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. Both
cross-sectional and developed views of the distributions are presented.
