A torque limiter is a mechanical overload protection device designed to protect mechanical equipment from damage. The torque limiter trips when an excessive torque load occurs and physically disconnects the drives and driven components almost instantaneously. This protects the machine from seeing excessive loading due to the accumulated rotational energy upstream of the torque limiter. The protection provided could mean avoiding expensive machine crashes or secondary disasters. This is a very applicable means of protection, but numerous factors need to be considered before the torque limiter method is chosen.
