A Mathematical Model of the Single Phase Multi-speed Capacitor Motor

对于主、副绕组磁势轴线不垂直的电动机电磁计算 ,提出用α、β、O变换和对称分量法相结合的数学分析方法来获得磁势的对称分量 ,进而得出其对应的等值电路和电压平衡方程式及矩阵形式 ,在此基础上则可求解电机的各电磁性能指标。

An α-β-O coordinal shift system remixed with symmetrical component method used for obtaining the symmetrical component of magnetism in regard to the magnetism calculation of non-orthogonal motor for its main or vice winding magnetic shaft is presented in this passage.Then,the equivalvent circuits and calculation of voltage-balancing formula and orthogonal pattern,and based on this,the performance of the magnetism is obtained.
