异步电动机鼠笼条断裂时的定子电流和漏磁

Stator Current and Leakage Flux of an Induction Motor with Broken Rotor Bar and Parallel Stator Windings

根据异步电动机定子电流、气隙磁通及漏磁的频谱,可诊断转子鼠笼条断裂等故障。介绍定子线圈串联和并联时定子电流及漏磁频谱的实测结果。

The cage rotor of an induction motor can be diagnosed by the spectra of the stator current, the air-gap flux, and the leakageflux. However, it is not clear how the connection of stator winding, that is, series or parallel, affects on these spectra.In this letter, we discussthe measured results on spectra of stator current and leakage flux in the both case of parallel and series stator winding.
