Description & Operation: Generator

When the engine is started inside the generator the magnetized rotor turns within the stator windings, generating 3 phase alternating current and a voltage that rises rapidly with rotor speed. The field diode in the rectifier pack converts the alternating current into direct current flowing through the field windings. This causes an increase in the magnetic influence of the rotor, resulting in energy output higher than the battery level. The field current increases with rotor speed and thus increases the generated current and voltage until the generator is producing electrical output at an energy level higher than the battery.
