BTW, if you reverse the rotor connections, the rotation direction stays the
same, but the relative position is shifted by 180 deg. If you reverse any
pair of stator connections, the rotation direction is opposite.
Isn't the web wonderful. last time I was looking for this kind of info
(more than 10 years ago), it was really tedious.
here you go:
http://www.polysci.com/docs/SynchroApplGuide.pdf
http://techaidproducts.com/PDFs/Tech-AidSynchroArticle.pdf
(note well the standard voltages given in this last article... )
And if you really, really want to get trained up, here's the NEETS textbook
on synchros (all 200 pages of it)
http://www.phy.davidson.edu/instrumentation/Files/NEETS/Mod15%20-%20Principles%20of%20Synchros%20Servos%20and%20Gyros.pdf
Long, but very good explanations of how they all work, what you can screw
up, etc.
