The various types of machines differ fundamentally in the distribution of
the conductors forming the windings, and in whether the elements have
continuous slotted cores or salient poles. The electrical operation of any given
machine depends on
the nature of the voltages applied to its windings. The
narrow annular air gap between the stator and the rotor is the critical region
of the machine operation, and the theory of performance is mainly concerned
with the conditions in or near the air gap.
