The exciter voltage is much lower than your unit as marked. It is something like 12 or 24 volts.
It looks externally like yours.
Hi, the more I discover about synchros, resolvers, RVDT's, and now this motor, the more I find there are a lot of very similar appearing devices with subtle differences!

I'm sure this is a motor, it has to be. Based on Ron's previously posted book photos, I just now need to try and operate it! Will start out on lower voltage (and hence power) with no load to prove the theory without damaging it before going to 115Vac.

Cheers, Scott.
