车用永磁电机降噪措施与方法研究

Study on Noise Reduction Measures and Methods for Vehicle PM Motors

作为电动汽车重要的驱动源部件,永磁电动的设计、研发一致倍受关注,针对车用永磁电机振动、噪声等核心问题,现将结果工程案例车用永磁电机从振源分析与模态分析两方面研究其振动特性,梳理车用永磁电机减振降噪研究的有效方法。

As an important driving source part,PM motor is consistently focused in design,research and development.In view of the core problems of vehicle PM motor in vibration and noise,this paper takes vehicle PM motor as the resultant engineering project to study its vibration characteristics from two aspects of vibration source analysis and modal analysis,and combs the effective approaches to reduce the vibration and noise of PM motor.
