400Hz Servomotor

[RedRoby]

Hi to all!
I need of your help.
I have a lot of 400Hz Muirhead Servomotor-Tachometer generator mod.
15M81A,fom Mil surplus.
For 400Hz supply isn't a problem but I Don't have idea how to apply or
drivethis servomotors.
This motor is supplied with a 115Vac primary plus two 13Vac control
windings, one tachometer 115 Vac primary with a secondary output.
Do you have some suggestion, scheme, application notes for use this motors
in a light CNC project?
Will be welcome application notes, schematic, literatures or URL's for
this devices..

I please you to reply by email, many thanks in advance and sorry for
bandwidht..

Ciao from Italy....

A Google search turns up a lot of info. For instance - the
manufacturer's web site. Have you asked them for info?

Beyond that - is this the same system that used to be (maybe still is)
called a selsyn? These used to be common in a lot of military
applications, such as radars sets, to rotate something inside the ship
in synchronism with something outside the ship. If so, there is a lot
of info on the web.

I don't know Bill,
in my little experience I have find the selsyn as a "motor" with a exciter
winding and a tri-phase windig for position transmission with another
selsyn.
In my case I have a "motor" with a exciter windings and two separate low
voltage windings. In the tachometer section O find a exciter winding and an
output winding.
I don't know as I can use this 'motors' because I don't know theyr phisical
principes an pratical applications.... :-((((
In Internet I haven't find this gender of motors...
Thanks....
