miniaturkörper, z.B. Miniaturkugeln, entweder voll oder zumindest teilweise in der Außenoberfläche des Rotors angeordnet und bilden Erhebungen an dieser aus. Durch diese Erhebungen ist die Außenoberfläche strömungsgünstig ausgestaltet.To the invention, this object is achieved by the subject of the Claim 1. In this way receives you have a high balancing quality, and the sounds Such a rotor are optimized because it - unlike the known Rotors - no openings or has notches for insertion of metal parts, which during rotation of the rotor cause noises could. Rather, suitable miniature bodies, e.g. Miniature balls, either fully or at least partially disposed in the outer surface of the rotor and make surveys on this. Through these surveys is the Outer surface designed streamlined.
Weitere Einzelheiten und vorteilhafte Weiterbildungen der Erfindung ergeben sich aus den im Folgenden beschriebenen und in der Zeichnung dargestellten, in keiner Weise als Einschränkung der Erfindung zu verstehenden Ausführungsbeispielen, sowie aus den Unteransprüchen. Es zeigt:Further Details and advantageous developments of the invention result from those described below and shown in the drawing, in no way as a limitation the invention to be understood embodiments, and from the dependent claims. It shows:
