DC Generators and Controls  DC generators transform mechanical energy into electrical energy.  As the name implies, DC generators produce direct current and are typically found on light aircraft.  In many cases, DC generators have been replaced with DC alternators.  Both devices produce electrical energy to power the aircraft’s electrical loads and charge the aircraft’s battery.  Even though they share the same purpose, the DC alternator and DC generator are very different. DC Generators and Controls  DC generators require a control circuit in order to ensure the generator maintains the correct voltage and current for the current electrical conditions of the aircraft.  Typically, aircraft generators maintain a nominal output voltage of approximately 14 volts or 28 volts. Generators  These principles show that voltage is induced in the armature of a generator throughout the     entire 360° rotation of the conductor. The armature is the rotating portion of a DC generator. As shown, the voltage being induced is AC. [Airframe Figure 9-40] Since the conductor loop is constantly rotating, some means must be provided to connect this loop of wire to the electrical loads.
