High quality AC turntable motor

The Townshend Merlin costs over £1200 UKP - and is essentially a mains sine wave re-generator. I contacted K&K - Kevins a nice guy BTW - his design, which is scheduled for next year, seems to follow the principle of the Rega P9 power supply that smooths out the power by angling the power into the motor to prevent the cogging. I am grateful for the feedback from the motor experimenters!

Whilst I understand that there is a school of thought about getting up to speed, and then simply maintaining it approach, I am beginning to be drawn down the high torque route. I am beginning to notice slight drag in very heavy and complicated passages on my current deck, which is why I wanted to use a higher torque option.

Hi Lewm - sorry for my lousy phrasse 'angling the power' I understand that with a 24 pole synchronous motor they can be made with 4 coils. If 2 opposing coils are driven, and then the other ones which sit at 90degrees to the driven ones are also driven then this ought to significantly reduce the ripple. PErhaps a fair analogy would be a two stroke to a four stroke engine. If it is the case that we have a higher torque motor, it's the magnets that help increase the torque, along with the commutator windings and thickness. As this increases, so does the clunking/cogging. That is why I want something that helps reduce this. A pure sine wave regenerator simply re-creates the 50 hz - it does not provide me with those 90 degree opposed waves to drive the other 2 coils. I hope that I make sense andd am barking up the right tree.
