Offering efficiency-optimized alternative to spring engaged brakes,Â PMB brakes come in 9 frame sizes, mount to motors and frames in any orientation (vertical, horizontal, and any angle in between),Â and have zero drag when energized. Hub is rigidly connected to shaft for zero radial movement between shaft and brake surface, allowing high-speed running without any noise,Â runs from 4–90... Read More
Available in shafted or thru bore models, MP-B Series provides torque ranges from 0.4–8,851 lb-in. Magnetic particle brakes deliver smooth, repeatable performance with silent operation and are suitable for applications that require torque independent of speed. Offering long, maintenance-free service life, space-saving units are available as standalone brakes orÂ with optional passive or... Read More
Featuring 17 mm max bore and 8,000 rpm max rating, 0.85 lb model PMB-06 comes standard with armature/hub and 24v coil but can be modified to specification. Size and 6.6 lb-ft of static torque make this brake suitable for medical and other portable applications. When brakes are released, airgap is present that completely releases armature for zero drag. Zero backlash suits servo and precision... Read More
February 5, 2009 Variable torque braking is at the forefront of electric forklift braking technology, and the Varistop permanent magnet brake from Matrix International applies this technology to address the challenge of increasing truck speed while reducing turning radius. The spring-applied motor and load wheel brake acccomplishes this by taking into account the changes in center of gravity with... Read More
January 28, 2009 Altra Industrial Motion offers a comprehensive series of electric forklift motor brakes, wheel brakes and permanent magnet brakes for OEM forklift manufacturers through its industry-leading brands, Warner Electric and Matrix International. The standard traction motor brake for parking and stopping is the electrically-released dynamic (ERD) brake. The ERD can be hydraulically... Read More
Ogura has just released their new series of Hysteresis Brake (PHT-D). The brakes operate via permanent magnets and are designed to deliver constant torque regardless of slip speed. Since there is virtually no wear, these units are ideal for constant tension applications, such as wire or film, but can also be used in a variety of torque limiting applications, such as bottle capping, fastener...
