ficient ofdispersion not only varies with different typesof machine, but is not generally constant evenin a given machine, since it rises with theexcitation. Moreover, when a large armaturecurrent flows, the demagnetizing action of thelatter directly aids dispersion, as it usuallyproduces an m. m.… … Fig. 96.
