Servo Motor Safety Brake
STOBER’s servo gear units can be paired with our ServoStop, an integrated safety brake. It’s ideal for vertical applications and provides redundant braking. It prevents slipping or falls, even when the motor is removed.
As the manufacturer of the world’s toughest gear boxes, you can count on us to equip servo motors with brakes that deliver the highest levels of performance and reliability. Units featuring this servo safety brake perform critical functions across a number of industries, including automotive manufacturing and aerospace. Our in-house expertise and history of innovation mean we can design fully customized solutions for your particular applications, as well.
The ServoStop external servo motor brake provides dynamic braking during power failures or emergencies, helping your operations achieve maximum safety conditions. It fits all standard servo motors and allows for dismounting of the motor even while it is engaged, meaning installation and maintenance is as simple and convenient as it can be. Our servo motor holding brake meets the EN ISO 13849 safety standard, so you can feel secure about adding it to your equipment. This unit also is available with manual hand release.
