汽车用永磁直流电机零件的降噪设计及其分析

Noise reduction Design and analysis of automobile permanent magnet DC motor

随着人们对生活质量要求的不断提高,人们对汽车内部噪声的要求也不断地提高。电机作为汽车众多运动部件(如天窗、电动门玻璃、电动座椅等)的执行元件,对降低汽车内部噪声水平有着直接的影响,为有效降低汽车内部的噪声水平,文章从与产生电机噪声有关的各个零件的设计入手,详细分析产生电机噪声的原因并给出降低电机噪声的设计方法,从而为汽车用电机的设计工程师和质量分析工程师提供切实有效的指导意义。

The requirement of noise in vehicle become more and more critical, because perceived quality become moreimportant factor for vehicle buyer. As a typical actuator for most electrical component (sunroof, window regulator, seats, etc.),noise performance of motor is a direct impact for vehicle sound quality. For improving vehicle noise performance, this paperlist and analysis the design of each parts relate to running noise in detail, then provide effective solution in part design. Theconclusion can be used as guidance for design engineer and quality engineer.
