YWFΦ550 External Rotor Motor Axial Cooling Fan

The working principle of the YWFΦ550 external rotor motor axial cooling fan is that when the impeller rotates, the gas enters the impeller axially from the intake vent, and then the energy is pushed by the blade on the impeller, and then flows into the guide vane, the guide vane changes the direction of the deflecting air into axial flow, and at the same time,the gas is introduced into the diffuser tube to further convert the kinetic energy of the gas into pressure energy, and then into the working pipeline. External rotor motor axial cooling fan blades work in a similar way to the wings of an aircraft, but the latter acts lift upward on the wings and supports the weight of the aircraft, while external rotor motor axial cooling fan are positioned and move the air. The cross section of external rotor motor axial cooling fan is generally the wing section, and the blade can be fixed or rotated around its vertical axis. The Angle of the blade to the air flow or the blade spacing can be unadjustable or adjustable. The ability to change the blade Angle or spacing is one of the main advantages of axial flow fans, small blade spacing Angle will produce a lower flow rate, and increase the spacing can produce a higher flow rate.
