DC GENERATORS

So that two similar machines will pass approximately equal currents to the load

To reduce the combined effect of armature reaction of both machines

To increase the series flux

To increase the speed and hence generated e.m.f.

To increase the generated e.m.f.

So that the two identical machines will pass approximately equal currents to the load

To reduce the combined effect of armature reaction of both the machines

To increase the series flux
