400Hz Servomotor
 

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
drive this servomotors.
This motor is supplied with a 115Vac primary plus two 13Vac control
windings, plus the tachometer with a 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..
