AI Technical Summary

Technical Problem

Existing exciter devices have poor anti-interference performance due to their external metal shell structure, making them susceptible to electromagnetic interference, which can lead to signal distortion or decreased stability.

Method used

The device employs a shielded frame structure, which includes a conductive metal layer, a magnetic layer, and a wave-absorbing layer. Combined with features such as locking holes, locking rods, connecting rods, and rolling wheels, it enables the exciter to be detachably mounted and fixed. The combination of the conductive metal layer, the magnetic layer, and the wave-absorbing layer forms a triple shielding state to prevent electromagnetic interference.

Benefits of technology

It effectively prevents the exciter from being subjected to electromagnetic interference during operation, avoids signal distortion and stability degradation, and improves anti-interference capability.
