Stator and Rotor Magnetic Field

The stator and rotor magnetic field is the resulting magnetic field generated by a system of coils that are symmetrically aligned. They are supplied with polyphase currents. The magnetic field is generated by poly-phase (two or more phases) current or single-phase current. In the latter case, two field stator windings are supplied and two resulting electromagnetic fields are generated beyond the stage.
