When your "first" motor was synched though, wouldn't this have to be to a third "master" motor, to give the circuit a comparison reference? Only then could its spiky correction waveform be generated.
After that though, you could sync to any number of motors at once, in series or parallel, given enough power from the sync output circuit and appropriate drive voltage and current.

PS. If you simply joined exactly similar commutator-type motors in series across a DC supply, I reckon there would be a sync effect too.
I was thinking DC commutator type motors when thinking about this .
The problem i was wondering about was Nipkow disc as a camera and monitor it must be hard stopping the small amount of monitor light getting to the camera side there has to be a gap between the disk and light barrier between two .
Thinking it would be nice to keep the camera monitor idea in a separate enclosure with the easy same syncing idea as a same disc or shaft but do it with wire without another control circuit .
I have no idea really never tried it ,Steve just a hunch in that it must be logical two of the same motors would run at the same speed so long as one is feed back controlled useful for NBTV.
It would make a mechanical camera a little more versatile as to where you wanted the monitor mounted .
The electromagnetic spectrum has no theoretical limit at either end. If all the mass/energy in the Universe is considered a 'limit', then that would be the only real theoretical limit to the maximum frequency attainable.
