                    [post_content] => Like the Hysteresis Brake, the Magtrol Hysteresis Clutch develops 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, there is never any fear of contamination due to wear particles or leaky seals. This makes Magtrol Hysteresis Clutches and Brakes ideal for use in food processing and clean room environments.

                    [post_content] => Model 5251-2 is an open frame, 0-1A current regulated power supply for use with Magtrol hysteresis brakes and clutches. It has a high input impedance that allows for a variety of sensors and transducers to be used. It features a selectable 0-100 mV/0-5 VDC monitor out that allows connection to a PLC, voltmeter, display or other monitoring device. This allows the user to monitor the current applied directly to the brake or clutch, if desired. With regulated current, torque drift caused by temperature changes within the brake coil is eliminated. Braking control is enabled by using either a 10-turn potentiometer or by an external 0–5 VDC control signal.

                    [post_content] => For 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 of 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 Magtrol for more information.
Operating Considerations
Alignment Notes

 	


 	
The pole/case assembly and the rotor are shipped as separate items.
 	
It is the responsibility of the machine designer to assure proper alignment of the mating brake parts in the final assembly.
 	
These components must be mounted so that the concentricity and perpendicularity between the rotor and pole does not exceed the specified tolerances.
 	
Refer to individual LB model drawings for further details.



Additional Information
At the standard bore diameters, actual brake torque at rated current will normally exceed the minimum guaranteed values. Larger bore diameters can be provided, however, reductions in performance will result as bore diameters are increased. Any modification to a large bore brake should be reviewed in detail with Magtrol before ordering.
