| 摘 要： | 电磁振动是电动机的主要噪声源,对于大中型感应电机,主要是通过优化槽配合的方式增加力波阶数同时避开定子铁心相应的模态来减小电机振动噪声。本文提出基于瞬态动力学有限元计算预测感应电机振动的方法,该方法不仅可以定性地为槽配合的优化提供参考,也可以定量地预估出电机的振动噪声量值,为在设计阶段电机振动的优化设计提供方向。并以某大型多相感应推进电机为例验证了该方法的有效性。

| Abstract: | Motor noise is mainly from electromagnetic noise.In order to decrease vibration,the optimized design on slot combination is used,which can increase force order and avoid correspondent vibration modal.On the basis of the transient dynamic element analysis,the method of calculating motor vibration is given in this paper,which can not only conduce to optimize slot combination but also quantitatively evaluate motor vibration.The validity of the method is proved by the large-sized multiphase induction motor analysis and testing results. |
