Torque limiter
October 1, 2006

Mechanical torque limiters, also called safety couplings, are sensitive to the smallest increase of torque and disconnect the drive from the following masses in a split second, says Enemac, the manufacturer. Since the disconnection is forced, there is no effect on function in the event of a power outage. Type ECE is an axial short design, requiring a small installation space.
