In practice, it is usually better to wind the field coils on the rotor and supply the field current to them via slip rings. 

As the rotor turns, the changing magnetic field experienced by the stator coils induces a single phase AC output voltage in the stator coils 

A more sinusoidal waveform is produced - compared to the pulsing waveform produced by the AC Generator
