This magnetic coupling has no gears, no mechanical wear, but suffers from very low torque due to magnetic limitations. However, it enables leak‑proof transmission and automatic overload protection. In this video, we push its performance to the limit: by reducing the air gap, upgrading the flux modulator with silicon steel, and adding N52 magnets, torque is increased from 0.06 N·m to 0.21 N·m. We also explore a planetary‑style magnetic design for even greater force. See how far magnetic transmission can go!
