摘　　要：作为我国电站（包括核电站）主要出口部件的ＹＫＫ系列电机在国际市场上的竞争力受到噪声指标的影响。本研究结果在不涉及电机的本体结构，不影响电机性能参数的前提下，所采取的降噪措施可使电机的平均噪声级降低１０ｄＢ（Ａ）以上，达到国外同类电机噪声指标的先进水平。并且降噪措施在电机的整个系列上运用能获得同样的降噪效果。The noise index of YKK Series, which are the main export parts to power station (including nuclear power station), is an important competitive factor in international market. The presented work reduces the average noise level of those motors by 10dB(A), without changing its structure and influencing its performance. The results reached the advanced level of the same series in abroad. Moreover, the noise reduction recipe is proved to be efficient for the whole motor series.
