On the basis of equivalent circuit of the inductio n motor, a new analysis method and revolving field method,is presented in the pape r. the proposed method is of universality, it is easy to analyze steady state pe rformance of indution motors having various stator winding connections and set u p tapped single-phase motor as an example,its stator circuit is divided into lo ops and six branches.One branch is selected as reference branch to which the rat or is referred.The positive and negative electromotive forces (EMFS)induced in the all branch windings are regarded as current controlled voltage sources(CCVSs ). by virtue of loop current method used to analyze the electric circuit, the ne twork equations for calculation on the performance of induction motors are estab lished. some current and voltage values of a double-tapped fan motor are given in the paper.A good agreement between calculated results and test results illus trates the validity of the network equations.
