Default Re: SMITHS "servomotor" 1111SCM-2

There is also in Upson and Batchelor's book a diagram of a "Simple AC position Servo" in another chapter which might indicate the system that your servomotor drives. Feedback from the synchro Control Transformer drives the Servomotor amplifier input.
This may help.
