many years Magtrol has designed Hysteresis Brakes with large
bores, and without a shaft or bearings. These brakes are used
for superior tension control for helical wrapping, braiding
and other feed through applications. Magtrol Large Bore Brakes
are used in machines for manufacturing cable, wire, fiber
optic cable, rope and tape, among others. Magtrol Large Bore
Brakes provide smooth, repeatable torque, largely independent
speed. Maximum speeds up to 8000 rpm are available.
These brakesconsist of two primary parts: a pole/case assembly
and a rotor. The pole/case assembly is usually mounted in
a stationary position within the machine, while the rotor
is shaft mounted concentrically within the pole/case assembly.
The pole/case assembly and rotor are available are manufactured
in standard bore sizes
and hole patterns. Variations to the
standard dimensions can be made based on customer requirements.
Certain modifications to the brake, such as a larger bore
dimension, may impact its performance ratings.
Additional options available include rotor
mounting flanges, power supplies, torque-current curves and
other coil voltages. Contact
