The old surface-wound altemators had extremely good regulating characteristics due to their low armature self-induction and low armature reac- tion consequent upon tlieir large air-gaps. The writer does not know what value the current rose to, on steady short-circuit, compared with the normal rated current, but it \vas probably four or five.

Wb Flux Linkage, Inductance, and Energy 11 and Bg = = T A~= ~ractice Problem For the magnetic structure of Fig. with the dimensions as given in Example , the air-gap flux density is observed to be Bg = T. Find the air-gap flux ~b and, for a coil of N -- turns, the current required to produce this level of air.
