A nonlinear finite element method has been completed of one induction machines for the analysis of electromagnetic field in this paper. The focus is to build a circuit model of the end of the stator winding and rotor ring and achieve the coupled calculation of the finite element and the end circuit of machine taking into account the nonlinear in the core material. This method implements the loading of the voltage of the stator winding and considers the influence of the entire machine electromagnetic field caused by the end resistance and leakage inductance. Compared to the traditional analysis method, we can reduce the dependency of experience design. It can also be used for analysis and optimization of the new machine.
