Yes, the new set-up is running smoother and quieter than before & the addition of the drive controller has taught me something about AC motors. In my custom thread drive, the level of vibration & instability in the drive system can be assessed by placing a finger on top of four pressure rollers that guide the thread through points on either side of the flywheel. Mechanical vibration at these points has gone from moderate to almost nill. Previously, I had assumed that vibration at these points was generated by friction from the sleeve bearings in the guide rollers, or by torquing effects in the aluminum structure that supports the guide rollers. But undoubtedly this vibration originated at the motor. It's even more surprising that a large intermediate flywheel had failed to buffer any meaningful amount of vibration from passing through the motor-to-flywheel thread segment and into the flywheel-to-platter thread segment-- and from there, of course, into the platter. An inelastic thread is very revealing of such vibration as compared to a rubber belt.
