Generation Information

Charging System:

The charging system uses generator output to keep electrical loads. the battery charged at a constant level under various
electrical loads.

Operation
Rotation of the excited field coil generates AC voltage in the stator.
This alternating current is then rectified through diodes to procedure DC voltage. Refer to the waveform shown in the illustration at left.
The average output voltage fluctuates slightly with the generator load condition.
When the ignition switch is turned on, current flows in the field coil, causing initial excitation of the field coil.
When the stator coil begins to generate power after the engine is started, the field coil is excited by the output current of the stator coil.
The generator output voltage rises as field current increases and falls as field current decreases. When the battery voltage (generator S terminal voltage) reaches a regulated voltage of Approx. 14.4 V, the field current is cut off. When the battery voltage drops below the regulated voltage, the voltage regulator regulates the output voltage to a constant level by controlling the field current.
In addition, when the field current is constant, the generator output voltage rises as the engine speed increases
