Hysteresis Brakes |
     |
| |
| 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. |

| 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. |
| |
 |
Magtrol
Hysteresis Brakes provide precise control of wire tension
during wind, hook and cut operations of high speed automated
winding machines. |
 |
Transformer
and coil winding operations employing Hysteresis Brakes
in open loop control for maintaining precise tension during
winding process. |
 |
Precision
gap control using Hysteresis Brake and photo sensor. |
 |
Unwind
tension control by means of follower arm with potentiometer,
Hysteresis Brake and controller. |
 |
Magtrol
Hysteresis Brakes offer frictionless, non-breakaway force
for tensioning materials during slitting and many other
material processing operations. |
 |
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. |
 |
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. |
 |
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. |
 |
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.
