Electromagnetic clutches and brakes from jbj Techniques Limited

Permanent magnet brake designed for industrial and mobile applications. Brake force is produced via magnets which reduces both size and weight of brake versus spring applied brakes.Armature is mounted via springs which eliminates backlash. Standard brakes can accommodate temperatures up to 140deg C. Brakes can be tuned to provide a controlled stop. Output assemblies easily modified to fit your application. UL and CSA Recognized as a component for use in motion control systems. Approved in accordance with UL508, 17th edition andCSAC 22.2 No. 14-13, 12th edition. High Torque Compact Design. Because permanent magnets are used versus springs, the overall size of the brakes is smaller for a given torque size. Because the brakes are smaller, their weight is also less, which can be an advantage in some applications. Controlled Stop. Since torque is directly controlled by flux, a brake can be tuned to provide a softer stop in an application versus having full torque applied. Easily Customized For YourApplication. Both themounting flange and the output hub and armature assembly can be easily modified to fit your existing application. The standard magnetic material used in the brakes can accommodate temperatures up to 140 degrees celsius. If an application requires it, special material is also available on some sizes to accommodate higher temperatures. No Drag Torque. When brakes are released, an airgap is present which completely releases the armature resulting in zero drag. Brakes require a variable power supply tomake sure they are properly tuned for an application. The PMBSeries of Brakes have a springmounted armature, which eliminates backlash in the brake. HighOperating Temperatures. Zero Backlash.
