针对永磁同步电机振动及噪声的问题,从电机定子系统的结构模态入手,通过仿真分析不同铁心模型及不同机壳厚度对定子系统的影响,分析定子各参数对电机振动及噪声的影响。通过试验验证了仿真求解的可靠性,得到各参数对定子系统振型影响的一般规律。

Aiming at the problem of vibration and noise of permanent magnet synchronous motor, starting from the structural modality of the motor stator system, the influence of stator parameters on motor vibration and noise was analyzed through the simulation of the influence of different iron core models and different shell thicknesses on the stator system. The reliability of the simulation was verified by experiments. Finally, the general law of the influence of various parameters on the vibration mode of stator system was obtained.
