| 摘 要： | 针对感应电机运行中的噪声问题，通过对一台160 kW潜水感应电机进行多物理场耦合有限元计算，结合解析法对径向电磁力的阶次和频率进行探究，分析了电机气隙中径向电磁力波的时空特性，并通过声学仿真进行了噪声的相关计算。考虑径向电磁力的二维傅里叶分解得到的结果和机壳模型模态的阶次与频率，分析说明了噪声的来源，提出可通过如调整电机机壳散热片数等方式改变电机模态在阶次与频率上的分布或降低机壳振动系数实现噪声控制的目的。

| Abstract: | Aiming at noise problem in the operation of induction motor, through the multi physical field coupling finite element calculation of a 160 kW submersible induction motor, combined with the analytical method to explore the the order and frequency of the radial electromagnetic force, the space-time characteristics of radial electromagnetic force wave in the motor air gap are analyzed, and the correlation calculation of the noise is carried out through acoustic simulation. Considering the results of two-dimensional Fourier decomposition of radial electromagnetic force and the order and frequency of the mode of the shell model, the source of noise is analyzed and explained. The aim of noise control is proposed, such as changing the distribution of motor mode in order and frequency by adjusting the number of radiator ribs of the motor shell or reducing the vibration coefficient of motor shell. |
