Hysteresis Tensioning Brakes

Tensioning Brakes are a simple way to provide controlled tension during a wide variety of spooling, winding, wrapping, tightening and machining operations. Rugged and durable, Tensioning Brakes provide constant torque unaffected by rotation speed. A variety of mounting options and bolting configurations are available for Original Equipment Manufacturing (OEM) equipment and replacement units.

Features:

Brakes operate on a twin magnetic disk Hysteresis (constant torque) principle that provides overload and jam load protection
Mechanically assembled and field repairable
Permanent magnet technology—no power and no wear parts
Graduated adjustments for repeatable and recordable settings
Custom designs for unique applications
SMB-120, the largest permanent magnet brake available
Application CD-ROM for quick, reliable application solutions

Benefits:

Protects drive train
Low maintenance cost
Economical solution
Reduced setup time
Wider application solutions
Faster service

Applications:

Tensioning Brakes are used for a variety of spooling, winding, wrapping, tightening and machining operations.

Motor/drive overload protection
Soft start
Repetitive cycling operations
Bottle capping
Friction-band replacement

In the maximum, “like” magnetic poles are on the opposite sides of the center Hysteresis Disk. Magnetic lines of force travel through the narrow disk, producing a powerful magnetic field. In the minimum position, lines of force are relaxed, easing the magnetic field strength. As the hysteresis disk rotates through the alternating magnetic field, a resistance force builds. This resistance force is converted to constant torque unaffected by rotation speed.
