magnetic drive turntables



Transrotor Orion turntable

This form of magnetic drive is getting more use in high end turntables, such as the Clearaudio Statement and EAR Disk-Master. I see it as a variation of direct drive, except, in this case, the subplatter is being belt-driven by three motors. In plain English, the top platter is magnetically driven by a belt-drive turntable at the bottom. Imaging replace the whole motor pod with a stator or direct-drive motor at the bottom, what you have, in essence, is a direct drive turntable. There are many possibilities in this implementation and it's nice to see some novel ideas.

Your thoughts?

Teres, you are right about it being more like a double compliant system, closer to belt-drive than direct-drive. I guess I was intrigued by the idea of the platter being center driven. Using the same set up and if I replace the motor pod with a stator, coils, then it will act like a direct-drive table except the stator is decoupled from the main chassis to avoid back torque energy (good). For yucks, just an idea...

Thanks for chiming in.

I believe Transrotor uses a similar system.

Technics SL 1200 has a magnetic direct drive mechanism that sandwiched between the platter. It is not priced at 50k.
