电动机噪声理论和控制技术的进展

Development of Motor Noise Theory and Noise Control Technique

首先对电动机噪声理论及控制技术国内外的研究概况作了简要的回顾 ,介绍了这方面新的研究成果 ,然后介绍新的二维电磁噪声理论 ,这是对传统的电磁噪声理论的重要发展。最后针对我国电动机 (基本系列 )在噪声方面存在的突出问题 ,提出了解决问题的途径。

The research background of motor noise theory and noise control technique is briefly reviewed Problems in traditional electromagnetic acoustic noise theory are pointed out,new theory to deal with the electromagnetic noise and the verification by the testing results are introduced The new two dimensional electromagnetic acoustic noise theory enriches the traditional theory The noise problems in domestic motor products are desperate,the paper argues that the ventilation noise component is the key problems and the methods to eliminate the motor noise are theoretically investigated and used in application practices
