In this paper, from the perspectives of the noise of stepping motor in the air conditioner, the frequency and the structure were analyzed for mostly fountainhead noise of structure. The reference point about the motor noise was got. The electromagnetism noise and mechanism noise are the main noises in the motor. There are many the noise-producing sources from mechanism which difficult to check and solve. This paper analyzed the structure and the result of test, and got the method to solve problems.
