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] => 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.

This method of braking provides far superior operating characteristics (smoother torque, longer life, superior repeatability, high degree of controllability, and less maintenance and down time) which make them the preferred choice for precise tension control during the processing of nearly any material, web or strand.

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.
