摘要
对由变频器输出中的高次谐波造成电动机运转噪声增大及载波频率与风机共振造成风机噪声的原因进行了理论分析,提出了解决方案。
The theoretical analysis is made on the reasons why the aggrandizement of motor noise is caused by higher harmonic in the output of frequency converter, and why fan noise is induced by the resonance of carrier wave frequency and fan, and the solution scheme is put forward.
