Matched Hysteresis Brakes

Matched Hysteresis Brakes with shaft on one or both sides

 

These units are developed to asure that every brake of a given model desiguation will be matched at a predeterminated torque and current point to every other brake of the same model designation. By possibility of a special adjustment each brake will be matched at the selected match point to within ±1.5% provided that the match point is above 50 % of the max possible torque. All other points of the curve then are within ±4% deviation from each other. The use of matched hysteresis brakes is for example of advantage for a multi tension control system for multi spool payoff frames.
