The system includes precision servo potentiometers, A.C.Servo motor with gear train, servo amplifier and associated power supply along with test points and detailed instruction manual. The pair of precision servo potentiometers is working as error detector. This pair is excited with the help of floating 50HZ supply. This output is amplified with the help of a differential amplifier having very high CMRR. The differential amplifier outuput is further processed before it is fed to the control winding of A.C. servomotor (two phase) amplifier gain is controllable. Varioustest points facilitate clear understanding of the entire system
