In order to solve the problem of the large moment of inertia of the existing rotating electromagnetic shock absorber for armored vehicles, a new lightweight rotor adaptive electromagnetic shock absorber (LR-AESA) is proposed in this paper. The LR-AESA consists of the left and right symmetrically distributed stators, a rotor in the middle and excitation coils. Secondly, based on the equivalent magnetic circuit method (EMC) and the Ampere loop theorem, and the interaction of the reaction magnetic fields between adjacent eddy current rings and the nonlinear effect of the interaction between the eddy current field and the original magnetic field are further considered, the air gap magnetic field distribution of the LR-AESA of the 10# steel rotor and the copper rotor at different speeds is derived, and the analytical expression of the damping torque is obtained. Finally, the validity of the analytical model was verified by comparison with results from the 3-D finite element method (FEM). The results show that the LR-AESA of the two material rotors can meet the requirements of technical indicators, but in the full speed section (200 ~ 2000 rpm), the copper rotor has the advantage of a wider range of the damping torque adjustment.
