Function
Magnet assemblies (outer discs) surround our
hysteresis assembly (center disc). When like poles face each other,
they produce maximum magnetic saturation of the hysteresis disc,
forcing lines of flux to travel circumferentially through the hysteresis
disc. This produces maximum torque. When opposite poles face each
other, they produce minimum saturation of the hysteresis disc. The
lines of flux travel right through the hysteresis disc. Combinations
of adjustment angles between these two extremes gives infinite adjustability.
Because there are no contacting surfaces, the setting can be maintained
indefinitely.
Advantages of permanent magnet hysteresis brakes
Built in ball bearings enable the units
to carry sufficient load on the shaft
Shaft length and diameter can be manufactured exactly as per customers
requirements
Precise adjustments of torque care for best repeatability of torque
Precise ground strong enough magnets care for friction-free movement
and long lifetime
Applications with hysteresis brakes
Tension adjustment with thin wire also
after anealing
Tension adjustment at winding wire with high sensibility
Use as torque limitor * Adjustable torque load on test benches
On bunching machines as improvement for tension equalizing of the
in-running wires
Using these units as couplings the applications
are such as drive transducers for spooling wires, tapes, threads,
ropes etc. |
