Abstract

Vibration and noise always occur simultaneously. Vibration is the source of noise. All noises are the transmission of the vibration energy of vibrating body on medium, whether solid or fluid. The noises may through many mediums to our ears and the noises may be very complicated, which are comprised by many vibration sources. However, it is easy to measure the magnitude of the noise. If we hope to reduce the noise, we should research the source of the vibration at first. The frequencies components of the noise can tell me which vibrating body with the maximum vibration. Because the noise component and it’s vibration source have the same frequency. In this section, two motor have been tested. We have recorded the magnitude of the noise. Finally, we carried out spectrum analysis for the test results. Based on the results of motor natural frequencies through finite element analysis, we found, the noise is may caused by the resonance of some parts of the motor when their natural frequency equal to the frequency of the electromagnetic force. We can modify the structure of the motor to reduce the noise.
