摘要
由于变极同步电机气隙磁场中将存在较大的谐波 ,这些磁场谐波对电机运行性能将产生一些影响。本文介绍了单绕组变极同步电机谐波磁场引起的铁心振动和噪声及其计算方法 ,并给出了响洪甸抽水蓄能变极同步发电 /电动机的计算结果。
In the gap magnetic field of pole changing synchronous machine,there would be large harmonics,which have some effects on the operating performance of the machine.This paper introduces the core vibration caused by those harmonic fields.Calculation methods and results are given,taking Xianghongdian pumped storage change pole synchronous gererator/motor as an example.
