Abstract

Eine Kleinlüfteranordnung hat einen Klein- oder Kleinstlüfter (10) mit einem elektronisch kommutierten Antriebsmotor (21). Der Lüfter (10) hat eine ihm zugeordnete, erste Leiterplatte (52) und ein Lüftergehäuse (30). Auch hat er ein um das Lüftergehäuses (30) herum und mit radialem Abstand von diesem angeordnetes Befestigungsteil (34), und eine Membran (32) aus einem elastischen Werkstoff, welche das Lüftergehäuse (30) mit dem Befestigungsteil (34) verbindet. Im Bereich zwischen Befestigungsteil (34) und Lüftergehäuse (30) ist eine dem Antriebsmotor (21) zugeordnete zweite Leiterplatte (54) befestigt.

A small fan assembly has a small or micro fan (10) with an electronically commutated drive motor (21). The fan (10) has a first printed circuit board (52) assigned to it and a fan housing (30). Also, it has a mounting member (34) disposed around and radially spaced from the fan housing (30), and a diaphragm (32) of resilient material connecting the fan housing (30) to the mounting member (34). In the area between the fastening part (34) and the fan housing (30), a second printed circuit board (54) assigned to the drive motor (21) is fastened.
