Synchronous motor, like induction motor(ie asynchronous motor) is a commonly used AC motor. The synchronous motor is the heart of the power system. It is a component that integrates rotation and rest, electromagnetic change and mechanical motion, and realizes the transformation of electrical energy and mechanical energy. Its dynamic performance is very complex. And its dynamic performance has a great influence on the dynamic performance of the whole power system. The characteristics are: during steady state operation, there is a constant relationship between the rotor speed and the grid frequency N = NS = 60f/p, where f is the grid frequency, P is the pole number of the motor, and NS is called the synchronous speed. If the frequency of the grid is constant, the speed of the synchronous motor at steady state is constant and has nothing to do with the size of the load. Synchronous motors are divided into synchronous generators and synchronous Motors. The AC in modern power plants is mainly synchronous generators.
