# Abstract:

An nalysis is presented of the output voltage from a control transformer in a simple control system in which the rotors have the same uniform angular velocity relative to the stator windings. The analysis given is by means of the Kron methods used in previous reports in this series, but suitably modified for the present case. The main result given is a formula for the output voltage as a function of impedances, angle of separation, and velocity of rotation. Under the approximation that the transmitter impedance level, is negligible in comparison to the transfor er impedance level, the expression for the output voltage is considerably simplified. In particular, the major dependence of output voltage on impedance is on the ratio of the real and imagi ary parts of a single transformer impedance. By means of the formula for the output voltage, it is shown in contrast to the stationary case, that the voltage is never zero when the synchros rotate. A formula for the position of the minimum output voltage is also given. Many of he results derived analytically are present d in graphic form. Author
