Abstract (en)
A suspension system (100) for a fan (10). The suspension system (100) has at least one damping member (20; 22) interposed between a housing (16) housing an impeller (15) of the fan (10), and at least one housing and supporting member (12, 13) housing and supporting an electric motor (11). And the suspension system (100) is characterized in that the damping member (20; 22) is located at a distance (r) according to the following equation: <DF>r = <SQRT>J DIVIDED M</SQRT> </DF> 0 where (M) is the "suspended mass" defined by the combined masses of the electric motor (11), the housing and supporting member (12, 13), a drive shaft (14), and the impeller (15); and (J) is the moment of inertia of the "suspended mass" with respect to a longitudinal axis (a) of symmetry of the drive shaft (14). <IMAGE>
