Abstract
Description
Die Erfindung beschreibt ein Verfahren zur Montage eines bürstenlosen Elektromotors mit einem topfförmigen Gehäuse, einer Statoreinheit, einem Rotor und einer Leiterplatte, wobei die Statoreinheit aus einem mit Kunststoff umspritzten Stator gebildet ist und einen Flansch zum Befestigen des Gehäuses aufweist.The invention relates to a method for mounting a brushless electric motor with a pot-shaped housing, a stator, a rotor and a printed circuit board, wherein the stator is formed of a molded plastic stator and having a flange for securing the housing.
Ein solcher Motor wird beispielsweise als Antriebsmotor für einen Lüfter verwendet. Dabei bewirken das topfförmige Gehäuse und die angeflanschte, spritzgegossene Statoreinheit eine Abdichtung des Motorinneren, wie sie bei vielen Lüftern gefordert ist. Weiterhin ist oft eine Erdung des metallischen Statorkörpers innerhalb der Statoreinheit gefordert.Such a motor is used for example as a drive motor for a fan. The pot-shaped housing and the flanged, injection-molded stator unit cause a seal of the motor interior, as required for many fans. Furthermore, earthing of the metallic stator body within the stator unit is often required.
Durch die abgedichtete Bauweise ist die Montage des Motors jedoch schwierig oder kompliziert. Insbesondere die elektrische Kontaktierung des Stators und/oder der Leiterplatte ist problematisch, da durch das geschlossene Gehäuse von außen keine Montagearbeiten ausgeführt werden können. Dies betrifft insbesondere auch die Erdung.However, the sealed construction makes the installation of the engine difficult or complicated. In particular, the electrical contacting of the stator and / or the circuit board is problematic because no installation work can be performed by the closed housing from the outside. This also applies in particular to grounding.
Aus der
Aufgabe der Erfindung ist es daher, einen Motor der vorgenannten Art zu schaffen, der einfach montierbar ist und der sichere elektrische Verbindungen und eine sichere Erdverbindung aufweist.The object of the invention is therefore to provide a motor of the aforementioned type which is easy to assemble and which has safe electrical connections and a secure ground connection.
Diese Aufgabe wird erfindungsgemäß durch das im Hauptanspruch beschriebene Montageverfahren gelöst.This object is achieved by the mounting method described in the main claim.
Insbesondere die Erdverbindung zwischen Leiterplatte und Gehäuse erfolgt hier über eine Schraube, vorzugsweise eine der Befestigungsschrauben, mit der die Leiterplatte am Gehäuse befestigt wird. Dadurch entsteht kein zusätzlicher Montageaufwand. Die Erdverbindung ist dadurch aber nicht nur sicher, sie kann am offenen Gehäuse auch einfach überprüft werden. Dazu muss lediglich der Widerstand zwischen dem Gehäuse und der Leiterplatte gemessen werden.In particular, the earth connection between the printed circuit board and the housing takes place here via a screw, preferably one of the fastening screws with which the printed circuit board is fastened to the housing. This results in no additional installation effort. But the earth connection is not only safe, it can also be easily checked on the open housing. All you have to do is measure the resistance between the case and the PCB.
Die elektrische Kontaktierung zwischen Stator und Leiterplatte erfolgt auch hier über Steckverbinder, wobei insbesondere ein Steckverbinder eine Erdverbindung zwischen Stator und Leiterplatte herstellt.The electrical contact between the stator and circuit board also takes place here via connectors, in particular, a connector establishes a ground connection between the stator and circuit board.
In einer bevorzugten Ausgestaltung der Erfindung sind als Steckverbindung auf der Unterseite der Leiterplatte Steckbuchsen und an der Statoreinheit entsprechende Stecker-Fahnen angeordnet, die durch passende Öffnungen der Leiterplatte in die Steckbuchsen einsteckbar sind.In a preferred embodiment of the invention are arranged as plug-in connection on the underside of the printed circuit board sockets and on the stator unit corresponding plug flags, which can be inserted through appropriate openings of the circuit board in the sockets.
Die Erfindung ist nachfolgend anhand eines bevorzugten Ausführungsbeispiels mit Bezug auf die beiliegenden Zeichnungen näher erläutert.The invention is explained below with reference to a preferred embodiment with reference to the accompanying drawings.
