Fig. s a Clutch he unit is connected to a motor by a timing belt or gear. he housing is driven and the shaft is the output end. Fig. s a Payout Brake Brake is stationary and the reel or material is fitted to the output shaft. he tension on the material will vary with the diameter. HOW HEY OPEE: For Maximum orque ll important internal clearances are ground to tolerances of less than. in. (. mm). Magnet assemblies surround hysteresis assembly. 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. PHOE:.. FX:.. Hysteresis ssembly % % % % % % % % Maximum orque Fig. Fig. Fig. % % % % For Minimum orque When opposite poles face each other they produce minimum saturation of the hysteresis disc. he lines of flux travel through the hysteresis disc. Combinations of adjustment angles between the two extremes give infinite adjustability. Because there are no contacting surfaces, the setting can be maintained indefinitely.

HOW O UE HE CUVE: Find the slip rpm on the X-axis and the torque on the Y-axis. otice the areas that represent safe, continuous duty; intermittent duty, such as five minutes on, five minutes off; and the area which is not recommended. Operating above that line for any period of time will cause overheating and possible damage to the unit.
