    摘要:

    对具有三相不对称交流绕组的感应电动机进行研究，对已有的研究成果进行分析与对比。在对称分量变换下建立了采用序阻抗表达的对称绕组相电压方程，得到了相绕组的自漏阻抗和互漏阻抗与等效阻抗和零序阻抗之间的关系。根据不对称绕组的实际情况，将等效阻抗和零序阻抗分别乘上不同的系数，建立了新的电压方程。采用磁动势分量进行了坐标变换，实现了电压方程的解耦，使计算得到简化。最后，通过实验对计算数据进行了验证。

    Abstract:

    In this paper， an induction motor with asymmetric alternating current windings is studied， and the existing research results are analyzed and compared. For the symmetric winding， under the symmetric component conversion， the voltage equation is expressed by the sequence impedance. For the phase winding， the relationships between the self inductance leakage impedance， the mutual inductance leakage impedance， the equivalent impedance and the zero sequence impedance are obtained. The equivalent impedance and the zero sequence impedance are respectively multiplied by different coefficients according to the actual case of asymmetric winding， so as to establish a new voltage equation. The coordinate conversion of magnetic motive force components is applied to decouple the voltage equation for simple calculation. Finally， the calculation results are verified by experiments.
