Why three motors?



Can someone enlighten me on the wisdom of having a three motor turntable like the TW Acustic with only ONE side of the belt touching the platter?

Here is an example.

I just don't get it...

Thanks Dgad, interesting post. Are the motors with the BN the same as the AC 1/3? I thought from pics they looked shorter/smaller and if so might have less torque. What I am wondering is; if the AC 1 motor is stout enough the addition of more doesn't add much. Where as if the BN may have been designed to use 3 smaller motors and thus the test with one compromises the set up.

I also wonder what parts of the BN give the most improvement over the ACs. Very different materials are used for platter and plinth. I also wonder if a BN platter on an AC would be the value upgrade if it can be done.

Thanks, Terry
