Synchronous Machine: Functioning and Applications
Functioning
Rotor (Inductor)
The rotor, fed with DC, creates a magnetic field. In a salient pole machine, this field is considered sinusoidal. Rotating the rotor creates a revolving sinusoidal field.
Stator (Armature)
The stator has a distribution similar to an induction machine. The rotating magnetic field induces a voltage in each stator phase. These voltages are displaced, forming a balanced three-phase system.
Load and Field Interaction
When a balanced
