Hysteresis Brakes

Specifications-EnglishSpecifications-MetricApplicationsData SheetManual
 
Pure Hysteresis Brakes produce torque strictly through a magnetic air gap without the use of magnetic particles or friction components. This method of braking provides far superior operating characteristics (smoother torque, longer life, superior repeatability, high degree of controllability, and less maintenance and down time) which make them the preferred choice for precise tension control during the processing of nearly any material, web or strand.

* Kinetic power ratings are maximum values based on limiting coil and/or bearing temperature to approximately 100 ºC, and should not be exceeded. Actual values in service may vary ±50% depending on mounting, ventilation, ambient temperature, etc.

*Standard coil voltage is 24 VDC. 90 volt and non-standard coil voltages are available. 12 VDC coils are available on HB-2.5 through HB-840 models.

Applications
Magtrol Hysteresis Brakes provide precise tensioning for: armature and coil winding, printing and labeling, wire marking, braiding, material slitting, sheeting, weaving, and many other material process applications. They are ideal for any material, strand or web, including: copper wire, fiber-optic cable, textiles, tapes, films, foils, paper, rubber products, nylon, and many others.
 
Wind hook Magtrol Hysteresis Brakes provide precise control of wire tension during wind, hook and cut operations of high speed automated winding machines.
coil winding Transformer and coil winding operations employing Hysteresis Brakes in open loop control for maintaining precise tension during winding process.
gap control Precision gap control using Hysteresis Brake and photo sensor.
follower arm Unwind tension control by means of follower arm with potentiometer, Hysteresis Brake and controller.
slitting Magtrol Hysteresis Brakes offer frictionless, non-breakaway force for tensioning materials during slitting and many other material processing operations.
bike The indefinite repeatability, controllability and longevity of Magtrol's Hysteresis devices has earned them recognition in high end, state-of-the-art exercise equipment applications where precise load control and programmed repeatability are essential.
The Magtrol Hysteresis Brake is used in precision computerized diagnostic equipment, as well as in regular exercise machines
.
duty cycle Magtrol Hysteresis Brakes are widely used in load simulation applications for life testing on electric motors, actuators, small gas engines, gearboxes, and many other rotating devices and assemblies. The ability of hysteresis devices to withstand high temperatures for prolonged periods of operation without suffering any degradation to their magnetic structures makes them ideal for these applications, as well as environmental testing, and even applications in outer space.
dyno brake Their ability to produce torque independent of speed makes Hysteresis Brakes the preferred method of braking employed in many dynamometers used for performance testing of motors, actuators, gas engines, etc.
load simulations Their ability to produce torque independent of speed also makes Hysteresis Brakes valuable in applying pre-loads for preventing backlash, backdriving loads, and in limiting torque to prevent damage to delicate assemblies.
