摘要
介绍了电机噪声频谱分析的一些基本知识,并选择一台装配有角接触轴承的电机进行噪声频谱分析,根据测试结果判断电机产生振动噪声的原因并提出可行的改进措施。
Some basic knowledge of frequency spec-trum analysis on motor noise was introduced and a motor with angular contact bearing was selected to carry on frequency spectrum analysis. The cause for the motor to produce noise was judged and improved measures were pre-sented base upon the test result.
