I had an idea to buy a Teres motor, and to mount it outside my Garrard turntable so that I would have the option of driving the platter via a belt or the idler wheel.It would be interesting to discover if the sound of the Garrard is really down to the idler drive.
Another, more off-the-wall idea Iwas that if a pair magnets were fixed on top of the motor spindle, then induced Eddy currents on the platter would cause it to spin.
This approach would very effectively de-couple the motor from the platter, however, the high torque would be lost, and I have no idea what speed the platter would settle at.
Here is a useful motor resource
