Friction brake PMB series

electromagneticpermanent magnet

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. 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 YOUR APPLICATION Both the mounting flange and the output hub and armature assembly can be easily modified to fit your existing application. ZERO BACKLASH The PMB Series of Brakes have a spring mounted armature, which eliminates backlash in the brake. NO DRAG TORQUE When brakes are released, an airgap is present which completely releases the armature resulting in zero drag.
