  • Motor suspension for fans, preferably axial-flow fans, as well as method for manufacturing an air grille of such a motor suspension
    Patent number: 9746003
    Abstract: A motor suspension for fans has an air grille with radially extending braces and grille rings that are positioned coaxially to each other and are connected to each other by the radially extending braces. For adapting the motor suspension to a vibration behavior of a fan, at least one of a feature selected from a number of the braces and a diameter of the braces is varied to effect a reduction of acoustic noises and/or natural resonances of the motor suspension. The number of the braces that are preferably made of metal is preferably unequal to the number of vanes of the fan.
