Mark, that's very interesting. I assume it would be possible to build a power supply that supplies 3 AC waves for the motor that are exactly 120 degrees apart? Would that overcome the potential hard-to-predict oscillation that you mentioned? Would this lead to a much quieter and smoother turntable drive?

What would the "best" frequency be for the power supply to generate? Is there a set of formulas around that an ordinary statistician might be able to understand for calculating the optimum voltage, frequency and current requirements for the power supply, given the motor's load, speed, etc.?

Actually, this is probably all too complicated for a forum like this. Could you point me in the right direction for exploring these concepts?

Thanks!
