Magnetic Brakes

Mechanical Power Transmission

Permanent Magnet Brake has high-torque, zero backlash design.

May 2, 2016

Offering efficiency-optimized alternative to spring engaged brakes, PMB brakes come in 9 frame sizes, mount to motors and frames in any orientation (vertical, horizontal, and any angle in between), 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, runs from 4–90 msec optimize response times. At 2 in. dia, PMB typically yields ~40 lb-in. static torque.

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

Permanent Magnet Brake operates in temperatures to 140°C.

March 14, 2013

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

Brake plugs into servo and stepper motors.

May 30, 2002

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

Front End Brakes offer IP65 protection.

February 27, 2002

Available for NEMA 23 and 34 sizes and designed specifically to plug in to Stepper or Servo Motors, SSB Series incorporates zero backlash permanent magnet brake and torsionally rigid coupling to accept misalignment. Brakes are also available in NEMA 42 size offering IP65 splashproof and dustproof protection. All 6 models include dual preloaded sealed bearings and black anodized aluminum housing. Read More
