Electromagnetic Compatibility and Interference-Resistant Design of Signal Transmission Cables for Robots

With widespread application of robots in industrial, medical, and service fields, electromagnetic compatibility (EMC) issue of their signal transmission cables has become increasingly prominent. To address the problem, a systematic study on EMC and interference-resistant design of signal transmission cables for robots was conducted in the paper. Electromagnetic interference mechanisms and transmission line theory were analyzed, and comprehensive interference-resistant solutions involving shielding design, grounding strategies, filtering techniques, and wiring optimization were proposed. Simulation and experimental verification demonstrated that employing a double-layer shielding structure could reduce transfer impedance by more than 40%, and optimized wiring strategies could decrease crosstalk by over 30%. Furthermore, the research established an evaluation system for EMC performance of robotic cables, providing theoretical support and a technical basis for the design of highly reliable robotic systems. Finally, combined with research findings, recommendations for industrial applications and future research directions were also presented.
