One phase of a stator 2-pole sinusoidal winding is pictured. For simplicity, the winding is shown as
concentrated. It carries a sinusoidal time-varying current. The air-gap field B is sinusoidally
distributed in space with amplitude varying with time as
seen in this animation. This sinusoidal distribution may be represented by a
space vector oriented along the horizontal axis.

distributions when the current excitation is constant.
