The Voofu permanent magnet coupling is essentially a permanent magnet eddy current transmission device, whose operating principle is based on two core physical theories. To put it simply: the motor rotates, the conductor disc cuts magnetic lines of force and generates eddy currents. The magnetic field produced by eddy currents interacts with permanent magnets to drive the load into rotation. The entire process involves no mechanical contact, with power transmitted purely through magnetic fields across an air gap.
