摘要

如果对称三相异步电机由不对称电压系统供电，则电磁状态变得不对称，机械输出也受到影响。电流和通量表不再是圆形的，而是椭圆形的。主要量的不对称系数取决于电源电压的不对称系数;此外，它还依赖于运动操作。一旦确定了定子电流和主磁通是如何受到影响的，研究定子主磁通就顺理成章了。本文研究了不对称供电对定子磁链的影响。该方法是在分析研究的基础上提出的，仿真结果得到了验证。

On the Stator Flux of an Induction Machine Asymmetrical Supplied

If a symmetrical three-phase asynchronous machine is powered by an asymmetrical voltage system, the electromagnetic regime becomes asymmetric, and mechanical outputs are influenced as well. The currents and fluxes hodograph is no longer circular but elliptical. The dissymmetry factor of the main quantities depends on the supply voltage dissymmetry factor; in addition it get dependent on the motor operation. Once determined how stator currents and main flux are influenced, studying the stator main flux comes naturally. This paper is a study on how asymmetrical supply influences the stator flux. The approach is based on analytical study and the results have been confirmed by simulation.
