Wire and Cable Applications

How to build precise unwinding/rewinding systems using simple, easy to use technology. Magnetic particle brakes can provide an adjustable braking tension for unwinding film, wire or any web.  Magnetic particle clutches can provide an adjustable tension for rewinding the same.  Simple, effective tensioning systems can easily be built when each are teamed with a D.C.…

Precision tension control is needed for many types of packaging or labeling machinery. Stretch-wrap machines wrap thin plastic around boxes stacked tall on a pallet, to keep the boxes secure and prevent movement during shipping. Automatic machines also apply plastic labels or film from a large supply roll onto drink containers or other food and…

Hysteresis Brakes

Hysteresis Brakes: Torque Without Physical Contact The coil produces a magnetic field while the primary pole structure directs and concentrates the magnetic field. The rotating hysteresis drag cup is connected to the output shaft which is supported by ball bearings. The primary pole structure produces alternating polarity tangentially magnetizing sections in the drag cup. As the…

Magnetic Particle Brakes - collage

Magnetic particle and hysteresis type brakes & clutches are used for precision torque & tension control. Brakes – When energized, the shaft becomes coupled to the brake’s housing. Typical applications:  Brakes can provide adjustable torque for unwinding (payout) of webs, such as wire, foil & paper.  Another popular application: Brakes can provide adjustable torque loads…
