Nexen servo motor brake modules mount between the servo motor and the gear reducer or on the free end of a ball screw spindle. Nexen offers a wide range of sizes and flanges to fit any brand of motor. These zero backlash brake modules are ideal as redundant safety brakes for z-axis applications or to stop high inertia systems from coasting after a power interruption. The spring applied brakes offer high holding torques and short emergency stopping distances.
