Hysteresis Brake & Clutch Accessories

Torque Current Curves
Nominal performance characteristic curves similar to that shown are provided by Magtrol. Precise calibration curves for individual brakes can be provided, but must be specified at time of order and do require an additional charge. Contact Magtrol for price and delivery of brakes complete with calibration curves.

Pillow Blocks
Pillow Block Assemblies are available for all brake and clutch units except the HB-840, HB-3500 and HB-3500M.
For detailed dimension drawings, click on the model’s underlined link. A PDF document will open. Adobe Acrobat Reader 7.0, or later, is required.) All other dimensions can be found in the corresponding data sheets.

[post_content] => The BPM Series Current-Regulated Supply Module is widely used to supply and control the current (up to 3 A) of Magtrol Hysteresis Brakes and Clutches. This compact component is easy to mount (DIN-Rail snap-on) and recommended for easily controlling a wide range of brakes and clutches.
The analog input of the Current-Regulated Supply Module is designed for 0 -10 VDC signals. At the maximum set value of 10 VDC, the output current is adjustable from 0 to 100 %. With the use of adjustable potentiometers, the zero point can be shifted from 0 to 20 %.

[post_content] => Magtrol Hysteresis Permanent Magnet Brakes and Clutches are ideal in applications where electrical power cannot be provided to a brake or clutch coil. While best suited to applications where fixed torque is to be applied, adjustable units can be made specifically tailored to the application. Typically provided as brake units, with the addition of an input shaft, the same unit can be used as a clutch. In a clutch application, the pole/case member becomes the drive element, and the rotor/shaft assembly becomes the driven element of the clutch with torque being transmitted through the magnetic air-gap. Magtrol Hysteresis Permanent Magnet devices provide all the superior operating characteristics of smooth operation, precise repeatability and long life inherent in our standard Hysteresis Brakes and Clutches.

[post_content] => When torque control/torque measurement must be performed at the highest possible power, Magtrol BHB Series Hysteresis Brakes are ideal. This design allows for continuous power ratings up to 6000 watts (7000 watts intermittent). Use of pre-loaded bearings in the BHB Series Hysteresis Brakes allows operation at speeds of up to 20,000 rpm for extended durations.
BHB Brakes are conveniently base mounted. Base mounting, with integral barrier type terminal strip, provides easy mounting and wiring.

[post_content] => In tension control applications that have multiple webs or multiple strands, it is very desirable to match the tension of each web or strand. This is most commonly attained by using a closed loop servo control system which controls current to a braking device through the use of dancer arms, follower arms and in-line tension transducers. The problem with such systems is that each web or strand must be individually controlled, increasing the cost and complicating the system with multiple sensors and power supplies.
Magtrol has developed a system to assure that every brake of a given model designation will be matched, at a predetermined torque and current point, to other brakes of the same model designation regardless of material and manufacturing tolerances. Each brake will be matched at the selected match point to within a tolerance of ±1%. The maximum deviation in torque from brake to brake at any point along their torque/current curve (from 0 torque up to the selected matched torque point) will be less than ±4% of the selected matched torque value. With this level of matching, a system with multiple tension rollers would provide tension consistency within ±1% if set at the matched point with all brakes receiving the same current. The matched point can be any value between 50% and 100% of rated torque, which allows the brakes to be optimized for specific applications. Unless otherwise specified, all brakes are matched at 100 rpm.
Typical vs. Matched Brakes
All single Magtrol Hysteresis Brakes can be matched. When ordering, replace the HB in the Hysteresis Brake model number with MHB. For Large Bore Brakes, LB is replaced with MLB. [table id=54 /]
