Apparently, TTs are so mysterious that anything goes, as long as it's long, convoluted, and circular.  Multiple DC motors "make sense" if one starts by believing that an AC motor naturally slaves to its sine wave and polarity, and that this behavior is problematic, on the face of it.  The multi-motor gambit is just an extension of the notion that it is not only possible but a good idea to drive the platter at the perfect speed with the motor or motors as the means for so doing.  Basically, 3 motors "average out" better than one, not to mention the "benefit" of "balanced tension on the bearing". Rim and direct drive are sub-sets of the "motor-in-control" thinking.  Hats off to Linn, who first planted the idea of the dominant motor in the fertile minds of the light-weight/PRAT fraternity. From such humble, verbose beginnings, the Strong Motor idea seems like a perfectly "reasonable" bid for a significant slice the Heavy Platter Up Market.

To provide even more opportunities, I provide the following grist for the TT mills: Lately I have been wondering about the "micro-controllers" that "regulate" the motor speed(s) on many modern TTs, whether these switching components flood enough hash into the lines to affect any analog parts of the proceedings.
