Current Controlled Hysteresis Brakes

Product catalog summary
Overview of Hysteresis Brakes: The document provides comprehensive technical details on current-controlled hysteresis brakes, highlighting their applications, benefits, operating principles, and technical specifications.
Applications: Hysteresis brakes are primarily used for precise tension control in winding processes, such as high-speed automated winding machines and transformer coil winding. They are also utilized in load simulation for life testing of electric motors and other rotating devices.
Advantages: These brakes offer frictionless torque transmission, extended lifespan due to minimal wear, superior torque repeatability, a broad speed range, and smooth operation. They are more reliable and efficient compared to friction and magnetic particle devices.
Operating Principles: Hysteresis brakes function using a magnetic air gap between a pole structure and a rotor, enabling torque control without physical contact. Torque is adjustable via a field coil in electrically operated models, while permanent magnet models provide constant torque.
Technical Specifications: Detailed tables in the document outline dimensions, torque values, working current, resistance, and other parameters for various models, aiding in the selection of the appropriate brake for specific applications.
Design and Function: The design features a pole structure and a rotor/shaft assembly that are not in physical contact, ensuring smooth operation and high performance across a wide speed range.
Overview of Mechanical Components and Force Measuring Devices: The document also covers technical specifications and descriptions for mechanical components like flexible couplings and force measuring devices.
Flexible Couplings (WKK): Designed for driving or driven parts, these couplings accommodate various shaft diameters and feature a keyway and slot tightening to eliminate play gaps. They include an elastomer middle section, with special bore dimensions available upon request. Specifications for different sizes include dimensions, material, and torque figures.
Force Measuring Roller (RMGZ 100): This device measures tension in wire and similar materials using a flexion beam principle. It includes lifetime lubricated ball bearings and offers a 20:1 force measuring range with 10 times overload protection. Specifications include nominal forces, load rating, and temperature range options.
Force Measuring Sensor (C 203 Series): These sensors are designed for material tension measurement in automated processes, offering high accuracy and reliability. They use a dual flexion beam design with mechanical overload protection, reducing the need for frequent recalibration. Specifications include nominal forces, sensitivity, and temperature range.
Additional Information: The document provides order codes, options for connectors and mounting, and contact information for various international distributors.
