Nottingham stepped motor

I just recently bought a used spacedeck but still need an arm for it. While doing some inquires I can across this bit of information. That nottingham is the only TT manufacture that uses a stepped motor and that stepped motors are the worst possible choice because of 'cogging'. Brushless motors and syncronous motors have some rumbling but do not have cogging and are therefore better. DC motor,with precious metal brushes, eg Maxon are the best. (this last part I think I understand) Could someone explain the sonic effects due to cogging, and is this really a problem with nottingham TTs.

This is one of the quitest tables on the market,and all of thier tables use the same motor, this is one of the best aspects to the design.You will never hear anything bad from this motor, a little info can be a dangerous thing

I have had a space deck for a month now. I was concerned about the motor because you can feel it vibrate when it is stopped. I bought it because when it played, it was very quiet and seemed to sound right. A definite improvement over the Scout that I auditioned.

I think the Nottinghams in general are good sounding tables. Apparently they have made a good working system using the items they have selected.
