Why are synchronous motors not self starting?
Interesting. How is the rotating magnetic field created?
The rotating magnetic field is created by the stator windings, which are three-phase windings arranged around the stator. When an alternating current is applied to these windings, it creates a magnetic field that rotates around the stator at a constant speed. This is what causes the rotor to turn as well, since the rotor is magnetically coupled to the stator.
