摘要
以实际的例子,阐述了分数槽绕组谐波磁势所引起的定子铁心振动,经过认真分析、计算,找到原因并加以处理.介绍了该机定子绕组改接线后降低振动和噪声的结果,可供今后水轮发电机设计借鉴.
Based on the practical examples,this paper expounds the stator core vibration caused by the fractional slot winding MMF harmonics,and finds the reasons and treatment.With careful analysis and calculation,it proves that the modification of the machine stator winding wiring reduced the vibration and noise.The results can be referential for future design of hydroelectric generator.
