HCF Series Hysteresis Clutches FEATURES • • • • • • • • • Torque up to 1.8 N·m Speed up to 3600 rpm Power up to 450 W Torque independent of speed Long, maintenance-free life Operational smoothness Superior torque repeatability Broad speed range Excellent environmental stability 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. 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 Minimum Torque at Rated Current mN m 56.5 113 226 850 1800 Rated Current Maximum Speed Kinetic Power** 5 Minutes * Other coil voltages are available. ** 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.

Hysteresis Principles PRINCIPLES OF HYSTERESIS Overview The hysteresis effect in magnetism is applied to torque control by the use of two basic components –a reticulated pole structure and a specialty steel rotor/shaft assembly–fastened together but not in physical contact. Until the field coil is energized, the drag cup can spin freely on the ball bearings. When a magnetizing force from either a field coil or magnet is applied to the pole structure, the air gap becomes a flux field. The rotor is magnetically restrained, providing a ROTOR braking action between (Drag Cup) the pole structure and...
