Abstract :
This paper examines the operation of a magnetic servoamplifier in which the load circuit includes the resistance and inductance of a servomotor control winding shunted by a tuning capacitor. Amplifier parameters (tuning capacitor C, limiting resistor Rs, and quiescent firing angle ¿) are being optimized for best linearity and maximum motor torque. Amplifier motor transfer characteristics are established. The results are illustrated by a numerical example and verified by experiments.
