The nonlinear electron orbit dynamics is presented for a combined electrostatic plasma wave wiggler and an axial guide magnetic field free electron laser near magnetoresonance. The perpendicular orbit equation is derived and simplified identical to the wave-driven nonlinear oscillator equation but with different expressions of parameters. The nonlinear effect induced by the inclusion of [beta][sup 2][sub [perpendicular]] [much lt] [beta][sup 2][sub [parallel]], where [gamma] = (1 [minus] [beta][sup 2][sub [perpendicular]] [minus] [beta][sup 2][sub [parallel]]) [minus] [sup 1/2]. The dependence of the maximum perpendicular wiggling velocity and the orbit excursion on the wiggler constant, the wiggler frequency, and the initial parameters of motion is given analytically.
