Abridgment of two-reaction theory of synchronous machines generalized method of analysis — Part I

STARTING with the basic assumption of no saturation or hysteresis, and with distribution of armature phase m. m. f. effectively sinusoidal so far as regards phenomena dependent upon rotor position, general formulas are developed for current, voltage, power, and torque under steady and transient load conditions. Special detailed formulas are also developed which permit the determination of current and torque on three-phase short circuit during starting, and when only small deviations from an average operating angle are involved.
