Direct Drive vs. Idler Drive vs. Belt drive

One could argue that if they have to add so many motors, the fundamental belt drive implementation might be flawed.

So, although I was joking about 4 motors and never dreamed there actually IS such a turntable, Burmeister have built it.  I'll probably never get to hear it, so I leave it to you to consider. But the more motors you have driving the platter, the less of the circumference of the platter can be contacted by the belt, which means a smaller "contact patch" and greater energy losses, more opportunity for belt slip, unless each motor or each pair of motors drives/drive the platter via separate belts.  I'd guess that is the case with the Burmeister.

Burmester, not "Burmeister".  I just looked at a photo.  One cannot see how the belts and motors are implemented but from the text, I am not sure.

Some more detail on the Burmester 175.

"The drive is not only equipped with its own tonearm and MC system, but also with a first-class phono equalizer, which is even supposed to keep the legendary stand-alone component Burmester 100 at bay in some areas. The barely compact turntable may still be worth its price of 31,800 euros, but its fighting weight of 60 kilos is not. This classy lathe is incredibly heavy!"

They are not joking as regards the pricing, I say! 🤭

The fact that the housing of the new Burmester 175 record player “builds so high” has, of course, also very practical reasons, after all, the developers packed in some key features. Above all, four motors, which, according to the manufacturer, are in the outer square around the sub-plate. One speaks here of the squaring of the circle, and relies on several belts, so that no uneven pull on the central bearing can arise. A total of four belts are used here, two for two motors each, which, according to the manufacturer, improves the synchronization, but also shortens the start-up.

The AC synchronous motors used here are driven by digital motor electronics, based on a high-precision oscillator and a perfect sine voltage. According to Burmster Home Audio GmbH, the electronics here are designed so that they are completely immune to fluctuations in the mains voltage frequency.
