Not so strange

The Thorens TD 124 has an eddy brake and I believe that Teres is merely taking a page from Thorens' rim drive TT's. I don't see how they can get a patent on a widely distributed design, unless their brake design is different in application or construction.

Part of the issue is that a conventional belt drive has a tendency to build up momentum and it will reach a point where the momentum will exceed the desired speed. Most motor controllers reduce this effect by reducing voltage so that the motor is just barely pulling the platter assembly, and thus there is always a bit of drag for the motor to work upon. Here the sheer mass of the platter acts as a brake.

If your TT has speed adjustments, you can hear the effect by using a bit of grease instead of oil in the main bearing. The grease will do several things. It will 'tighten' up bearing clearance. Secondly, it will add a bit of drag, necessitating an adjustment to speed up the motor. In essence, you will be duplicating what the Teres motor is trying to accomplish.

I do this with a VPI TT with SDS and it works quite well with a noticeable increase in information retrieval.
