Opening Source Excerpt
Section titled “Opening Source Excerpt”V. Effect of Saturation on Magnetic Distribution 46. The preceding discussion of Figs. 92 to 95 omits the effect of saturation. That is, the assumption is made that the mag- netic materials near the air gap, as pole face and armature teeth, are so far below saturation that at the demagnetized pole corner the magnetic density decreases, at the strengthened pole corner increases, proportionally to the m.m.f. The distribution of m.m.f. obviously is not affected by satu- ration, but the distribution of magnetic flux is greatly changed thereby. To investigate the effect of saturation, in Figs. 96 to 99 the assumption has been made that the air gap is reduced to one-half its previous value, la = 0.5, thus consuming only one- half as many ampere-turns, and the other half of the ampere- turns areSource-Located Theme Snippets
