Synchronous machines (generator and motor) in a nutshell
Two terms commonly used to describe the windings on a machine are field windings and armature windings. In general, the term "field windings" applies to the windings that produce the main magnetic field in a machine, and the term "armature windings" applies to the windings where the main voltage is induced. For synchronous machines, the field windings are …

Construction of Cylindrical Rotor Synchronous Machine:
The rotor has distributed windings which produce an approximately sinusoidally distributed mmf wave in space rotating at synchronous speed ω s rad (elect.)/s (n s rpm) along with the rotor. This mmf wave is represented by the space vector F f in the diagram and which at the instant shown makes an angle α = ω s t with the axis of coil aa' on the stator (coil aa' represents the phase a).
