Why three motors?

Sorry, I should have asked the question differently. With three motors, why have ONE side of the belt touching the platter? It's the belt arrangement that I question. What is the point of that? With two motors, side torque is eliminated or equalized so the platter bearing is not pressured towards one side. In the TW Acustic, it appears at least to me, the whole thing is an afterthought on cashing in on selling more motors and the original plinth design was not intended to have three motors to arrange the belt in an equilateral triangle so all three sides of the belt can touch the platter. Instead, the arrangement end up having only one side touching the belt. Wouldn't two motors be better in this case? What I see in the picture is bewildering to me. Am I missing something here? Please illuminate me.

The latest Raven turntable abandoned such scheme and opted for three motors in a single housing, which is also questionable in itself.

the two arms is probably to be able to do a reverb if you manage to drop them slightly simultaneously having a 4ch phonostage... just kiddin'-)

The way it is arranged in the photo does look a little odd. Any idea what the tonearm with the wooden armpipe is?

This is typical german engineering. If one motor fails you still have instant replacement on hand.....

Please illuminate me

Simple answer: That's Higher End

*Sad* Personally I feel discriminated with a 1 motor Design.
