摘要
采用分析电磁噪声的频谱特性与有限元法分析定子铁心固有振动频率相结合的方法,对变频电机产生高频电磁噪声的原因进行分析,并提出了一系列的改进措施。经过样机试制、振动及噪声试验,证明改进措施达到了改善电磁噪声的预期目标。
Combining spectrum characteristics of electromagnetic noise with NSYS analysis of stator core inherent vibration frequency, reason for high-frequency electromagnetic noise of variable frequency motor was analyzed, and a series of measures to improve were proposed. By a trial production, vibration and noise test, the measures reached the electromagnetic noise＇s target.
