Developed independently by Anhui Voofu Permanent Magnet Technology Co., Ltd., the Voofu Permanent Magnet Governor is an innovative transmission and speed regulation device that transmits torque through air gaps based on Lenz's law of electromagnetism. It is widely used for energy-saving retrofits of high-power motors in power, chemical, metallurgical, cement, coal, iron and steel, national defense and other industries.

Voofu Permanent Magnet Couplings have been widely applied in numerous projects. They are the ideal replacement for torque-limiting fluid couplings in industries such as power, mining, cement and chemical engineering.

Voofu Permanent Magnet Coupling features non-contact magnetic transmission, millisecond-level stall protection, flexible soft start, zero pollution and zero harmonics, 30-year maintenance-free service, and an energy saving rate of 20% to 50%. As a next-generation industrial transmission solution, it is an ideal replacement for torque-limiting fluid couplings and has been widely verified by benchmark enterprises including Conch Cement, Sinopec and Wuhai Chemical.

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.
