How does back EMF affects synchronous motor?

Back EMF (Electromotive Force) is an opposing voltage generated by the rotor of a synchronous motor when it rotates. In synchronous motors, the back EMF plays a crucial role in maintaining the synchronization between the rotor and the stator magnetic fields. If the rotor speed changes, the back EMF also changes, which causes a corresponding change in the current flowing through the DC excitation field.
