Axial fan is run by a motor driven axial fans, in fact, are the same for any device cheapest axial fan, you want to work together, there must be a similar "engine." In the choice of axial fan motors Texas axial fans, hoping to be able to drive the impeller motor up to speed quickly and work properly. Motor starting, including start and accelerate the whole process of electricity. Starting its way into full voltage starting and decompression starter. Six proportional to the total noise level of the fan blade speed. According to the analysis, the fan noise source is basically a dipole nature. Further to the introduction of axial fan impeller blade noise is due to the effect on the fan air flow through the veins caused power. Fans may think there are two discrete frequency noise source, a field with the pressure caused by the movement of the rotor blade propeller noise, and the other is powered leaf veins aerodynamic noise caused by interference. Wind maneuver, quiet distance between the blades is an important factor interference noise.
