By using the generalized Lagrangian-Maxwell equation, the analytic formula of the air gap magnetic field of the generator considering the magnetic saturation is found, and the nonlinear ordinary differential equations of the electromagnetic excited vibration of the generator set are established. It is pointed out that the magnetic saturation characteristics of the generator are One of the causes of multiplicative electromagnetic interference force is obtained. The nonlinear equations satisfy the resonance of the main resonance and the main parameter. The influence of the electromagnetic parameters of the generator set on the resonance characteristics is analyzed. Some new phenomena are revealed
