High quality AC turntable motor

I am looking for a high grade AC motor for my Townshend Elite Rock turntable.
The current motor is specified to run at 110v 250rpm. I reckon that it's got very little torque. I have considered the phillips and the premotec - but they appear to offer no real alternative so far as specs are concerned with what I have.

I have seen a couple of motors on the RS Online website by the likes of Berger, and Crouzet. The Crouzet motor intrigues due to it's high torque rating. my concern is whether or not it is noisy, and vibrates a lot.

Does anyone have experience with these motors? or does anyone have any suitable suggestions?

I intend to try out a few different power supplies on the deck at some point.

Hi Palasr, Would Sound-Carrier's motor controller meet the standards that you outline (phase angle, harmonic distortion, and individual phase amplitude)?

Palasr, You are correct; the Walker MC is likely to be pretty much like the SDS. This is what I was referring to in my previous post "most" current commercial controllers do not actually split the phase of the AC.

I am awaiting delivery, as I mentioned, of Mark's second generation controller. It's a finished product, not a kit.

Lewm, can you let me know how I can potentially obtain one of these second generation controllers? Are they currently available? Feel free to message me if that seems more appropriate than posting publicly.

Googling has yielded little for me in my search for one of these.

Hi Lewm, I also would like to know how to acquire Mark Kelly's second generation AC motor controller.

If the controller does not split phase (relies on a capacitor in the motor to split phase), then I would expect that one is better off moving the belt on a pulley rather than electrically switching speed.

The motor controller for the Basis turntable does properly split phase in the controller, sending two separate power lines to the motor. The motor has to be modified in order to use the controller (one cannot just plug the motor into the speed controller).
