Abstract
Elektronisch kommutierter Gleichstrommotor (1) mit einem Axialspalt zwischen einem Rotor und mehreren achsparallel ausgerichteten mit jeweils einem Isolierstoffkörper (15) und einer Statorwicklung (16) versehenen Statorpolen (14) des Gleichstrommotors angeordnet ist, die Statorpole (14) an einen Statorrückschluss (20) anschließen und der, Statorpole (14), Statorwicklungen (16) und den Statorrückschluss (20) enthaltende, Stator (81) in einem Motorgehäuse (50) aus Kunststoffmaterial angeordnet ist, dadurch gekennzeichnet, dass der Stator (81), von einer flexiblen Folie (76), welche als Metallfolie oder als metallisierte Kunststofffolie ausgebildet ist, umgeben ist und zumindest ein großer Teil der Folie (76) innerhalb des Motorgehäuses (50) radial um die Statorwicklungen (16) herum angeordnet ist.Electronically commutated direct current motor (1) having an axial gap between a rotor and a plurality of axially aligned, each with a Isolierstoffkörper (15) and a stator winding (16) provided stator poles (14) of the DC motor is arranged, the stator poles (14) to a stator yoke (20) and the stator (81) containing the stator poles (14), stator windings (16) and the stator yoke (20) is arranged in a motor housing (50) made of plastic material, characterized in that the stator (81) is made of a flexible foil (76), which is formed as a metal foil or as a metallized plastic film, is surrounded and at least a large part of the film (76) within the motor housing (50) radially around the stator windings (16) around.
Description
Die
Erfindung betrifft einen Elektronisch kommutierter Gleichstrommotor
(
Aus
der
Es ist bekannt Elektromotoren mit Metallgehäusen als Abschirmung gegen Störausstrahlungen zu verwenden. Metallgehäuse sind jedoch nachteilig hinsichtlich Geräuschemissionen, insbesondere Körperschallweiterleitung.It is known electric motors with metal housings as a shield to use against interference emissions. metal housing are however disadvantageous with regard to noise emissions, in particular structure-borne sound transmission.
Aufgabe der Erfindung ist es daher eine einfache Möglichkeit zu finden bei einem bestehenden elektronisch kommutierten Gleichstrommotor für eine gute Abschirmung der Störstrahlung zu sorgen, ohne dafür Änderungen an der vorhandenen Konstruktion vornehmen zu müssen, wobei gute Geräuscheigenschaften erreicht werden, eine geringe Lagerhaltung notwendig ist und eine einfache Formgebung und Montage möglich ist.task Therefore, the invention is an easy way to found in an existing electronically commutated DC motor for a good shielding of the interfering radiation too care without making any changes to the existing one To make construction, with good noise properties be achieved, a low storage is necessary and a simple shaping and assembly is possible.
Diese Aufgabe wird erfindungsgemäß durch das Kennzeichen des Anspruchs 1 gelöst. Dadurch, dass eine flexible Folie, welche als Metallfolie oder als metallisierte Kunststofffolie ausgebildet ist, innerhalb des Motorgehäuses radial um die Statorwicklungen herum angeordnet ist, verbessern sich die EMV-Eigenschaften erheblich. Durch Verwendung einer flexiblen Folie erhöht sich das Gewicht des Motors kaum und die Folie ist durch ihre geringe Dicke auch bei bestehenden Motoren nachträglich montierbar. Als Folie eignet sich z. B. eine Kupfer- oder biegsame Aluminiumfolie mit einer Dicke von ca. 0,1 mm oder weniger. Denkbar ist auch ein Geflecht aus einer Mischung von Kunststoff- und Metallfasern.These The object is achieved by the indicator of claim 1. By having a flexible film, which is formed as a metal foil or as a metallized plastic film is, within the motor housing radially around the stator windings arranged around, the EMC properties improve significantly. By using a flexible film that increases The weight of the engine hardly and the film is also due to their small thickness Can be retrofitted to existing engines. As a foil is suitable for. B. with a copper or flexible aluminum foil a thickness of about 0.1 mm or less. Also conceivable is a network from a mixture of plastic and metal fibers.
