Basic Design and Operation



Chain Tail permanent magnet 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. CHT provides reliable torque control and generate 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 a torque is established.
Special Features

No mechanical friction, or wear components exist.

Torque is manually adjustable with a knurled adjustment ring.

No additional electrical circuits or external power source.

Torque is established by permanent magnet, the repeatability on ratio of torque to current is very high.

Small size, can be installed horizontally or vertically.
