电源谐波诱发空调电机噪音问题的研究和控制

The Research and Application of Power Harmonics Induced Air-conditioned Motors Electromagnetic Noise Problem

经研究,电源谐波含量的增加往往会诱发空调器电机噪音,导致用户投诉。通过数据收集和分析,剖析谐波与空调电机噪音的联系,并研究出一种有效控制谐波电源下电机噪音的方法,大幅度降低了空调器售后噪音投诉率。

After study,the power harmonic content will lead to increased motor noise,resulting in user complaints.Through data collection and analysis,analysis of harmonics and noise of motor with air conditioning,and develop a method to effectively control the noise of the motor under harmonic source,greatly reduce the probability of air conditioning aftermarket noise complaints.
