Broken Couplings

Broken Couplings
Vol.21 #1, June 1994

If you have problems with broken couplings between DC motors and tachometers, try switching to a stiffer coupling.

It is possible for the combination of the rotational inertia of the tachometer and the torsional stiffness or the coupling to result in a torsional natural frequency close to the frequency generated by the firing pattern of the DC drive's SCRS. When this happens, the coupling can be destroyed very quickly.
