摘　　要：首先总结了纯电动汽车驱动用直流电机系统分类及其特点,基于声强技术对其进行了噪声测试分析。对降噪方法进行了初步探讨。The traction motor of EV is differing from the general traction motor completely. The specialty and classify are summarized firstly, the experiment and analysis of direct traction motor system for electric vehicle are study based on the sound intensity. And the ways to decrease noise are discussed at last.

关 键 词：电动汽车 直流电动机 噪声 声强
