Suppose that a dc machine is designed such that the voltage applied to the field VF is equal to the voltage VT applied to the armature. In a well-designed machine, which current, IF or IA, is larger under full-load operating conditions? Why? What do you estimate as an acceptable value for the ratio IA/IF under full load?
