HYSTERESIS TENSIONING BRAKES

By helping control torque variations, tensioning brakes preserve drive train life in winding operations. By relying on magnetic resistance (hysteresis), Sjogren’s brakes require no external power source and have no mechanical wear parts (other than ball bearings). The four most common applications are: material unwind operations for payoff applications; coilwind operations for constant tension using a nip roll; material handling operations for electric motor overload protection; and tightening operations for repetitive cycling/tightening.

The unit is mechanically assembled (not welded), making replacement of bearings a simple field repair
The magnet-based technology maintains permanent, consistent levels of resistance and experiences no friction wear
Repeatable and recordable settings make it easy for the operator to control torque precisely, and to reliably vary settings from one application to another

ADDITIONAL DETAILS

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.
