SINUSOIDALLY DISTRIBUTED
SINGLE-PHASE WINDING
A sinusoidally distributed winding is excited with a
sinusoidal current. The resulting pulsating radial flux density distribution is
shown plotted along a circular path in the air gap (which is greatly enlarged
for visual purposes). A 2-pole and 4-pole configurations are illustrated. In
the 2-pole view, the spatial sinusoidal field distribution can be represented
by a 2D space vector located along the (horizontal) axis of the winding; the
vector points to where the field is maximum positive and has a length
proportional to the maximum field strength at that instant.
