When the synchronous machine is connected to an infinite bus, its speed and terminal voltage are fixed and unalterable. The control variables are only field current and the mechanical torque or load on the shaft.
WebThe torque developed in a synchronous motor is directly proportional to the applied voltage unlike in an induction motors where it is proportional to the square of voltage. Hence it is less sensitive to voltage variations. The Torque Speed Characteristics of Synchronous Motor is shown in Fig. 1.34.
