Permanent Magnet Hysteresis Brakes & Clutches

Product catalog summary
Overview: The document provides comprehensive information on permanent magnet hysteresis brakes and clutches, emphasizing their non-electrical operation, absence of wearing parts, and precise tension control. These devices transmit torque through air, maintaining constant torque regardless of rotor speed and are suitable for harsh environments.
Specifications: The brakes and clutches feature internal clearances with tolerances under 0.025mm. Magnet assemblies surround the hysteresis assembly, with like poles generating maximum torque and opposite poles generating minimum torque. The design allows for infinite adjustability without surface contact, ensuring long-term stability.
Features: Key features include no electricity requirement, absence of break-away torque, constant torque, no friction elements, and no magnetic particles to contaminate products. Various designs, including custom options, are available.
Operation: Mag Tech brakes and clutches use ball bearings for light duty and tapered roller bearings for heavy loads. The central hysteresis disc ensures years of trouble-free performance. These units can function as couplings, pay-off brakes, or clutches, depending on the application.
Models and Dimensions: Detailed models include 513, 874, 527, 520, 655, MB6HD, 523, MB13HD, 535, 610, 806, MB70HD, and 663, with specifications such as torque range, bending moment, heat dissipation, weight, inertia, and dimensions in metric and English units.
Applications: Suitable for industries like capping, wire & cable, fiber-optics, aerospace, converting, power transmission, and medical. The company offers both standard and custom designs to meet specific needs.
Conclusion: Magnetic Technologies Ltd. provides a wide range of high-quality magnetic brakes and clutches, focusing on durability, precision, and adaptability. The document encourages consulting their website or contacting them for more information on custom designs and applications.
Additional Overview: The document also covers technical specifications and operational guidelines for constant tension brakes and accessories, detailing models, torque ranges, heat dissipation, dimensions, conversion tables, and selection criteria.
Additional Specifications:
  • Model 600 and 651: Designed for constant surface tension with urethane housing. Model 600-040L has a tension range of 0.23 to 3 kg and dissipates 28 watts of heat. Model 651-006L has a tension range of 0.014 to 0.50 kg and dissipates 13 watts.
  • Constant Tension Brake with Follower Arm: Models CT12, CT36, and CT70 offer torque ranges from 0.03 to 7.9 Nm and heat dissipation from 28 to 150 watts.
  • FastLock Collars: Available in various sizes, these collars allow for fast locking and unlocking without tools, suitable for non-hardened shafts.
Procedures and Recommendations:
  • Selection Criteria: Determine torque, maximum RPM, and bending moment for each application to select the correct shaft or coupling.
  • Operating Curves: Use the provided curves to ensure applications are within safe operating ranges. Continuous duty is represented in blue, intermittent duty in yellow, and overheating risk in red.
Accessories:
  • Spool Adaptors and Drive Plates: Various models are available to fit different brake sizes, with specifications for dimensions and mounting options.
  • Custom Payoff Stands: Multi-position stands are available for different applications, with options for horizontal and vertical configurations.
Conversion Tables: Handy tables are provided for converting units of torque, force, length, velocity, temperature, and inertia.
Applications: Examples include tensioning films and foils, torque limiting, and powered take-up applications, demonstrating the versatility of the products in various industrial settings.

\/mr.Mmr TECHNOLOGIES LTD. Why Mag Tech Brakes & Clutches are Better Ball bearings for light duty or tapered roller bearings for heavy overhung loads guarantee the right brake for your application. We magnetize all our own magnets to give you the right amount of poles, gauss and saturation for your application. This guarantees that brakes and clutches purchased from us years ago are the same as those purchased today. Special clamping arrangement allows easy disassembly and interchangeability should you decide to change a shaft, or to service our brakes at some time in the future. The hysteresis...
