introduction：Synchronous motor，And induction machine（Asynchronous motor）The same is a commonly used AC motor。Synchronous motor is the heart of power system，It is a set of rotation and rest、Electromagnetic changes are integrated with mechanical motion，A component that converts electrical and mechanical energy，Its dynamic performance is very complex，Moreover, its dynamic performance has great influence on the dynamic performance of the whole power system。The characteristic is：Steady running time，There is a constant relationship between the speed of the rotor and the frequency of the gridn=ns=60f/p，amongfGrid frequency，pIs the number of poles of the motor，nsCalled synchronous speed。If the frequency of the grid is constant，The speed of the synchronous motor in steady state is constant and has nothing to do with the size of the load。Synchronous motor is divided into synchronous generator and synchronous motor。The alternators in modern power plants are mainly synchronous generators。
