| Abstract: | The principles of the generation process of the motors' aerodynamic noise and its frequency characteristics were analyzed and interpreted clearly.Drilling holes on the motor fan's blades and making teeth at the edges of the fan's blades were proposed to reduce this kind of noise.Through a large number of experiments and optimized studies,a satisfied noise reducing effect was obtained. |
