Esoteric magnetic drive tutntable

Dunno Mark this look like it has a hefty price tag.
 
Well, it’s mag lev but guided by a spindle to keep it in place, so it won’t run for a half hour.

But it should rain a while if the motor is not too close slowing it down.

Exaggerating about the half hour, but that does look like a huge rotating mass.

Iron there for the magnets to push (pull)

It is like those magnetically coupled fish tank pumps, no direct coupling. The damping factor sucks in that turntable setup. If you have a torque disturbance of any kind, it will take a long time for the control loop, if any, to counteract it.
 
There are some of those pumps in the oilfield where a direct coupled centrifugal's mechanical seals have compatibility issues with the pumped fluid. Some designs allow a separate fluid to flood the seal assembly.

Probably takes forever to get up to speed. I’m to used to being up to speed instantly. And lol put that dust brush away……

My brewing pump as well as my oil burner both use that design. No contamination risk from seal or trapped material in brewing and no risk of seal damage from unknown substances in the waste oil in my boiler. Some solvents will eat seals for breakfast. Learned the hard way. I burn most any liquid that is flammable (EXCEPT GASOLINE) or other low flashpoint fluids unless fully blended with heavy oil. I don't like the BOOM! Unless of course it's intended in my pyrotechnics.
