一种定子复杂连接异步电机的网络分析方法

Network Analysis Method to Induction Motor with Complexity of Stator Connection

用网络图论对一种定子连接复杂的异步电机进行了分析。以回路电流法为基础 ,选定某一定子绕组为基准绕组 ,列写了用矩阵形式表示的、计算回路电流及支路电流的网络方程。实例的计算结果和试验结果相吻合说明了分析方法的有效性。

By means of network graph theory method,which is different from traditional analytical methods,is presented to analyze the induction motor with complexity of stator connection.A winding through which the forward sequence current and the backward sequenced current are assumed to flow is selected as a reference winding.The network equations based on loop current method and expressed in matrix form are established,and the loop currents,then the brance currents,can be calculated by the equations.The calculated results and tested results for an example machine are in good agreement,which shows the validity of the analysis method.
