The main characteristic of a synchronous motor is the electromagnetic torque vs. load angle dependence. In synchronous machines the rotor and the stator magnetic field rotate with the same angular velocity. The load angle is measured between the rotor position and stator magnetic field. Without mechanical loading the load angle is zero - the rotor is always aligned with the stator field. As the mechanical loading increases, the rotor begins to lag behind the stator field and load angle increases.
We are going to simulate a simplified case. The power angle is predifined and the current in the stator winding is predifined. The task is to find a torque.
