The encoder is described as a "Resolver" in the drive manual, but

I have a servo motor acquisition problem, I tend to buy servo motors
from eBay just because they are cheap.

I happen to have a disk motor here in my workshop museum that apparently
uses the same principle, about 12 cm diam., very flat. It runs without
electronics, so I supposed it had brushes inside. The rotor must be also
etched from a disk of sheet copper, simply plane, rotating between two
rings o

This looks like a wound-up linear drive: high torque because of large
radius, but high demand for precision mounting. Very interesting, also
for other things than tools and machines (e.g., quick pointing telescope
and dome drives). Not shown is the drive electronics - like in the used
car ads,
Some of these seem to be just begging to be wrapped round a ball screw nut.

The idea that there is no such thing as objective truth is, quite simply, wrong.
