A double-mover linear motor
By combining the concave bending design with the mid-level damping component, the problem of inconsistent frequency caused by the deformation of the spring sheet in the dual-actuator linear motor is solved, achieving uniform stress distribution and vibration energy dissipation of the elastic component, improving the accuracy of synchronous motion and reducing noise.

AI Technical Summary
Technical Problem
In existing double-acting linear motors, the spring sheet is prone to plastic deformation or fatigue fracture under high-frequency, long-stroke reciprocating motion, resulting in inconsistent frequencies, affecting the accuracy of synchronous motion and control, and generating noise.
Method used
The elastic element adopts a design with concave bending on both sides, combined with a through hole and embedded damping element in the middle layer to disperse stress and dissipate micro-vibrations, ensuring consistent stiffness and frequency matching of the elastic element.
Benefits of technology
It improves the service life of elastic components and the accuracy of synchronous movement, reduces noise and vibration, and enhances the system's impact resistance.
