In order to meet the needs of the battlefield, a double-sided moving armature permanent magnet linear ejection motor with high maneuverability is proposed. The structure of the permanent magnet linear ejection motor with moving armature is optimized. By designing the self-alignment guide structure, the air gap can automatically tend to be symmetrical and the normal force caused by the asymmetry of the actuator can be weakened. The eddy current resistance in the process of launch can be effectively reduced by replacing supporting frame materials and applying stiffeners. In addition, the braking effect of the brake segment can be improved and the impact force can be reduced by changing the brake structure to hydraulic damping brake.
