[0002] Fans are widely used in industries such as steel, metallurgy, and coating. When fans are in use, they need fan brackets to support the operation of the fans. As the basis for the stable operation of the fans, the fan brackets play a vital role in the product. The fan brackets in the prior art are simply welded from a simple panel and a motor base. During the operation of the fan, the fan itself will vibrate due to dynamic balance reasons. This type of simply welded bracket will aggravate this vibration due to its own lack of rigidity, causing relative friction and reducing the life of the product. At the same time, when this type of bracket composed of simple welding is transporting high-temperature media, its bracket cover and panel are prone to deformation, which will cause poor concentricity between the impeller and the motor main shaft and the wind collector, and the impeller and the wind collector are prone to collision, which will then cause the fan vibration to increase, the motor vibration to increase, and seriously affect the life of the motor bearing.
