DESCRIPTION
As with all Magtrol hysteresis products, the HCF Series
Hysteresis Clutches develop torque strictly through a magnetic
air gap, ensuring an absolutely smooth transmission of torque
from the drive unit to the driven element. Designed to be
powered without the use of brushes or slip rings, and being a
pure hysteresis device that does not rely on friction elements
or magnetic particles, there is never any fear of contamination
due to wear particles or leaky seals. This makes Magtrol
Hysteresis Clutches ideal for use in food processing and clean
room environments.

APPLICATIONS

Precise control of torque for capping, bolting and other
screw applications
Torque limiting in order to prevent over torque and
provide precise, stable and smooth application of torque
Closed-loop winding tension and speed control

t *t Other coil voltages are available.
t **t 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.
