By virtue of graph theory,the network equations based on the loop current method are set up for single-phase induction motors. This network method is suitable for analysis and calcul-ation of the single-phase induction motor having any stator winding connection. Bacause the main formulas are expressed by matrixes, it is also convenient for computer programming. Taking a capacitor single-phase motor for example, some performance indexes of the motor are calculated by the proposed analysis method. The good agreement between the calculated results and the experimental ones shows the validity of this method.
