In order to analyze the starting process, a calculation method of equivalent inductance and resistance parameters of solid rotor synchronous motors is proposed in this paper. Nonlinear harmonic electromagnetic field analysis is used to analyze the field and then the fundamental component of air gap flux density phasor are obtained to calculate the rotor equivalent parameters in dq equivalent circuit. At last, experiments are carried out for the validation of this method.
