DC Generators The armature winding of a dc machine is place on the rotor to ______ Save iron Facilitate commutation Reduce losses Reduce armature reaction Save iron Facilitate commutation Reduce losses Reduce armature reaction ANSWER DOWNLOAD EXAMIANS APP
DC Generators When two D.C. series generators are running in parallel, an equalizer bar is used To increase the speed and hence generated e.m.f. To increase the series flux 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 speed and hence generated e.m.f. To increase the series flux So that two similar machines will pass approximately equal currents to the load To reduce the combined effect of armature reaction of both machines ANSWER DOWNLOAD EXAMIANS APP
