Protection of an electromechanical system from torque overload is often assumed to be guaranteed by the current limits set in the drive parameters.

But in the case of hard stops, impacts and other situations where overload occurs rapidly, sufficient energy to do damage often exists in the rotating inertia driving the load. R+W servo-rated torque limiters are accurate to +/-5% release torque and positively disengage the motor or gearbox shaft in 1-3 milliseconds. Patented preloads and a specially designed spring system remove backlash and guarantee a low profile. Selection tool and personal sizing assistance are available at www.rw-america.com.
