Abstract: The motion equation of the rotor suspended by active magnetic bearing (AMB)is given in this paper after considering the nonlinear characteristics of the force.Fromthe response equation resulted from this Eq.we gained the functions of the jump ra-nge,and examined the effects of the AMB’s parameters.

Key words: cyclic plastic strain energy, fatigue damage, life prediction, magnetic suspended bearing, jumping range, nonlinear electro-magnetic force
