FSB Series Electromagnetic Power-off Brakes

SKU: info-thomson-FSB Series Electromagnetic Power-off Brakes
Brand: Thomson

FSB Series brakes are designed in small frame size packages.

The brake coupling armature assembly is secured to a shaft by set screws.  Spring-set electromagnetic power-off brakes provide a safe, efficient means of stopping and/or holding a load in the absence of power. While the field (electromagnet) assembly is fixed and prevented from rotating, the rotor assembly is secured to the shaft. In the absence of power, the fixed and rotating components are engaged, thus stopping and/or holding the load. When the coil is energized, rotating components are disengaged thus allowing the shaft to freely rotate.
