Electroid SSB Brakes

SSB Brakes

Electroid's Model SSB Brakes were created as a solution to braking applications on stepper/servo motors. Compact, powerful, and with zero backlash, they are the standard for front-end stepper/servo motor brakes. The Failsafe Brake design offers a high degree of safety, even during a power failure; the simple "plug-in" design incorporates a torsionally rigid coupling to accept misalignment. The dual bearings allow greater overhung loads created by drive belt pulleys. chain sprockets and gearheads. The zero backlash armature permits the encoder to read exact positioning and the torsionally rigid coupling allows for misalignment of the motor shaft without putting stress on the dual output bearings. The permanent magnet brake provides extremely fast response times and very low inertia.
