Air gap is used to produce magnetic flux between stator and rotor. Air gap is more uniform for the production of sinusoidal EMF in alternators to eliminate the harmonics. Air gap is more in syn machin...

Airgap is used to produce magnetic field between stator and rotor. Flux is produce in rotor winding, then torque develop and rotor is rotating, but if air gap is more between stator and rotor then more magnetizing current is required and also loss is more.
