Securing Mechanics to Motor ShaftsTeknic

 · One of the most common points of failure in automated machinery is the coupling point where the motor shaft attaches to the mechanics. This is especially true in demanding motion control applications—those that include frequent start/stops bi-directional control frequent changes in torque direction etc. (less common in applications that are constant velocity and one direction such as a fan).
