we have 8,300,000-r- 96,000 = 86.5 square inches as the area of cross-section of a pole-core. Making them circular in cross-section, we have 2 v86.5 -^ n= 10.5 inches, as the diameter of the pole-cores. Fig. 258. Makingthe radial length of the cores three-fourths the diameter, we get | X10.5 = 7|… … Supersedes No. 1580-D Fig. 259. Make-Up of Pole-Shoe of GeneratorWhose Construction is Described in Text know the flux-density and the total flux. The latter is 8,300,000-T- 2 = 4,150,000, page 76; while, if we make the yoke of castiron, the flux-density should be about 41,000, Table IV;…
