EXAMPLES 7 1. Sketch neat graphs to show the internal or open-circuit characteristics of a separately-excited d.c. generator. Why is a field regulator necessary with such a machine? A four-pole d.c. generator gives 410 V on open circuit when driven at 900 rev/min. Calculate the flux per pole if the wave-connected armature winding has 39 slots with 16 conductors per slot. 10219 w
