降低kV级电机噪声的研究

The study of cutting down the noise of electric machines

提出降低电机噪声的重要性,明确电磁噪声、机械噪声和通风噪声是电机的主要噪声源,应用噪声的迭加与分离理论通过实例分析各噪声源在总噪声中的构成比例,确定影响电机噪声的主要因素为电磁噪声和机械噪声,提出降低噪声的措施及产生的效果。

We raise the importance of cutting down the noise of electric machines. The most of noise origin are machinery ventilation and electromagnetism. We find that there are a lot of sorts noise originl construct proportion by analying and using the theory and noise over lap and separate. The important factor is electromanetism noise and machinery noise.
