Two phase AC Servo Motor

Two phase AC Servo Motor: For a low-power (a few hundred watts) control application, a balanced Two phase AC Servo Motor is ideally suited as it can be driven by…

Speed Control of Induction Motor

Speed Control of Induction Motor: Stepless control of speed of induction motors cannot be carried out as efficiently and inexpensively as for dc motors. Various methods of Speed Control of…

Short Circuit Current in Synchronous Generator

Short Circuit Current in Synchronous Generator: The Short Circuit Current in Synchronous Generator being electrical in nature is much faster than the electromechanical dynamics discussed already. It will, therefore, be…

Synchronous Machine Operation

Synchronous Machine Operation: The Synchronous Machine Operation are examined here under conditions of variable load and variable excitation. One of these quantities will be assumed to be held constant at…

Armature Reaction in Synchronous Motor

Armature Reaction in Synchronous Motor: The Simple circuit model of the synchronous machine was obtained in Sec. 8.3 by making the assumption that the magnetic circuit of the machine is…

Equivalent Circuit of Synchronous Motor
