This chapter uses the results of Chapters 1 and 3 to explain how a radially directed rotating magnetic field can be established in the air gap of AC machines. In particular, the notions of distributed windings and of sinusoidally wound turns (phase windings) are explained. Ampere's law is then used to show that a sinusoidal (spatially) distributed radial magnetic field is established in the air gap by the currents in the phase windings. The concept of flux linkage in distributed windings is explained and the chapter ends with an optional section on the azimuthal magnetic field in the air gap.
