Terminal A circuit
•
Terminal A circuit is used to detect battery voltage. This voltage is used to determine generator output voltage.
This circuit is used to supply current to the field coil (rotor). The amount of current supplied to the field coil
(rotor) determines the generator output current.
•
The phase difference in the circuit of the two
stator coils causes the electromagnetic pull
between the rotor and the stator to be eliminated
logically. Due to this, electromagnetic vibration
and generator operation noise (electromagnetic
noise) have been reduced.
•
The pulsation occurring through voltage rectifying
is minimized, as a result, stable voltage output is
supplied due to the adoption of two stator coils
with the phase difference.
