Magnetic Particle Brakes target clean room environments.

October 27, 2015

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 or with optional passive or forced air cooling. 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 holding applications, and permanent magnets can apply controlled stop if needed.<br /> Read More

Magnetic Brakes feature optimal torque to size ratio.

December 15, 2006

Available in 9 frame sizes from 30-120, PMB Series Thomson-Deltran Power Off Magnetic Brakes feature torque range from 45-4,250 lb-in. in dia from 3.30-11.89 in. and operating voltages of 24/90/190 Vdc. Adjustment collar allows brake torque to be varied to meet specific application needs. Brake case design provides heat dissipation, while fully potted coils meet minimum requirements for class F insulation, and splined hub with anti-rattle feature promotes quiet operation. Read More

Fail-safe Series SSB incorporates zero-backlash, permanent-magnet brake and torsionally rigid coupling to accept misalignment. Dual bearings allow greater overhung loads created by drive-belt pulleys, chain sprockets, and gearheads. Brake is available in 6 models, for NEMA 23, 34, and 42 sizes. Applications include robotics, linear, and rotary actuators, multi-axis positioning tables, material handling, and CNC tools. Read More
