The first Taiwanese manufacturer of PM Hysteresis Torque Controller

Due to the various applications and high market prices on Permanent Magnet Hysteresis Torque Controller (CHT), Chain Tail has invested resources in this project for years. The product has been successfully developed lately and introduced to the international market.

Chain Tail PM hysteresis units can be configured as a clutch or a brake depending upon mounting. Specifically, it can be used as a “Torque Limiter” for tensioning wire, capping machines and torque-limiting systems. It also provides reliable torque control and generates no wear. Different from friction type of clutches and brakes, the torque is transmitted by magnet flux, which offers superior overload protection for drive units and a safe buffer force when torque is established.
