Sinusoidal windings: Field space distributions at time t
One phase of a stator 2-pole sinusoidal winding is pictured.The size of the
red circles gives a measure of this spatial distribution. The winding normally
carries a time-varying current usually sinusoidal. At a given time,
the air-gap field B
is also sinusoidally
distributed in space 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 varies sinusoidally with time.
